Bernstein ENK-UV15Z VTU Limit Switch

The Bernstein ENK-UV15Z VTU is a plastic-bodied, IP65-rated safety switch with a key-operated VTU interlock head, built for reliable guard-door interlocking in industrial environments. It offers a two NC plus one NO contact configuration (NC x2 + NO) for safety circuits, and is rated for Ui 400 V AC with a rated operating voltage Ue of 240 V, suitable for AC-15 usage at 240 V. The device provides a conventional thermal current Ith of 5 A and is protected by a 6 A gG fuse for short-circuit protection. Its enclosure and cover are PA 6 (UL-94-V0), with a cable entry of M20 x 1.5 and DIN EN 50013 conformity for wiring designation. Dimensions run around 40 x 130.5 x 40 mm and the unit weighs roughly 216 g, making it compact enough for integration into standard safety-gate assemblies. Operable across temperatures from -30 to +80 C, the VTU actuator supports adjustable head positioning for horizontal or vertical actuation with 45-degree increments, enabling flexible installation around guards and access points. The ENK-UV15Z VTU is part of Bernstein’s ENK safety-switch family and is compatible with replacement actuators such as 3911702228, allowing for long-term maintenance without replacing the entire switch. This configuration is well-suited for monitoring doors, flaps, and guard safety in automated systems where a robust, galvanically isolated changeover contact is required.
