IEC EN 60947-5-1, IP65, approval from the professional association GS-ET-19, world market device, actuator for electromagnetic door locking, By reliably securing and locking protective doors, the LS-ZBZ increases the safety standard in personal and process protection. The LS-ZBZ works according to two functional principles: with magnetic force or spring force locking. The spring force locking is ideal for increased personal protection. This means that every door remains securely closed even in the event of a power failure. The protective cover can be opened in an emergency using an auxiliary release. Magnetic force locking devices are used in personal and process protection. The protective cover is locked when the voltage is applied; in the event of a power failure, the protected area can be reached directly. With separate signaling of the door position, suitable for electronics in accordance with IEC/EN 61131-2
