For a safer and more efficient work environment give your machine guard, gate, or door an upgrade with the Ferrogard 440N Magnetic Safety Switch, 24 V dc by Allen Bradley Guardmaster.

The innovative Ferrogard range of magnetically actuated safety switches have increased tolerance to door misalignment, in addition to the reliability of non-contact switches. This device helps to protect your personnel by cutting off power to a machine which is in motion when the safety barrier is released, thereby preventing access to a hazardous area. It is designed so that the magnetic actuator is removed from the switch when the guard door is opened, which opens the NC safety contacts.

The contacts are fully sealed to meet IP68 (NEMA 6P) requirements, making them ideal for wet environments as they can withstand powerful jets of water and are dust tight. Unlike other magnetic safety switches they have protected safety contacts to ensure that they do not fail to danger and have internal non-resettable overload protection on the safety contact.

Rockwell Automation are industry experts at machine monitoring and guarding, and the extensive Allen Bradley Guardmaster range of machine safety devices has high-quality, tried and tested product solutions to meet your unique application requirements. Their safety switches are designed to improve productivity by keeping your machines running smoothly and giving your personnel the highest level of protection.

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.

Non-contact safety switches by Allen Bradley Guardmaster offer conveniently simple setup and alignment which helps to reduce installation costs, require minimal maintenance, and are long lasting. They are ideal for sliding, hinge, or lift-off machine guard doors and are often used in industrial applications, such as machine guarding in factory production lines. The risk of debris contamination is reduced due to no contact between the sensor and actuator.
