440G-LZ GUARD LOCKING SWITCH 24VDC 2XPNP 1XPNP RFID

The ALLEN-BRADLEY 440G-LZS21STRH is a guardlock switch that provides power-to-release interlocking for safety doors and guards. Designed as a 440G-LZ series device, it combines two normally-closed safety contacts with one normally-open door auxiliary contact and solid-state outputs to monitor guard position and control power release. The standard coded actuator and plastic housing make it suitable for machinery access panels where defined actuator alignment is needed, while the 8-pin DC quick-disconnect connector simplifies wiring and replacement. Ideal for industrial safety applications, this guardlock switch is used by maintenance technicians and safety engineers to secure access and manage machine shutdowns during servicing.
