Allen-Bradley 440G-A27011 GD2 standard actuator for Bulletin 440G tongue-style safety interlock switches. This actuator provides a mechanical interface to open safety contacts when a guard door is opened. Designed for standard-duty applications, it supports safety circuits meeting Category 4, PLe, and SIL 3 requirements as part of the Guardmaster safety system.

Product Details

Allen Bradley Guardmaster 440G-A27011 GD2 Standard Actuator

Complete your safety interlock switch and gain superior protection for machinery and personnel with the 440G-A27011 GD2 Actuator by Allen Bradley Guardmaster.
The 440G-A27011 unit is a Standard Actuator which is designed for use with the TLS-GD2 safety interlock switch. It is made of robust stainless-steel to provide superior durability.
This specially profiled actuator should be permanently attached to the leading edge of the guard door. The safety switch is operated by inserting the actuator into the switch. This type of actuator is highly suitable for use with interlock switches for hinged, sliding, and lift-off safety barriers.

Features and Benefits:

Standard GD2 Actuator
Accessory for use with TLS-GD2 model interlock switch
Tough and reliable
Made of stainless-steel
The GD2 actuators are dedicated actuators for GD2 models only. They are not suitable for use with standard models.

What are Safety Interlock Switches?

Safety Interlock Switches are locking devices which can be used to monitor the position of a machine guard door and turn off the power supply when the safety barrier is released. They can also be used to keep a guard securely locked when machinery is running. This helps to prevent personnel from accessing a hazardous area where machinery may be in motion and minimises risk of injury or equipment damage. Interlock switches are often used for industrial applications.

What is a Safety Interlock Actuator?

The actuator is a separate component which is usually inserted into the switch to enable the locking mechanism to work. It forms a key part of the overall safety interlock unit. Different types include: 90º, Flat, Standard, Semi-Flexible, Fully Flexible, and Specialty.
Rockwell Automation is a global leader in industrial automation and digital transformation, and brings smart manufacturing to life. With a long legacy of creating Allen-Bradley integrated control and information solutions, we help make you as productive as possible. Our portfolio of sensing, safety and motor control products can support your move towards smart machine applications. Allen-Bradley IO-Link sensors are data-enabled and communicate with all field buses, providing diagnostic and health information about the device before a machine stops, and enabling quick production changeovers through fast parameter downloads from PLCs into the device. This reduces machine downtime and increases manufacturing OEE. For safety components, products with built-in diagnostics simplify the set-up of the smart device, and reduce maintenance, leading to a more efficient, machine data-driven approach.
