Allen Bradley Guardmaster 440N Series Magnetic Non-Contact Safety Switch, 250V ac, Stainless Steel Housing, NC, 2m Cable

Improve protection for personnel and provide essential safe-access to machinery with the Ferrogard Non-Contact Safety Switch in Stainless Steel, 2m Cable, by Allen Bradley Guardmaster. This unit offers superior security and stability as it combines the reliability of non-contact switches with a high tolerance to door misalignment.

The 440N-G02154 magnetically actuated switch has 1NC Safety and 1 NC auxiliary contacts, a supply voltage of 250 V ac at 2A current, and a 2m cable. It has robust Stainless Steel FRS13 rectangular housing which suits narrow mounting areas. It is designed to be installed on machine guards and doors and has 2 active sensing faces. The operating distance is: make 12 mm, break 23 mm. This switch is ideal for wet environments as the contacts are environmentally sealed to IP67 (NEMA 6P), ensuring that they are fully dust-tight and can withstand temporary immersion in water. All Ferrogard safety switches have internal non-resettable overload protection on the safety contact and protected contacts to help ensure that they do not fail to danger, unlike some magnetic switches.

How it works: The magnetic actuator is withdrawn from the switch when the safety barrier is released. This opens the NC safety contact which then isolates power to the machine. This ensures that machinery cannot run while the guard is open, ensuring that personnel cannot access a hazardous area.

• Two sensing faces
• High switching current
• High tolerance to misalignment due to large sensing field
• Non-contact actuation which ensures long service life due to less wear-and-tear, also allows simple set-up and the guard door can be opened immediately
• Sealed to IP67 (NEMA 6P) – fully protected against dust ingress and can withstand temporary immersion in water
• Enhanced durability due to Stainless Steel housing, which protects against inadvertent impacts, housing is slim for application flexibility

Note: This safety device can be used with Guardlink, a new safety linking technology from Allen Bradley GuardMaster. Guardlink simplifies and reduces the connection time of the safety system, whilst providing real-time diagnostic information over an Ethernet IP. This makes it simple to identify the location of the device that has tripped the safety system, thus reducing downtime and improving the machines overall efficiency. For more details, please go to the Guardlink brochure.

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.
