Allen Bradley Guardmaster 440N Series Magnetic Non-Contact Safety Switch, ABS Housing

The 440N-A02025 Actuator from Allen Bradley Guardmaster is a replacement actuator designed for use with the Ferrogard 6, 9 and 10 non-contact safety interlock switches. This actuator is made of durable moulded ABS plastic, which is red for easy visibility. The housing is slim to allow use in narrow mounting areas, allowing greater application flexibility.

The Ferrogard FRS 6, 9 and 10 units are magnetically actuated contact-free interlock switches which can be installed on machine guard doors to limit access to hazardous areas. Due to their magnetic sensing this type of switch provides a high tolerance to guard door misalignment, giving you optimal reliability.

With these interlock switches the NC safety contacts are opened when the magnetic actuator is withdrawn from the switch. This isolates power to the machinery, ensuring that it cannot run while personnel have physical access. The Ferrogard units are cost-effective non-contact safety switches which offer greater protection for personnel and equipment. The Ferrogard switches are perfect for wet environments where wash-downs are regular. They also feature 2 active sensing faces to offer different mounting options.

• Red moulded ABS plastic housing
• Operating distance for safety contacts: make 12mm and break 23mm
• Operating temperature range is between -10°C and 65°C
• M4 mounting
• Suitable for use in narrow mounting areas due to slim housings
• 2 active sensing faces

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 guard doors to restrict access to unsafe areas. They are often used in industrial environments such as factory production lines on sliding, hinged and lift-off barriers.

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.
