Practical guidance for specifying custom cables.
Short technical articles for procurement and engineering teams preparing an RFQ.
For engineers specifying cable
Each guide covers one cable decision.
Every article takes on a single choice you hit when a drawing reaches the cable section — bend radius, M12 coding, overmolding, IP rating, derating. The figures are what we build and test to, so you can check them against your own spec.
Lock these five first
Series, pins, length, current, environment. Get one wrong and the quote restarts.
Values, not claims
Bend radius, shielding, derating, IP — every rating is a measured figure you can verify.
From our build floor
Examples are cables we make and test, so the tolerances are what we hold in production.
