Rated IP67, it handles washdown environments on the line — the housing is zinc diecast nickel-plated, the contact is brass/bronze with gold plating, and the cable outlet is angled with a pressure-screw strain relief. The M12 x 1 thread plug interlock keeps the connection secure under vibration. Rated 4 A per pin maximum ampacity at 125 V, with a surge voltage resistance of 0.8 kV and pollution degree 3. The 100 mating cycles mechanical service life is typical for a field-attachable M12 connector — this is not a high-cycle panel-side umbilical, it is a device-end drop meant to be plugged in and left. The B-coding is specific to PROFIBUS; a standard A-coded M12 will not key in. Accepts flexible conductors up to 0.75 mm² via the screw terminals. Cable inlet diameter 6 to 8 mm. Dimensions: 54 mm height, 43 mm width, 20 mm depth — compact enough for a crowded junction box near a sensor or actuator. Operating and storage temperature range -25 to +85 °C.","metaTitle":"Siemens 3RK1902-1DA00 M12 PROFIBUS Socket, IP67, B-Coded, 5-","metaDescription":"Siemens 3RK1902-1DA00 M12 socket for PROFIBUS, angled, 5-pole, B-coded, screw terminals, IP67, 4A per pin, 125V, RoHS.
