The 112491-10: It ships as a complete crimp kit: one connector body, one centre contact, one ferrule, and one sleeve — everything needed to terminate a cable in one package. The voltage rating of 500 V is generous for a signal connector — the limiting factor in practice will be the cable's own rating.
Termination and Mating — Crimp and Bayonet Lock
The kit includes the correct ferrule for the shield braid and a sleeve for cable strain relief. The bayonet lock provides a quick, positive mate with a quarter-turn; the locking pins resist vibration-induced disconnect better than a friction-only interface.
