2. Safety interlock switch:

Our safety interlock switch is a safeguard that monitors the position of a guard or door. You can use them to cut power, control access, and prevent machines from starting when guards are open. Contains:

 

Protection lock switch:

Bulletin 440G Series Guard Lock Switches Our guard lock switches provide protection for hazardous areas that cannot be removed immediately after a stop request. On many machines, removing power to a motor or actuator does not immediately stop dangerous motion. Typical applications are high inertia rotating machines, fast rotating machines, and machines that require high pressure relief from air pressure valves.

The Atlas™ 5 Guard Lock Switch is a positive mode tongue type interlock switch. It latches machine guards until power is isolated, then keeps power isolated while the guard is open. With two safety (normally closed) contacts and two auxiliary (normally open) contacts, the Atlas 5 switch is suitable for PLC controlled machines.

The 440G-LZ protective lock switch is mainly used for protective doors involving partial body contact. The switch uses microprocessor technology with an RFID-encoded actuator. It also features a detent drive mechanism that only locks when the correct actuator is detected. Due to its complete functionality, the switch is Ple, Cat4 (EN/ISO 13849-1) certified by TÜV for the highest security level of guard door position and lock monitoring.

The 440G-MT Solenoid Switch is a positive-mode tongue-type protective interlock switch that latches machine guards until power is isolated, and then maintains power isolation while the guard is open. The guard can only be opened when a signal is applied to the internal solenoid that releases the locking mechanism.

The TLS-GD2 guard locking switch is a positive mode tongue type interlock switch. It latches machine guards until power is isolated, then keeps power isolated while the guard is open. The TLS-GD2 has three safety (normally closed) contacts and two auxiliary (normally open) contacts.

The TLS-Z GD2 Guard Lock Switch is an interlock switch featuring a uniquely coded RFID door sensor using inductive door position sensing technology. This switch detects if the actuator key is broken or detached from its door mounting position. Built using the same solid state technology as the TLS GD2, this switch supports the highest level of security - Performance Level "e" (Ple) in accordance with EN ISO 13849-1.
