Allen Bradley Guardmaster 440K Safety Interlock Switch, Keyed Actuator Included, Metal, Keyed

This safety interlock switch from Rockwell Automation's Allen Bradley range works by cutting off power to a machine in hazardous situations. It features a retractable interlock shaft that prevents access to the machine during operation, preventing injuries and equipment damage. The switch also has a 15 to 20-second time delay, making it suitable for use with machines that need extra time to shut down. A robust die-cast metal-alloy housing means you can use this switch in heavy-duty applications. This material also provides good resistance to heat for use in hot environments. To reset the switch and resume machine operation, simply rotate the thumbwheel until the shaft retracts from the guard door.

• M20 threaded connection for a secure fit

• CE (Conformité Européenne)

Allen Bradley Guardmaster provide a wide range of reliable machine safety switches and components to deliver cost-effective solutions for a variety of industrial applications, giving you maximum flexibility and control.

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

This switch offers a mechanical life of up to 1,000,000 operations, so you can be sure of long service.
