The Siemens 3RK1902-4HB50-5AA0 is a pre-assembled M12 control cable with an angled connector on one end and flying leads on the other. It carries five poles in an A-coded keyway, a 5-meter PUR-jacketed cable with 5 x 0.34 mm² conductors, and is rated for 4 A per pin at up to 125 VDC. The IP67 rating means the connector end withstands washdown and wet environments — suitable for sensor/actuator drops on food, beverage, or outdoor conveyor lines where moisture is routine.
The M12 x 1 threaded coupling locks securely against vibration, and the angled cable outlet keeps the bend radius tight against the panel or junction box — useful when the connector sits in a cramped gland plate or behind a DIN-rail terminal block. The PUR outer jacket (PUR-OB) resists mineral oil, grease, and ASTM oil 2, though compatibility should be verified per the application.
