Description
Allen Bradley Guardmaster Sensaguard 440N RFID Non-Contact Safety Switch
Optimise your safety system and establish exceptional security for your machine guard with the Sensaguard RFID rectangular non-contact safety switch by Allen Bradley Guardmaster.
The Sensaguard safety switches have advanced latest generation Radio Frequency Identification technology for coding and inductive technology for sensing, making them highly tamper resistant and dependable. They feature a wide sensing range and tolerance to door misalignment. Designed to be installed on machine guard doors, these non-contact switches offer a superior level of security and protection to reduce risk of injury, damage to equipment, and overall downtime. The Sensaguard range is perfectly suited to meet a wide range of industrial applications.
Features and Benefits:
• Highly tamper-proof due to secure RFID sensing
• No dedicated controller is required
• Can be connected in series with other safety components (light curtain, E-stops, key interlock switches)
• LED is located on the switch for door status and fast diagnostics
• High IP69K environmental protection rating
• 3 PNP outputs (including 1 auxiliary)
• Multiple sensing directions offers greater flexibility
• Highly reliable due to short-circuit and over-voltage protection
• Uses the standard proximity brackets

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 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.
