Turck U-51645 Industrial Powerfast Extension Cordset

The Turck U-51645 Powerfast Extension Cordset (RSM RKM 34-5M) is a double-ended, 5-meter industrial power cable with straight 7/8"-16 UN 3-pin male and female connectors, designed for high-current power distribution in demanding automation environments. It uses a black TC-ER jacket and Power Tray/Exposed Run/Direct Burial rated construction, and carries 3 × 14 AWG (2.5 mm²) bare copper conductors with PVC/Nylon insulation in green/yellow, black, and white. The assembly is rated for 600 V and 21 A, with a 14.22 mm cable diameter and a minimum static bend radius of ≥5× diameter (dynamic ≥10×). Terminations feature brass (CuZn) contacts with gold plating; connectors have TPU (male) and PVC (female) bodies, a tightening torque of 2 Nm, and >100 mating cycles. When mated, it provides IP67/IP68/IP69/IP69K protection and is compatible with NEMA 1, 3, 4, 6P, 12 enclosures. Operating temperatures span -40 °C to +90 °C static and +5 °C to +90 °C flexible, with installation temperatures from -10 °C to +90 °C; minimum bending radii are static ≥5× and dynamic ≥10× the cable diameter. Special features include TC-ER rated construction, Sunlight and Oil resistance, -40 °C cold bend rating, UL 1685 FT4, UL 1100, CSA FT1/FT4, and flame-rated construction, with approvals UL 2237, CE, UKCA, and RoHS. Commonly used in PLC control panels, motor controls, conveyors, and industrial machinery; maintenance teams, OEM machine builders, and system integrators rely on this cordset for equipment replacement, retrofits, and production-line expansion.
