Experience superior security for your machine guard door and ensure maximum personnel safety with the 440N-Z2NRS1B MC1 Magnetic Safety Switch by Allen Bradley Guardmaster. This magnetically coded non-contact switch combines several magnetically sensitive elements which must be activated in a specific order to work correctly, helping to minimise downtime, reduce risk of injury to machine operators, and keep your processes running seamlessly.

The 440N-Z2NRS1B Magnetically Coded Safety Interlock Switch has 2NC magnetically operated reed switches and a 10m cable. The housing material is comprised of moulded ABS plastic, in red. It is fully protected against ingress of dust and is durable against temporary immersion in water, with an environmental protection rating of IP67 (NEMA6P). It has an operating temperature range of -10 to +55°C (+14…+131 °F). The MC1 has a sensing distance of 8mm (make) and 15mm (break). This versatile sensor is easy to install due to its moulded-in brackets and small size. For high-risk applications a control unit is used with a single sensor to provide a high-integrity system. For other applications, multiple sensors (including mechanical switches) can be connected.

Non-contact safety interlock switches improve safety for personnel by isolating the power supply to machinery when the guard door is released. This reduces the risk of injury to machine operators by preventing dangerous machine processes from running while the barrier is open.

• Magnetic coded sensing for superior security
• Non-contact actuation ensures less wear-and-tear and longer service life
• High tolerance to safety guard door misalignment
• LED indication for rapid troubleshooting and door status indication
• Designed for use with specified controllers

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, Rockwell Automation, are experts in machine safety devices and have an exceptional range to help you find your ideal solution.
