Allen Bradley Guardmaster 440K Safety Interlock Switch, 2NC, Keyed Actuator Included, Glass Filled PBT

The 440K-T11303 Trojan T15 Safety Interlock Switch offers essential reliability, ease-of-use, and greater durability for your machine guard door to keep your processes running as smoothly and safely as possible.

This compact unit is a universal tongue actuated safety interlock switch which features 2 entry slots. The head can be conveniently rotated to offer up to 4 actuator entry options, allowing application flexibility to suit your requirements. The head can be moved only by releasing the cover screws. The Trojan T15 safety switches are designed to be fixed onto hinged, sliding and lift-off machine guards and offer superior protection for equipment and operators.

The 440K-T11303 standard model Trojan T15 tongue interlock switch has 2NC (Normally Closed) safety contacts. The housing material is red for high visibility and is comprised of resilient UL approved glass filled polybutylene terephthalate. It is water-tight and dust-proof, giving it a high ingress protection rating of IP67. This safety switch also has a standard type actuator made of robust stainless steel for high durability. It has M20 conduit entry and a voltage rating of 600VAC and 600VDC. Operation of the interlock unit is simple – the specially profiled key must be permanently fixed to the guard door and can then be inserted into the switch.

• Direct opening action contacts and tamper-resistant mechanism
• Dual key entry slots and rotatable head to allow up to 4 actuator entry points
• 30N actuator retention force for improved stability and security
• Compact size, offering greater versatility - 75 x 52 x 32mm
• 3 M20 conduit entries
• Easy installation
• Durable and reliable due to high IP67 environmental protection rating

Note: Units are supplied with a standard actuator, other actuators may be ordered 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 equipment. They can also be used to monitor the status of the 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.
