The TZK Series is designed for machines/work cells where access to a hazardous work area must be controlled until safe conditions exist. Their solenoid-latching feature permits locking a machine guard until dangerous conditions, which may exist immediately after removal of power, have abated. Solenoid-latching may be controlled by a time delay, motion detector, position sensor or other suitable component.

The unit's contact arrangement permits the prevention of a machine restart until the guard is closed and in the locked position.

Each unit is supplied with a 1/2" NPT conduit adaptor.

Features & Benefits:

• Solenoid-locking design … controls access to hazardous areas until safe conditions exist.

• Highly tamper-resistant … difficult to defeat with simple tools, tape, bent wires, etc. Reduces liability exposure.

• "Positive-break" NC contacts … ensure circuit interruption upon key removal.

• Watertight design … meets IP67 environmental sealing requirements.

• Positive locking … integral mechanical interlock prevents solenoid latching until actuating key is fully inserted.

• High-strength steel actuator key … tolerates mechanical abuse without damage.

• Rugged, corrosion-resistant housing … tolerates the most hostile environments.

• Available in "solenoid-locking" and "solenoid-unlocking" models … for application versatility.

• Optional "floating" actuator key … tolerates up to 5mm of guard misalignment without damage.

• Meets rigid safety agency standards … IEC, BG (UL and CSA pending)

• Rotatable actuating head … four user-selectable 90° positions for installation flexibility.

• Funnel entry … forgiving of minor guard misalignment.

• Optional spring-loaded actuator keys … tolerates axial misalignment of guard.

• Built-in key entry dust cover … prevents ingress of dirt and dust when key is removed.
