1. Four decisions before commissioning
Keep DC resistance and pair integrity separate
For CAN, about 60 Ω can reflect two 120 Ω terminators. It does not prove that H/L share a twisted pair or that the mapping is correct.
Evidence and limits ↓Distinguish shared-power interfaces
EtherCAT P carries power and communication together. A generic power-to-data isolation rule is unsuitable for that assembly.
Evidence and limits ↓Evaluate lead loss against the measurement budget
Remote sensing can compensate excitation lead losses when supported. Cable length alone does not establish the required wiring or residual accuracy.
Evidence and limits ↓The worksheet is an editorial review method. It compares selected entries with your drawing limits and records unresolved items; it does not inspect hardware or certify an assembly.
2. Front and rear views: preserve the contact identity
For the same insert held with a common key reference at the top, changing from the mating face to the termination side reflects left and right. The contact identifier stays attached to the same physical contact. A different mating part must be checked against its own drawing; do not mirror one part and assume the partner matches.
No clockwise numbering convention is assumed. Real inserts can use rings, rows, center contacts or mixed layouts. The sketch teaches perspective only.
Source and scope: LEMO B series. Multiple insert configurations and termination options; shell family alone does not identify the insert.
3. Identify the mechanical and electrical interfaces separately
| Check | Evidence to capture | If unknown |
|---|---|---|
| Connector identity | Manufacturer, complete part number, insert and mating part | Request both part drawings; do not order by shell name alone |
| Role and contact gender | Cable plug / receptacle / breakout, plus pins / sockets / mixed | Photograph each face and mark which drawing describes it |
| View and key reference | Mating or termination view; orientation of the reference feature | Stop translation until the drawing view is identified |
| Electrical allocation | Power, return, data, sense, shield and NC by contact | Keep unknowns unassigned; avoid wire-color inference |
| Ratings and environment | Supply limits, current, seal, torque and cable motion ratings | Obtain exact component specifications |
Source and scope: LEMO B series. Multiple insert configurations and termination options; shell family alone does not identify the insert.
4. Pair continuity is only one part of signal integrity
Record each physical twisted-pair identifier alongside both signal contacts. End-to-end continuity can succeed even when differential signals use separate twists. Inspect the cable construction or use a suitable cable tester in addition to checking the contact map.
| Assembly | Useful observation | Cannot establish by DC reading |
|---|---|---|
| Detached passive cable | Conductor paths and unintended connections at an approved test voltage | Operating link quality, loaded voltage or EMC immunity |
| Unpowered high-speed CAN bus | Combined termination resistance and gross connection issues | Correct pair twisting, waveform margin or baud-rate support |
| Ethernet / EtherCAT | Documented wiremap and link diagnostics | Transmission-line impedance from a multimeter reading |
| Shared power/data | Equipment-specific supply and communication procedure | Isolation between functions deliberately sharing conductors |
Source and scope: Kvaser: test CAN termination. Nominal two-end CAN termination and resistance check; not Ethernet or a power safety test.
Source and scope: Beckhoff: EtherCAT P. Shared communication/power architecture and dedicated connectors; not an HXF support claim.
5. Use a repeatable test record
- Record cable identity, both connector part numbers, drawing revisions and the responsible reviewer.
- Establish the test assembly and de-energize it under the approved procedure. For passive-cable comparisons, disconnect both ends from electronics.
- List every intended path and every unintended-path check, including NC contacts and shield. Record instrument, range, lead compensation and permitted test voltage.
- Measure each path and retain the full list. Enter the lowest unintended-path resistance and highest conductor resistance in the summary; use limits from the same test procedure.
- Review mapping, keying, pair membership, shield topology and supply requirements. Export unresolved items for engineering disposition.
Do not apply a megohmmeter voltage to connected sensor electronics unless the manufacturer explicitly approves that test. An OL reading is not a measured infinity: record the instrument range and follow the procedure for a lower-bound observation. Numeric summary fields stay blank until a supported value is available.
6. How the worksheet reaches its result
| State | Meaning | Next step |
|---|---|---|
| HOLD | Required identification, readings or confirmations are missing; or the assembly needs specialist interpretation | Resolve listed open items and attach the test procedure |
| INPUT_ERROR | Invalid numeric entry, duplicate source contact or a reading outside an entered drawing limit | Correct the record or investigate the cable; do not hide a failed reading |
| RECORDED | Detached-cable summary is complete and within user-entered inclusive limits | Obtain engineer sign-off using the full per-path record |
| DEMO | Fictional example; always marked as illustrative, even after edits | Reset to begin a real review |
Blank fields are unknown, not zero. Negative, nonfinite, malformed and over-range values are rejected. Zero is a valid observation, while acceptance limits must be positive. At a limit, uncertainty and guard bands still belong to the approved procedure. The tool cannot verify a typed limit or a user-confirmed checkbox.
7. Supply, shielding and protective earth
| Item | Record | Avoid |
|---|---|---|
| Supply | Polarity, contact allocation, allowable range, current limit and loaded drop | Assuming all sensors use 24 V or a universal ±10% window |
| Shield | Specified termination and continuity through connectors | Treating a shield as a universal power-return conductor |
| Signal return and PE | Intentional bonds, isolation and protective-earth requirements | Removing PE or changing a bond solely to raise resistance |
| Shared power/data | Exact interface, compatible equipment and approved test setup | Applying isolated power/data rules to a shared conductor |
Record any host voltage check separately under the equipment procedure, with the sensor disconnected as required. A no-load reading alone cannot establish the voltage at the sensor under operating current.
