Allen Bradley Guardmaster MC1 440N-Z2NRS1C Magnetic Safety Switch

The 440N-Z2NRS1C MC1 Non-Contact Safety Switch by Allen Bradley Guardmaster offers superior protection for personnel around dangerous machinery by combining several magnetically sensitive elements which must be activated in a specific order to work correctly and allow the safety barrier to open. This improves guard door security and helps to reduce risk of injury to machine operators, minimising downtime. The MC1 switch is designed to meet the risks of more complex safety guard monitoring applications.

This versatile magnetically coded sensor has simple installation due to its small size and moulded-in brackets. 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 switches are a highly dependable method of securing machine safety guards as they isolate the power supply to the machine when the gate is released, preventing machine operators from unsafe access to machinery which may be in motion.

The 440N-Z2NRS1C MC1 Switch has 2NC Magnetic Reed Switches and a 6 in Pigtail, 4-Pin Micro (M12) connector. The housing material for this switch is comprised of moulded ABS plastic, in red. It has an operating temperature range of -10°C and 55°C. The MC1 has an operating distance of 8mm (make), 15mm (break) and a switching current of 24V DC at 200 mA. It is protected to IP67, making it highly suitable for use in wet environments as it can withstand temporary immersion in water and is also dust-tight.

Features and Benefits:

• Designed for use with specified controllers
• Magnetic coded sensing for superior security
• Non-contact actuation ensures less wear-and-tear and longer service life
• High tolerance to guard door misalignment
• Perfect for use in wet environments due to IP67 rating

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.

What are magnetically coded non-contact switches?

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.
