The TE Connectivity 1546350-2 is a size 23 backshell with integrated cable clamp for the CPC (Circular Plastic Connector) series. The kit includes the clamp halves, a flat ring, and the mounting screws, so no separate hardware sourcing is needed. The 1 3/8-18 UNEF thread mates directly with the shell of a size 23 CPC connector. The 0.703" (17.86 mm) cable opening accepts a cable bundle up to that diameter — measure your cable OD before ordering to confirm the clamp closes fully around the jacket.
Thread Fit and Cable Range
The thread is 1 3/8-18 UNEF, a standard size for CPC size 23 shells. This is not a metric thread — it is a UNEF (Unified Extra Fine) series, so confirm your mating shell uses the same thread form. The cable opening is 0.703" (17.86 mm), which is the maximum bundle diameter the clamp can grip. If your cable is smaller, the clamp still tightens down; if it is larger, you need a different backshell size or a straight-exit version with a larger bore.
