It's the part you reach for when you need a clean, sealed drop point on an AS-i line — one M12 connection, no extra 24V pair to run. Rated IP67/68/69K, so it handles washdown environments — food processing, car wash tunnels, or anywhere a hose is the cleaning tool. The insulation piercing method for the flat cable means you don't strip or splice; the connector bites through the jacket. Contact load rating max 4 A, operating voltage per AS-Interface spec 26.5 to 31.6 V. The socket assignment is pinned: pin 1 = AS-i '+', pin 3 = AS-i '-'. Ambient range -25 to +75 °C operating, -25 to +85 °C storage. ## Installation Note One spec note worth flagging: the cable must not end in the feeder. That means the flat cable should run through or past this branch, not terminate at it. Plan your AS-i trunk routing accordingly — this is a tap, not a dead-end cap.","metaTitle":"Siemens 3RK1901-1NR10 AS-i M12 Branch, IP67/68/69K, 4A","metaDescription":"Siemens 3RK1901-1NR10 AS-Interface M12 branch U_ASI without Uaux.
