440N-A17233 MC1 Spare Actuator

Complete your MC1 safety interlock switch with the 440N-A17233 actuator and ensure total protection for your guard door and personnel.

The 440N-A17233 unit is a Spare Actuator which is designed specifically for use with the MC1 contact-free Safety Switch. This actuator part has housing made of resilient moulded ABS plastic, which is red for easy visibility.

The MC1 has a sensing distance of 8mm (make), 15mm (break). It also has an environmental protection rating of IP67, which ensures that it is fully dust-proof and can withstand temporary immersion in water.

The MC1 interlock switch is expertly designed to meet the risks of more complex modern safety guard monitoring applications. This type of safety switch combines 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 decrease risk of injury to machine operators from hazardous equipment, minimising downtime.

What are magnetically coded non-contact switches?

A non-contact switch with magnetic coding is a device used for monitoring the position of machinery 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.

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.
