The Siemens 3RK1902-4HB15-5AA0 is a pre-assembled M12 control cable, angled at one end and open on the other, intended for field-wiring connections to SIRIUS sensors, actuators, or distributed I/O blocks in industrial automation panels. Rated IP67, the connector body and cable entry withstand washdown and wet-area exposure — suitable for food-and-bev lines, washdown zones, or outdoor cabinet interfaces where moisture ingress is a concern. The 5-pole M12 connector uses A-coding per the standard, with a threaded M12 x 1 interlock. Each pin carries up to 4 A at a maximum DC operating voltage of 125 V, which covers the signal and low-power supply needs of most 24 VDC sensor/actuator circuits in a control cabinet.
Cable construction and environmental limits
The cable is 1.5 m long, 5 mm outer diameter, with a black PUR-OB sheath that resists mineral oils, greases, and ASTM oil 2 — though the resistance is conditional and must be verified against the specific fluid and temperature in the application. The inner conductors are 0.34 mm² stranded, insulated with polypropylene. The cable is unshielded and the strain relief is cast into the connector body. The angled outlet helps route the cable tight to the panel wall or along a cable tray, saving bend radius compared to a straight connector.
Approvals include UL, CSA, and IEC — covering North American and international installation standards.
