Allen Bradley Guardmaster Centurion 440K-B04026 Safety-Rated Interlock Switch


This 440K-B04026 guard locking switch is positive mode and thumbwheel operated, and is ideally suited for use with simple machines which have short, constant run-down times due to the 20 second delay before the guard door can be opened. It is important that the unit is installed and operated correctly to ensure that the retractable shaft is not extended when the guard is open.


This durable safety switch has Break Before Make Action (opens the first set of contacts before closing new contacts). Actuator type is Left Hand. It features M20 Conduit Entry and has an operating temperature of -25°C to +80°C. Thermal current rating is 10A and it has a rated insulation voltage of 500V.


Features and Benefits


• 2NC Safety Contacts, 1NO Auxiliary
• Easy to operate and simplified installation for your convenience
• Perfect for use in heavy duty applications due to robust die-cast metal alloy housing material
• Locks the guard firmly closed until the operator manually rotates the thumbwheel, retracting the shaft from the guard door
• 15-20 second time delay before the guard can be released
• Isolates power to machine when the guard door is open, minimising risk of injury to personnel

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