ADDITIONAL DESCRIPTION Product DetailsAllen Bradley Guardmaster 440N-G02157 Non-Contact Magnetic Safety SwitchMake personnel safety and machine protection the highest priority in your workplace with the Ferrogard 440N-G02157 Magnetic Safety Switch in stainless steel, 24 V dc, 2NC by Allen Bradley Guardmaster. This non-contact switch is designed for use on machine guards and gates to limit access to hazardous areas where dangerous machinery is in motion. When the safety guard is opened and the magnetic actuator is released from the switch the NC safety contacts will open, resulting in the immediate isolation of supply power to the machine.This device has high tolerance to door misalignment, non-contact reliability and robust stainless-steel housing to protect against unintended impacts. The FRS 14 sensors and actuators have slim housings, making this safety switch perfect for narrow mounting areas. These Ferrogard switches have greater flexibility of mounting options as they have two active sensing faces. Unlike other magnetic switches, they have protected safety contacts so that they do not fail in case of danger. They also have internal non-resettable overload protection on the safety contact. Contacts are fully sealed to IP67 (NEMA 6P), making this non-contact switch durable against frequently wet environments. With simple set-up and alignment, this non-contact switch will decrease your installation costs and keep your production line running smoothly.Allen Bradley Guardmaster have an extensive range of high-quality, cost-effective machine monitoring and safety solutions, which are specifically designed to minimise downtime and offer high levels of protection for machine operators. Their products are manufactured to global standards for stability and reliability to provide you with exceptional security, efficiency, and flexibility in the workplace.Note: This safety 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, whilst providing real-time diagnostic information over an Ethernet IP. This makes it simple to identify the location of the device that has tripped the safety system, thus reducing downtime and improving the machines overall efficiency.

They also cannot be easily tampered with or manipulated. They are often used in industrial applications, such as machine monitoring and guarding in factory production lines, and are often used with sliding, hinge and lift-off doors. Allen Bradley Guardmaster is a world leading brand for machine safety components and their products are rigorously tested to provide you with maximum security.
