It's a field-wireable connector for 7/8\"-threaded industrial interconnects — think power and signal distribution to sensors, actuators, or I/O blocks in wet or washdown zones. IP67 means the mated connector survives temporary submersion and hose-down — it's at home on food-grade conveyors, packaging lines, or outdoor conveyor sections where water ingress is a daily risk. Rated 8 A per pin with 5 conductors (5 poles, 5 x 1.5 mm² stranded), so it handles moderate sensor clusters or a small valve manifold on one drop. The 3 kV surge voltage resistance gives it headroom for industrial environments with switching transients. The unshielded cable (no shield) means it's for power or non-critical signal runs. If you're carrying analog or fieldbus signals near VFDs, you'll want a shielded variant — this one will pick up noise. ## Mechanical durability Rated for 100 mating cycles and 5 million bending cycles — the molded strain relief and polyurethane jacket handle continuous flex in cable-track or robot-dress applications. Minimum bend radius with single bend is 65.25 mm; multiple bends need 87 mm.","metaTitle":"Siemens 3RK1902-3GB50 7/8\" Angled Socket, IP67, 5m Cable, 8A","metaDescription":"Siemens 3RK1902-3GB50 7/8\" angled socket with 5m PUR cable, IP67, 5-pole, 8A per pin, 3kV surge.
