Plastic-bodied safety switch with separate actuator ENK … VTU Protection class IP 65 (pending) Designation Part number Switching diagram p Forced disconnect IEC 947-5-1 Chap. 3 Za: changeover contact is not galvanically isolated Zb: changeover contact is galvanically isolated Slow-action contact/snap-action contact Gasket inside (iw)/outside (w) The safety switch ENK ...VTU offers the optimum combination of a cost-reducing plastic-bodied housing and an actuating system for difficult industrial demands. The housing, made of glass-fibre reinforced polyamide, fulfils the demands required for isolated low-voltage switching and contact devices. Due to its pin shaped geometry, the particularly robust, separate actuator is suitable for use in tolerance-burdened protective equipment. Optional actuators, which can be adjustable or flexibly mounted, guarantee a high mechanical loading capacity. l Mounting dimensions according to EN 50041 l Integrated mounting plate made of metal l Actuation in horizontal and vertical directions l A total of 8 actuating directions possible Contact travel mm Tol. ± 0.25 mm l Safety contacts with positive break and galvanic isolation l Contacts: 1NC+1NO, 2NC or 2NC+1NO (with overlapping contacts) l Wiring space with hinged, self-locking lid l Protection class IP 65 l Radius actuator and lateral actuator optional Actuating force N Tol. ± 10% In Out Voltage max.
