Turck U2281-3 Actuator And Sensor Extension Cordset

The Turck U2281-3 RSM RKM 46-3M Actuator and Sensor Extension Cordset is a double-ended extension cable with straight 7/8"-16 UN 4-pin Mini Fast male on one end and straight 7/8"-16 UN 4-pin Mini Fast female on the other, built on a 3 m yellow flexible PVC service cable for reliable power and signal transmission in industrial automation systems. It uses 4 × 16 AWG (1.5 mm²) conductors with bare copper, rated for 600 V and 10 A, and a overall cable diameter of 10.01 mm; the contact system features brass (CuZn) with gold-plated contacts, while the carrier and connector bodies are TPU yellow and the coupling nuts brass (CuZn) nickel-plated, with a tightening torque of 2 Nm and a mechanical life exceeding 100 mating cycles. The assembly is designed for rugged environments with IP67, IP68, IP69, and IP69K protection (when mated) and is compatible with NEMA 1, 3, 4, 6P, and 12 enclosures; operating temperature ranges are -40 °C to +105 °C static, +5 °C to +105 °C flexible, and -10 °C to +105 °C during installation, with minimum bending radii of ≥5× cable diameter static and ≥10× dynamic. Special features include a flexible service cable, sunlight and oil resistance, -40 °C cold bend rating, UL 1100 and CSA FT2 flame ratings, and approvals from UL 2238, CSA C22.2 No. 182.3, CE, UKCA, and RoHS. It is commonly used in PLC control panels, conveyor systems, machine tools, distributed I/O stations, motor controls, sensors, actuators, and broader factory automation equipment where a 4-pin Mini Fast extension connects sensors, actuators, valve manifolds, and field devices; system integrators frequently rely on it for equipment replacement, retrofits, new installations, and control-system expansion.
