Encoder Cable with Individually Screened Pairs

Protecting a millivolt signal

An encoder output is a small, fast signal travelling through an environment full of switching noise. It survives on screen topology and capacitance, not on conductor size. Each pair is twisted to cancel magnetic pickup, individually screened against capacitive coupling from its neighbours, and the assembly is finished with an overall braid at 85 % coverage or better, brought out to a drain that terminates at both ends.

Matched to the run length

Cable capacitance and conductor resistance together decide how far a given pulse train can travel before it is unrecognisable, so the cross-section and the dielectric are chosen for the actual installed length rather than the shortest available. Tell us the drive, the encoder type, the pulse frequency and the run length and we will specify a cable that still works with margin at the far end.

Applications

This construction is supplied into the following installations. Tell us which one applies and we will confirm the governing requirement.

Customisation

Core count and cross-section, screen arrangement, sheath compound and colour, print legend, length and termination are all built to order. Send the requirement — including the failed OEM part if this is a replacement — and we will propose the construction and confirm the lead time.
