Turck RSFRKF40/22 Panel Feed-Through Receptacle Connector

Turck RSF RKF 40/22 panel feed-through receptacle is a double-ended Mini Fast connector that enables power and signal pass-through through a panel, featuring a 7/8"-16 UN 4-pin male receptacle on the front and a 7/8"-16 UN 4-pin female receptacle on the rear. The unit uses front-mount male and rear-mount female orientations with a 7/8"-16 UN mounting thread, and combines brass (CuZn) gold-plated contacts in a black TPU contact carrier inside a nickel-plated brass housing for rugged industrial use. It is rated for 600 VAC and 9 A, supports a tightening torque of 0.8–2.0 Nm, provides IP67 protection when mated (NEMA 1, 3, 4), and operates from -40 °C to +105 °C, with an NBR gasket forming the panel seal. UL 2238, CSA C22.2 No. 182.3, CE, UKCA, and RoHS approvals apply, and common applications include PLC control panels, machine enclosures, industrial control cabinets, and factory automation equipment, as well as conveyors, packaging machinery, material handling, machine tools, process automation, distributed I/O, and sensor/actuator interfaces.
