Product Details

Allen Bradley Guardmaster 440K-T11305 Trojan T15 Safety Interlock Switch

Make protection of personnel the highest priority in your workplace and keep your machine processes secure with the 440K-T11305 Trojan T15 interlock switch by Allen Bradley Guardmaster. 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 440K-T11305 Trojan T15 safety switch includes a standard type stainless-steel actuator, offering superior durability and longevity. It has 1NC safety contact, 1 NO auxiliary contact, and convenient M20 conduit entry. This standard model safety switch has a high ingress protection rating of IP67, which ensures that it is dust-tight and can withstand washdown environments. The housing material is comprised of resilient UL approved glass filled polybutylene terephthalate. The housing is also red to provide excellent visibility of the unit. The Trojan T15 switches are specifically designed to be fixed onto hinged, sliding and lift-off machine guards and offer enhanced protection for operators. It has break-before-make action and a voltage rating of 600VAC and 600VDC.
The Trojan T15 switch is operated by inserting a specially profiled key, which is permanently fixed to the door. The 440K Trojan interlock units provide cost-efficient and safe electrical interlocking of the guard to the control circuit of the machine.

How does a Safety Interlock Switch work?

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.
