The fastest cable quotation is not the shortest email. A complete request lets engineering check compatibility, price the correct materials and prepare a drawing without repeated clarification.
Best starting package: mating-part details, end-to-end pin map, cable construction, length definition, environment, quantity, schedule and required tests.
The 12 details to include
- Connector A manufacturer, series, part number or interface drawing.
- Connector B or all branch-end interfaces.
- Contact-face orientation and gender for every end.
- Complete pin-to-pin map, including shields and unused conductors.
- Signal, protocol, voltage and current for each circuit group.
- Cable type, conductor size, pair construction and shielding.
- Length and the exact datums used to measure it.
- Straight or right-angle exit and right-angle clocking.
- Static, drag-chain or torsional motion requirements.
- Temperature, water, dust, chemicals and UV exposure.
- Labels, colors, overmold, braid, conduit and packaging.
- Prototype quantity, annual volume, delivery target and acceptance tests.
Define length so production can measure it
“Two metres” can mean cable cut length, connector tip-to-tip length or distance between defined connector datums. Right-angle bodies and branches make the difference significant. Put the nominal dimension, tolerance and measurement points on the drawing.
Separate electrical test from application validation
| Continuity / shorts | Checks the intended pin mapping and unintended connections. |
|---|---|
| Insulation resistance / high potential | Checks defined isolation characteristics under an agreed method. |
| Shield continuity | Checks the specified screen path; it does not alone prove network performance. |
| Functional test | Confirms protocol, image transfer, trigger timing or powered operation in a representative system. |
| Motion / environment | Validates the assembly under agreed bending, torsion, temperature or ingress conditions. |
Approve one controlled definition
LMConn cable documentation covers industrial Ethernet, machine-vision I/O, USB 3.0 Micro-B and mixed industrial interfaces. Whether the assembly is standard or customized, approval should end with one revision-controlled drawing that purchasing, production and inspection can all use.
