It's a 5-pole connector rated IP67, meaning the mated connection holds up against washdown and dust ingress in industrial environments. The molded strain relief and angled cable outlet keep the cable routed tight against the panel or junction box, which matters when you're trying to avoid snag points on a moving machine. That puts it in the range for powering sensors, actuators, or small valves—think 24 VDC solenoid banks or 120 VAC prox arrays—where you need a rugged, field-attachable or pre-molded connection that won't let moisture into the pin cavity. ## Signal integrity and mechanical life The cable is unshielded, so if you're running this next to a VFD output or a welding line, expect to pick up coupled noise. For clean signal paths, keep the cable separated from high-energy power runs or plan on an external ferrite. The 5-million-cycle flex life on the cable is solid for continuous-flex applications like cable tracks, but the mating cycles are only rated for 100—this is a connect-and-forget connector, not a daily disconnect point. The 5 x 1.5 mm² stranded conductors handle the 8 A per pin comfortably, and the 3 kV surge rating gives you headroom for transient spikes common on 400 VAC lines. The insulation colors are standard: black, blue, green-yellow, brown, white—no surprises when you're terminating into a terminal block or I/O card. ## Approvals and lifecycle This part carries CSA approval but not UL, cUL, CCC, or C-Tick. That means it's accepted in Canadian industrial installations, but for a UL 508A panel destined for the US market, you'll need to verify the system-level listing with your panel builder. It is RoHS compliant, so no material restriction issues for EU-bound machinery.","metaTitle":"Siemens 3RK1902-3GB30 7/8\" Angled Socket, IP67, 5-Pole, 3m C","metaDescription":"Siemens 3RK1902-3GB30 7/8\" angled socket, 5-pole, 3m PUR cable, IP67, 8A per pin, 3kV surge, CSA approved, RoHS.
