Allen Bradley Guardmaster 440N Series Magnetic Non-Contact Safety Switch, Plastic Housing, 2NC, 3m Cable

Upgrade the safety of your machine guard with the MC1 440N-Z2NRS1A Magnetic Non-Contact Safety Switch by Allen Bradley Guardmaster. This magnetically coded non-contact interlock switch combines several magnetically sensitive elements which must be activated in a specific order to work correctly. The MC1 switch is designed to meet the risks of more complex safety guard monitoring applications. It will limit personnel access to hazardous areas where machinery is in motion by removing power to the motor when the barrier is opened.

This sensor is exceptionally versatile and simple 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. It has high tolerance to door misalignment due to its wide sensing range, ensuring enhanced stability and security for your equipment. It has simplified set up and alignment to help decrease installation costs. This device also has a rating of IP67 (NEMA 6P), making it perfectly suited to wet environments where machines are regularly washed down, and it is also dust-tight.

Allen Bradley Guardmaster aim to maximise protection, efficiency, and productivity in your workplace with their wide range of safety devices for machinery. With their high-quality products recognised for excellence and innovation across the globe, you can be sure to find a flexible and secure solution to meet your requirements.

A magnetically coded non-contact switch is a device used for monitoring the position of machine safety barriers. They are typically used in industrial environments. It uses a magnetically-actuated reed contact and a specially-coded actuator. When the barrier is opened the contacts will either open or close due to the magnetic force interrupting the circuit. As there is no contact between the sensor and actuator they take less wear, are resistant to shocks and vibrations, and are highly tamper-proof, which gives them a long service life. They are often used for sliding, hinge, and removable gates.
