Our Guard Locking Switches protect hazardous areas where a danger is not immediately removed after a stop request. On many machines, removing power to the motor or actuator will not immediately stop the dangerous motion. Typical applications are high inertia rotating machines, fast rotating machines, and machines where high pressure needs to be released from pneumatic valves.
The Atlas™ 5 Guard Locking Switch is a positive-mode, tongue-operated interlock switch. It locks a machine guard closed until power is isolated then keeps the power isolated while the guard is open. With two safety (N.C.) contacts and two auxiliary (N.O.) contacts, the Atlas 5 switch is ideal for PLC-controlled machines.
The 440G-LZ Guard Locking Switch is designed for partial body access guard doors. This switch combines microprocessor technology with an RFID coded actuator, and it features a locking bolt drive mechanism that locks only when the correct actuator is detected. With this functionality, the switch is TÜV certified to Ple, Cat. 4 (EN/ISO 13849-1) which is the highest level of safety for guard door position and lock monitoring.
The 440G-MT solenoid switch is a positive-mode, tongue-operated guard locking interlock switch that locks a machine guard closed until power is isolated while the guard is open. The guard may only be opened when a signal is applied to the internal solenoid which releases the lock mechanism.
The TLS-GD2 Guard Locking Switch is a positive-mode, tongue-operated interlock switch. It locks a machine guard closed until power is isolated then keeps the power isolated while the guard is open. The TLS-GD2 has three safety (N.C.) contacts and two auxiliary (N.O.) contacts.
The TLS-Z GD2 Guard Locking Switch is an interlock switch that has a uniquely coded RFID door sensor with inductive door position sensing technology. This switch can detect if an actuator key breaks or becomes separated from its door mounted position. Built with the same solid-state technology as the TLS GD2, this switch supports the highest level of safety – Performance Level “e” (Ple) to EN ISO 13849-1.
