Allen Bradley 440N Series Magnetic Non-Contact Safety Switch, 24V dc, Plastic Housing, NC, 2m Cable

Enhance the safety and security of your machine guards and provide essential protection for personnel with the Ferrogard FRS, 6 9 and 10 by Allen Bradley Guardmaster. These magnetically actuated non-contact safety switches are specially designed to be installed on guard doors and work by immediately cutting off the power supply to a machine when the safety guard or gate is opened, thereby restricting unsafe access for personnel to a hazardous area. The magnetic actuator is removed from the switch when the door is released, which then opens the NC safety contacts.

They offer reliability and a high tolerance to misalignment due to their large sensing field. These switches are dust-tight and are highly suitable for wet environments as they are sealed to IP67 (NEMA 6P). With two active sensing faces, they offer a wider range of mounting options for your convenience. This switch is moulded in ABS plastic with a slim rectangular housing, making it perfect for narrow mounting areas.

• Slim housings, well suited to narrow mounting areas and two active sensing faces permitting more flexible mounting options
• Non-contact actuation, which allows the machine guard to be opened immediately
• Operating distance for safety contacts: make 12mm; break 23mm
• Operating temperature range: -10°C to +65°C
• M4 mounting
• Cat. 1 Device per EN954-1 Dual channel interlocks suitable for Cat. 3 or 4 systems

Approvals: CE Marked for all applicable directives and cULus,

Standards: EN954-1, ISO13849-1, IEC/EN60204-1, NFPA79, EN1088, ISO14119, ANSI B11.19, AS4024.1.

Looking for a reliable safety device for your guard doors? Turn to this Allen Bradley switch from Rockwell Automation. It's a magnetically actuated safety switch that works by immediately cutting off the power supply to a running machine when the guard doors are opened. Use it to prevent accidents and improve workplace safety. The sensor is housed in a robust ABS (acrylonitrile butadiene styrene) material that provides reliable impact and corrosion resistance for long-term performance. This switch is commonly used in manufacturing environments to prevent unsafe access to moving machine parts.

• Compact dimensions of 84 (length) x 19 (width) x 16mm (depth) to fit into small spaces
• Overload protection to ensure electrical safety
• Short break distance of 23mm for speedy actuation when the door is opened
• IP67 (ingress protection) rating for complete protection against dust and resistance to water

• BS EN 61340-5-1:2007 (British Standard)
• ANSI/ESD S20.20:2014 (American National Standards Institute)
• UL (Underwriters' Laboratories)
• CE (Conformité Européene)
• CSA (Canadian Standards Association)

You can use this versatile unit for a wide variety of industrial guard types, including hinge-type doors, sliding doors and lift-off hinge doors.

The 400N series safety switches have simplified set up and alignment to decrease your installation costs. All Ferrogard switches have internal non-resettable overload protection on the safety contact, as well as protected safety contacts to help ensure that they do not fail to danger, providing your machine processes with a higher level of stability.
