Allen Bradley Guardmaster 440K Safety Interlock Switch, 2NC/1NO, Keyed Actuator Included, Glass Filled PBT

Enhance your machine guard and improve protection for machine operators with the 440K-T11338 Trojan 5 GD2 Safety Interlock Switch by Allen Bradley Guardmaster.

This tongue interlock switch is perfectly suited for use with sliding, hinged, and lift-off machine guards and can be fitted to the leading edge of the door. The Trojan 5 switches have dual key entry slots. This safety switch can be operated by inserting a specially profiled key, which is attached the guard door.

The 440K-T11338 Trojan 5 Safety Switch has 2NC safety contacts, 1NO auxiliary. This GD2 unit has break-before-make action and includes a robust stainless-steel fully flexible actuator. It features a tough metal head to ensure high resilience against impacts and greater longevity, making it ideal for more demanding applications. The housing is also made of durable UL approved glass-filled PBT and is red for easy visibility. It has a high ingress protection rating of IP67, ensuring that it is dust-proof and water-tight. This interlock switch has a voltage rating of 240VAC and 24VDC and M20 conduit entry.

• 3 Sets of contacts
• Versatile - Can be used in most applications
• Tough stainless-steel head provides superior durability against impacts
• IP67 rated, making it ideally suited for wash-down environments
• Forced guided contacts and easy installation

Note: Stock no. 792-3089 is supplied with an alignment guide with a fully flexible actuator, stock no. 873-2203 is supplied with a GD2 standard actuator, for stock no. 351-3975 actuators must be purchased separately.

This device can be used with GuardLink, a new linking technology from Allen Bradley Guardmaster. GuardLink simplifies and reduces the connection time of the safety system while providing real-time diagnostic information over Ethernet IP. This simplifies the identification of the location of the device that has tripped the system. Thus, it reduces downtime and improves the overall efficiency of the machines. For more details, please refer to the GuardLink brochure.

Safety interlock switches work by securely locking guard doors and gates, preventing unsafe access to hazardous areas where machinery may be in operation. This helps to decrease 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 applications, such as safeguarding factory production lines. They can vary in lock type, maximum current and voltage, and housing material. These interlock switches are specifically designed to meet high standards of protection.

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.
