Allen Bradley Guardmaster Trojan 5 GD2 Safety Interlock Switch for Demanding Applications

Safeguard personnel and keep your machine processes running smoothly with the Trojan™ 5 GD2 Interlock Switch by Allen Bradley Guardmaster. These reliable interlock switches are expertly designed for use in demanding applications, as they feature a robust stainless-steel head which provides superior resistance to wear and tear, extending service life.

These switches can be fitted to the leading edge of hinged, sliding and lift-off machine guard doors and are universal tongue (or key) operated interlocking devices. They feature dual key entry slots and rotatable heads, which can be adjusted by releasing the cover screws. They offer four actuator entry points, providing greater functionality. These cost-effective switches have 3 sets of contacts and are simple to install.

The Trojan 5 GD2 can be operated by inserting specially profiled stainless-steel key, which is attached to the leading edge of the guard door. This switch electrically interlocks the control circuit of a machine to its guard, ensuring that power is isolated when the barrier is open and minimising risk of injury.

Allen Bradley Guardmaster provide a wide range of reliable machine safety switches and components to deliver cost-effective solutions for a variety of industrial applications, giving you maximum flexibility and control.

What is a Safety Interlock Switch?

A safety interlock switch is a device which keeps guard doors and gates securely locked to prevent access to areas where dangerous machinery may be in operation, minimalising the risk of injury to personnel and damage to machinery. They can also be used to monitor the status of the machine guard, and to ensure that machinery cannot start up or run while the guard door is open. They are often utilised in industrial settings, such as safeguarding factory production lines. They can vary in lock type, maximum current and voltage, and housing material. Safety-rated interlock switches are specifically designed to meet high safety standards. Allen Bradley Guardmaster switches are built to global standards to provide exceptional quality and reliability.

Note: This device can be used with Guardlink, a new safety linking technology from Allen Bradley Guardmaster. Guardlink simplifies and reduces the connection time of the safety system, whilst providing real-time diagnostic information over Ethernet IP. This makes it simple to identify the location of the device that has tripped the system, thus reducing downtime, and improving the machines overall efficiency.
