Product Description
The Allen-Bradley 440G-TZS21UPLH Guard Locking Switch, part of the Guardmaster TLS-ZR-GD2 line, is a 24V DC safety interlock device with 1 PNP auxiliary and 2 PNP safety contacts, designed for high-performance guard locking systems. It features a flexible actuator for easy mounting, integral microprocessor technology, 2 OSSD solid-state outputs, logic-level locking/unlocking, and a unique-coded RFID door target that shuts down the OSSD outputs if the actuator key is missing or broken. Its OSSD outputs can be series-connected with other compatible safety components, and a stainless steel actuator guide protects against damage from guard wear or misalignment.
Is Your Device Showing These Signs?
The Allen Bradley 440G-TZS21UPLH safety switch commonly experiences issues such as actuator misalignment preventing proper interlock, damaged or worn internal safety contacts leading to circuit failure, and cable damage affecting signal integrity. Technicians address these problems through precise actuator adjustments, replacement of faulty contact blocks to restore safety circuit functionality, and cable repair or replacement to ensure consistent signal transmission. Troubleshooting often involves continuity testing and voltage checks to pinpoint the source of the malfunction and confirm proper operation after maintenance. Environmental factors, such as excessive dust or moisture, contribute to switch degradation and require preventative measures.
