Cable Assemblies for Test & Measurement
A measurement lead is part of the instrument. If it adds noise, leaks current or changes between builds, the measurement is wrong — and the instrument will get blamed for it.
What this application demands
These are the constraints that change the design. Everything else is a normal cable.
- Signal integrity
- Capacitance, leakage and shielding determine whether a low-level measurement survives the cable. Insulation resistance of 100 MΩ at 500 VDC and, where needed, above 1 GΩ.
- Shielding integrity
- Coverage, drain termination and connector bonding, verified end to end — not assumed from the cable construction.
- Precise pinout
- Pinout is verified 100% against your wiring schedule. On high-pin-count and multi-channel builds this is the defect that actually occurs.
- Small batch, high mix
- Ten variants of fifty pieces is a different production problem from five thousand of one part. We run both.
- Repeatability between builds
- Specifications and tooling retained under your part reference, so a reorder two years later matches the original.
Typical builds
- Precision measurement lead sets
- Shielded multi-channel harnesses
- Breakout boxes and adapter assemblies
- Fixture and probe cabling for production test
- Low-level signal and high-impedance connections
Electrical limits we report
| Test | What it catches | Typical limit |
|---|---|---|
| Continuity and pinout | Miswiring, open and crossed circuits | 100% of units, <1–5 Ω |
| Insulation resistance | Leakage paths, contamination, damaged insulation | ≥100 MΩ at 500 VDC, up to ≥1 GΩ |
| Dielectric withstand (hipot) | Clearance and insulation defects | 1000–1500 VAC for 1 s, cut-off <1–5 mA |
| Contact resistance | Poor crimps and degraded contacts | ≤10–20 mΩ |
Tell us the measurement, not just the connector. Signal type, expected magnitude and the bandwidth that matters are what decide the cable construction.
What we ask before quoting
Answer these with the drawing and the quotation will be meaningful on the first pass.
- Signal type, magnitude and bandwidth
- Shielding and grounding scheme
- Pinout convention and labelling requirements
- Quantity per build and expected reorder pattern
- Any calibration or documentation requirement
Send the specification and the mating connectors
We will confirm what the cable has to survive, flag anything that will cost you money without adding function, and quote against your drawing.
