The Siemens 3RK1902-3NC10 is a 7/8" connector assembly — socket angled on one end, plug angled on the other — with a 10-meter unshielded polyurethane cable, populated on both sides. It carries 5 poles rated at 8 A per pin, with a 3 kV surge voltage resistance, and is protected to IP67. The 7/8" thread interlock is standard for North American-style quick-connect power and signal cabling in industrial automation, commonly used on distributed I/O blocks, motor starters, and sensor/actuator junction boxes where a sealed, field-attachable connection is needed without hardwiring.
IP67 means the connector is dust-tight and protected against temporary immersion in water — suitable for washdown zones, outdoor cabinets, and wet-floor areas in food-and-bev or automotive lines. The 8 A per pin ampacity covers most sensor and actuator loads; for higher-current devices like small motors or valves, verify the total draw per pin stays under that limit. The 5-pole configuration (5 electrical cores, 5 x 1.5 mm² stranded) matches standard 5-wire sensor/actuator cables (e.g., 24 VDC, 0 V, plus three signal or two signal + PE). The angled outlet on both ends reduces cable strain in tight panels or cable trays — the minimum single-bend radius is 65.25 mm, multiple-bend radius 87 mm, so plan routing accordingly. The molded strain relief and polyurethane sheath (8.7 mm outer diameter, 0.2 mm tolerance) resist oil, grease, and mineral oil conditionally — check the specific fluid and temperature in your application.
