Product Overview

Allen Bradley Guardmaster 440G-T27121 Solenoid Interlock Switch

Gain superior protection for personnel and keep your machine guard door secure with the TLS-1-GD2 440G-T Solenoid Interlock Safety Switch, Power to Unlock, 24V ac/dc, by Allen Bradley Guardmaster.

This device is a positive mode, tongue operated interlock switch that ensures guards are safely locked while machinery is in motion, and keeps power isolated when the guard is open. This reduces the risk of personnel entering a hazardous area. This cost-effective switch is perfect for use with machines which do not stop instantly, or which may be damaged by interference while in motion. The secure interlock mechanism is released only when an external signal is applied to the internal solenoid, which then allows the safety barrier to be opened.

The 440G-T27121 has power to unlock functionality and an operating temperature of -20 to +60 °C (-4…+140 °F). It has a supply voltage of 24VAC/DC, M20 conduit entry, thermal current of 10A, and rated insulation voltage of 500V. It features 2NC Safety Contacts, 1NO Auxiliary Contact, and 1NC/1NO Solenoid Contacts. The housing material is comprised of UL approved glass-filled PBT and this guard locking switch is fitted with a stainless-steel actuator guide to protect the unit from actuator damage due to wear-and-tear and poor gate alignment. It is suitable for use with PLCs.

Allen Bradley Guardmaster have an extensive range of machine monitoring and locking components that are built to global standards for quality and reliability. Their affordable solutions are expertly designed to meet every requirement and improve protection, efficiency, and productivity in the workplace.
