The Siemens 3RK1902-3DA00 is a 24 V socket with a 7/8" angled plug interface, 5 poles, and screw terminals rated for a maximum conductor cross-section of 1.5 mm² and a cable diameter of 6 to 8.7 mm. It carries up to 9 A per pin at a maximum operating voltage of 250 V. The IP67 rating means the socket and its mated connector are protected against dust ingress and temporary immersion in water — suitable for washdown zones, outdoor enclosures, or food-and-beverage lines where hose-down cleaning is routine.
RoHS conformity is confirmed, so it meets the EU directive on restricted hazardous substances for new equipment.
Construction and integration
The housing uses zinc diecast, nickel-plated, and polybutylene terephthalate materials; the fixed connector part is polyamide and polyurethane. Contacts are brass with gold plating, and the strain relief uses a pressure screw and pinch ring. The angled cable outlet helps route cables close to the panel wall or enclosure lid.
