It carries the AS-i signal and power (26.5–31.6 V per the AS-Interface specification) but no auxiliary Uaux supply. Rated for 4 A continuous, it feeds a single actuator or sensor node on the bus. ## Washdown-ready deployment IP67/68/69K means the connector body and cable entry survive high-pressure hot-water washdown — food-and-bev or chemical processing lines where standard IP67 connectors fail. Screw fixing secures the branch point to a bracket or panel; the insulation-piercing method taps the flat cable without stripping it. ## Cable routing constraint The manufacturer note states the cable must not end in the feeder — meaning the free end of this 1 m pigtail cannot terminate inside the AS-i power supply or gateway housing. It must connect to a device or a termination cap. Plan the drop length accordingly. Listed as current production.","metaTitle":"Siemens 3RK1901-1NR11 AS-i M12 Branch, 4A, IP67/68/69K","metaDescription":"Siemens 3RK1901-1NR11 AS-Interface M12 branch cable, 1 m, 4 A, IP67/68/69K.
