What the IP67 rating buys you on this M8 receptacle
The TE Connectivity T4033014041-000 is an M8 A-coded receptacle — 4 female sockets in a metal shell, terminated by solder cup, meant to be panel-mounted with the rear side nut. The 3 A per-contact rating at 30 V is standard for signal-level M8 interconnects in automation control and industrial telecom gear — enough for 24 V sensor loops and low-power actuators, not a power bus.
Termination choice: solder cup vs crimp
This receptacle terminates by solder cup — you tin the wire, insert it into the cup, and flow solder. It's a field-service-friendly method if you have an iron and heat-shrink, but it's slower than crimp on a harness line. The trade-off: no crimp tooling investment, and the joint is inspectable. The gold-over-nickel mating finish (3.00µin) handles the corrosion side of the IP67 seal; the nickel-plated copper alloy shell gives the threaded fastening a consistent mating surface cycle after cycle.
