440K-T11118 Safety-Rated Switch

The 440K-T11118 Trojan 5 tongue interlock switch by Allen Bradley Guardmaster has Make Before Break Action and includes a standard type actuator made of durable stainless-steel. It has convenient M20 Conduit entry and a maximum current of 6A. The operating temperature is -20°C to +80°C (-4°F to +176°F). Rated insulation voltage is 500V. The housing material is comprised of tough UL approved glass-filled PBT. The 440K safety switches provide cost-effective, secure electrical interlocking of the guard to the machine’s control circuit.

Features and Benefits:

• Easy installation

• Versatile switch with rotatable head to allow 4 possible actuator entry positions, for greater application flexibility

• Tamper resistant due to self-ejecting actuator that operates only when mounted to the guard

• 3 sets of contacts – 2NC Safety, 1NO Auxiliary

• Forced guided contacts

• Durable and versatile - can be used in most applications

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 applications, 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 machine safety standards. Allen Bradley Guardmaster switches are built to global standards to provide exceptional quality and reliability.
