The 440G-T27134 is part of Allen Bradley's Guardmaster Safety Relays series and functions as a guard locking interlock switch. Designed to operate within a supply voltage of 24 VAC or DC, it features two safety contacts configured as normally closed (N.C.) and one auxiliary contact that is normally open (N.O.). This configuration ensures a secure and reliable operation for safety-critical applications.

With a rated insulation voltage of 500 volts, this switch is built to handle demanding electrical environments. The power-to-release locking mechanism allows for safe disengagement under controlled conditions, while the impressive maximum holding force of 2000 N ensures that the guard remains in place until it is safe to release.

For environmental resilience, the enclosure is rated IP 67, providing complete protection against dust and the capability to withstand temporary immersion in water. This product is effective within a temperature operating range of -20 degrees Celsius to +60 degrees Celsius, making it suitable for diverse conditions.

Constructed from UL Approved glass-filled PBT, the housing material ensures durability and longevity. Although the actuator is not included as part of the package, an actuator made from stainless steel can be used to complete the interlock mechanism. The combination of these features makes the 440G-T27134 an excellent choice for enhancing safety in machinery and equipment operation.
