The connection method uses an insulation-piercing technique for the AS-Interface flat cable, so the cable must not end in the feeder — the piercing contacts need the cable to run through the device. ## Environmental and electrical ratings Rated IP67/68/69K, meaning the assembly withstands immersion (1 m depth, continuous) and high-pressure, high-temperature washdown — suitable for food, beverage, and heavy washdown zones on the line. Contact load rating is 4 A max, with an operational current rating of 3 A. The operating voltage follows the AS-Interface specification at 26.5 to 31.6 V. Ambient temperature range is -25 to +75 °C for operation, -25 to +85 °C for storage — the full industrial envelope for unheated plant floors or outdoor cabinets. ## Mounting and wiring Mounts via screw fixing with a tightening torque of 1.65 N·m — the specified torque is tight enough to hold under vibration but below the plastic creep limit of the housing. Socket pin assignment: pin 1 = ASI+, pin 3 = ASI- — the standard AS-i pinout for M12, so it mates directly with any AS-i M12 device or cordset wired to the same scheme.","metaTitle":"Siemens 3RK1901-2NR11 AS-i M12 Branch, IP67/68/69K, 4 A","metaDescription":"Siemens 3RK1901-2NR11 AS-Interface M12 branch cable, 1 m, IP67/68/69K, rated 4 A.