Source and scope: Beckhoff: EtherCAT P. Shared communication/power architecture and dedicated connectors; not an HXF support claim.
8. Analog excitation: assess loss against the budget
For a simple full bridge with two equal excitation leads, a series-divider model gives Vbridge / Vsource = Rbridge / (Rbridge + 2Rlead). This is a simplified circuit model, not a six-axis calibration model. Amplified or digital sensors can use different internal architectures.
Remote sensing must be supported by the sensor and acquisition hardware. Its suitability depends on lead loss, supply compliance, stability and the measurement budget. Residual error remains configuration-dependent. No fixed accuracy or cable-length cutoff is established on this page.
Source and scope: NI-9237 getting started. Bridge lead resistance and remote sensing for that acquisition system; not a universal accuracy specification.
9. Three worked review examples
All cases below are hypothetical teaching examples, not customer tests or product performance results.
Detached cable with an incomplete map
Assume a fictional procedure specifies minimum isolation 10 MΩ and maximum conductor resistance 0.5 Ω. Enter 50 MΩ and 0.35 Ω. These readings meet the entered limits, but missing contact mapping keeps the record on HOLD. Load the example above to see the open items.
CAN bus reads 120 Ω
Assume the planned bus has two nominal 120 Ω end terminators. Their parallel equivalent is 60 Ω. A 120 Ω reading warrants checking whether one terminator is missing or disconnected. The worksheet records the value and keeps engineering interpretation open.
Shared-power interface is misclassified
An engineer initially selects detached cable for a connection carrying shared power and data. Change the assembly to shared power/data: previous readings and confirmations clear. The worksheet requests the equipment procedure instead of applying passive-cable isolation limits.
Source and scope: Kvaser: test CAN termination. Nominal two-end CAN termination and resistance check; not Ethernet or a power safety test.
10. Risks, costs and practical alternatives
| Risk | Decision cost | Minimum mitigation / alternative |
|---|---|---|
| Misread drawing view or supply allocation | Cable rework and possible hardware damage | Hold connection; get the exact drawing and trace contacts |
| DC checks miss pair or link faults | Repeated commissioning downtime | Add physical pair verification and equipment-specific link tests |
| Cable route does not match motion or sealing needs | Replacement harness, qualification time and spares | Request motion, bend, seal and assembly ratings for that cable; validate the route |
| Unapproved measurement method | Invalid readings or electronics damage | Use a detached passive cable where applicable; otherwise obtain the approved equipment test |
| Incomplete evidence at handover | Repeat inspection and delayed commissioning | Attach per-path readings, drawing revision, instrument and reviewer disposition |
No price, endurance, compatibility or delivery promise is implied. If drawings are unavailable, the executable next step is a drawing request with connector photographs and complete part numbers.
11. Questions from mapping to handover
Can I wire an HXF sensor using this page?
Obtain the approved configuration drawing first. This page provides a review workflow and a user-entered worksheet, with no HXF contact allocation.
Does the circular sketch show an M12 pinout?
No. Letters A–D demonstrate reflection of the same insert. They are not contact numbers, a standard layout or a mating connector map.
Does a rear view change the contact identity?
No. A contact keeps its identifier. Only its apparent position changes; locate the reference key in both views.
Is a female contact always a cable plug?
Identify body role and contact gender separately from each part drawing. Do not infer one from the other.
Does matching the key guarantee electrical compatibility?
No. Keying and insert fit are mechanical checks. Confirm the signal assignments, supply, ratings and mating part numbers separately.
Can I infer a signal from its wire color?
Use the cable drawing and continuity tracing. A color is an identifier in a specific assembly, not an electrical function guarantee.
What does an open or OL meter display mean here?
It indicates an instrument-range or open-circuit observation. Leave the numeric reading blank and attach the actual range and observation. Do not enter infinity or an invented resistance.
Can I use an insulation tester on an attached sensor?
Use only the equipment-approved method and test voltage. The passive-cable comparison requires the cable to be disconnected from electronics; do not apply an insulation tester to attached electronics by inference from this worksheet.
Does 120 Ω pass a complete CAN bus?
Two nominal 120 Ω end resistors give about 60 Ω in parallel. A reading near 120 Ω can indicate one terminator. Check the intended topology; the tool records it without a universal pass window.
Does an Ethernet pair measure 100 Ω on a multimeter?
The transmission-line impedance and a DC resistance measurement are different quantities. Use the equipment cable and link test procedure.
Should signal ground be isolated from protective earth?
Follow the equipment grounding design. Intentional bonds, isolation and capacitive connections vary. Never remove protective earth to change a worksheet reading.
Why is there no ready-for-power result?
A worksheet records selected observations. It cannot verify the physical wiring, supply behavior, equipment approval or every failure mode. A responsible engineer must authorize the commissioning procedure.
When should I choose six-wire remote sensing?
Check acquisition support, allowable lead loss, excitation compliance and uncertainty budget. No universal three-meter rule or fixed residual accuracy is established here.
What should I send for a drawing review?
Send both part numbers, drawing revisions, cable identifier, mapping, pair identities, supply specification, measurement setup and per-path results. Include unresolved items rather than marking them passed.
