MLZ-M Compact Guard Locking Safety Switch with RFID in a Heavy-Duty Die-Cast Housing
The MLZ-M ultra-compact RFID guard locking safety switch features a robust mirror-polished die-cast metal housing, ensuring durability and resistance to demanding environments. Measuring just 30mm in width, the MLZ-M is perfectly suited for installation on narrow machine guard rails, eliminating the need for additional mounting plates and simplifying both setup and maintenance.
With three RFID-coded entry points, the device offers flexibility in actuator approach, adapting easily to diverse guard configurations. It delivers a high holding force of 4000N, ensuring that guards remain securely locked even under substantial stress, which enhances safety integrity.
Equipped with OSSD outputs, the MLZ-M enables series connection of up to 30 units without compromising on safety. With its compact size, advanced features, and robust design, the MLZ-M is a reliable and innovative solution for machine safety applications.
