No terminating resistor is integrated, so you add one at the bus end if needed. The IP67 rating means the connector body and the mated interface withstand washdown — suitable for food-and-bev lines, packaging cells, or any zone where hoses are used. The housing is zinc diecast, nickel-plated; the contact is brass with gold plating. Cable entry accepts 6–8 mm diameter cable, secured by a pressure screw and pinch ring. The M12 x 1 thread with B-coding mates directly to standard PROFIBUS device ports and junction boxes. The angled outlet keeps the cable profile low against the panel or machine frame — useful in tight enclosures or along cable trays where a straight plug would snag. Screw terminals accept flexible conductors up to 0.75 mm². The 100 mating-cycle mechanical life is typical for field-attachable M12s; plan for occasional replacement if the connector is frequently disconnected during line changeovers.","metaTitle":"Siemens 3RK1902-1BA00 M12 PROFIBUS Connector, 5-pole B-coded","metaDescription":"Siemens 3RK1902-1BA00 M12 angled PROFIBUS connector, 5-pole B-coded, screw terminals, IP67, 4 A, 125 V.
