Create a safer workplace and keep your machine guard secure with the 440N-G02099 Ferrogard Magnetic Non-Contact Safety Switch by Allen Bradley Guardmaster. This magnetically actuated safety switch offers peace-of-mind by providing the well-known reliability of non-contact switches along with greater tolerance to door misalignment and movement with its wide sensing field.

This Ferrogard switch is specifically designed to be installed on machine guard doors. The magnetic actuator is withdrawn from the switch when the safety barrier is released. This opens the NC safety contacts which then isolates power to the machine. This ensures that machinery cannot run until the guard is closed, and that personnel cannot access a hazardous area - reducing risk of injury.

The 440N-G02099 Ferrogard Safety Interlock Switch has 2NC safety contacts, 1NO auxiliary contact, and has a switching capacity of 24V DC, 1 A max. It features a 6-pin Micro Quick Disconnect cable and FRS21 rectangular housing. The housing is comprised of moulded ABS plastic in red. This switch is sealed to IP67, ensuring that it is fully protected against ingress of dust and can withstand temporary immersion in water. It has an operating temperature range of -10°C to +55°C (+14…+131 °F), and the operating distance for the safety contacts is 12mm (make), 23mm (break).

• High switching current
• High tolerance to safety guard door misalignment
• Non-contact actuation ensures less wear-and-tear and longer service life
• Environmentally protected to IP67 (NEMA6P)

Rockwell Automation is a global leader in industrial automation and digital transformation, and brings smart manufacturing to life. With a long legacy of creating Allen-Bradley® integrated control and information solutions, we help make you as productive as possible. Our portfolio of sensing, safety and motor control products can support your move towards smart machine applications. Allen-Bradley® IO-Link sensors are data-enabled and communicate with all field buses, providing diagnostic and health information about the device before a machine stops, and enabling quick production changeovers through fast parameter downloads from PLCs into the device. This reduces machine downtime and increases manufacturing OEE. For safety components, products with built-in diagnostics simplify the set-up of the smart device, and reduce maintenance, leading to a more efficient, machine data-driven approach.

Non-contact safety switches are highly reliable and durable. They take less wear and tear and are low-maintenance, as well as resistant to shocks and vibrations. They cannot be easily manipulated or tampered with and are ideal for use with machine guards and doors to restrict access to unsafe areas. They are often used in industrial environments, such as in factory production lines. Allen Bradley Guardmaster are industry experts in machine safety devices and have an exceptional product portfolio to help you create your ideal safety system.
