Use this safety interlock switch from Rockwell Automation's Allen Bradley range to improve workplace safety by preventing tampering. This simple-to-install switch is commonly mounted to the leading edge of a gate used to guard machinery, restricting access during operation. It can also shut off a machine's power in hazardous situations to prevent injury or damage to your equipment. The housing of the unit is made of glass-filled PBT (polybutylene terephthalate), which has high mechanical strength and resistance to high temperatures. This makes it a good choice for use in demanding industrial conditions. For added safety, the switch comes equipped with a stainless-steel key to prevent unauthorised interference.

• Wide operating temperature range of -20°C to +80°C for use in demanding environments
• Threaded female M20 type for secure connection
• Rotatable head with four actuator entry points for maximum versatility
• IP67 (ingress protection) rating means the unit is dust-tight and water-resistant

• CE (Conformité Européenne)
• UL (Underwriters' Laboratories)
• TÜV (Technischer Überwachungsverein)
• CCC (China Compulsory Certification)

• BBM (Break Before Make) action switch – opens the first set of contacts before closing new contacts
• Self-ejecting tamper resistant actuator that operates only when mounted to the guard
• Standard type actuator and rotatable head which allows four possible actuator entry points
• Resilient housing material comprised of glass filled PBT
• Forced guided contacts
• IP67 rated, ensuring durability against wet environments and no ingress of dust

Thanks to its compact dimensions of 95 (length) x 32 (width) x 52mm (depth), this switch is ideal for use in setups where space is limited.

This device can be used with GuardLink, a new safety 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.

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.
