It carries a 2 m cable with an angled M12 socket, rated for the AS-i operating voltage range of 26.5 to 31.6 V, with a continuous rated current of 3 A and a maximum contact load of 4 A. ## Washdown-ready build The IP67/68/69K rating means the connector body and cable entry survive high-pressure hot-water washdown cycles — common in food, beverage, and pharmaceutical lines where the M12 socket sits on the machine frame, not inside a cabinet. Mounting is by screw fixing; the cable end uses an insulation-piercing method that taps directly into the AS-i flat cable without stripping or cutting the feeder. ## Pinout and environment Socket assignment: pin 1 = ASI+, pin 2 = AUX−, pin 3 = ASI−, pin 4 = AUX+. The manufacturer note states the cable must not end in the feeder — meaning the branch cable is a tap, not a termination point for the AS-i trunk.","metaTitle":"Siemens 3RK1901-2NR22 AS-i M12 Branch Cable, 4A, IP67/68/69K","metaDescription":"Siemens 3RK1901-2NR22 AS-Interface M12 branch cable assembly. 2m cable, angled M12 socket.
