440G SOLENOID GUARD LOCKING SWITCHES

The ALLEN-BRADLEY 440G-TZS21UTRH is a guardlock safety switch designed to control access by providing power-to-release locking with a unique coded actuator. This guardlock switch features two normally closed safety contacts plus one normally closed door auxiliary contact and uses solid state contacts for reliable signal handling. The TLS-Z style with plastic housing and an 8-pin DC quick-disconnect simplifies wiring and integration into machine safety circuits. Suitable for industrial safety interlocking applications, it prevents door opening until control power is applied and is ideal for machinery access control where coded actuator recognition and compact, durable plastic construction are required.
