Standard twisted and shielded instrument cable

Asked by Ameya_Jos 1 year, 8 months ago | 1 Answers

Does anyone have experience pulling standard twisted, shielded instrument cable and having construction perform field connections to Turck type connectors? 

Buying standard cable vs. pre-fab cable from Turck is lower cost, but there is concern about a few things, one of which is the likely quality of the connection made in the field. 

Thanks.

We did that at Fayetteville many years ago. In particular, it was on block valve limit switches. I think we used keyed 120VAC plug connectors for the solenoid and Turck (actually T&B back then) on limit switches. Intent was to permit an operator to pull a valve and not require electrician.

No problem from what I recall. One side of Turck installed in shop on limit switches. Mating side installed in condulette in field. Helps to provide construction a special wiring schematic with required details [color coding] for field wiring. For installation, need to confirm location of condulettes and length of Turck cables and appropriate labeling to prevent mixups.
