Description
Allen Bradley Guardmaster Sensaguard 440N RFID Cylindrical Non-Contact Safety Switch
Optimise your guard door and improve machine safety with the Sensaguard 440N RFID Cylindrical Non-Contact Safety Switches by Allen Bradley Guardmaster. These switches ensure a superior level of security and protection to reduce risk of injury, damage to equipment, and overall downtime.
The Sensaguard safety switches feature advanced latest generation Radio Frequency Identification technology for coding and inductive technology for sensing, which makes them highly reliable and tamper-resistant. These switches are designed to be installed on machine guard doors, offer tolerance to door misalignment, and have a large sensing range. These versatile switches can meet a broad range of industrial applications.
These safety interlock switches can be connected standard safety relays, SmartGuards and safety I/O blocks to suit your needs. They also maintain PLe, SIL 3, Cat 4 rating even with multiple units connected in series. They have a high IP69K rating, which ensures that they can withstand powerful jets of water and are fully protected against dust ingress. The Sensaguard switches are a cost-effective solution and are perfectly suited for use with sliding, hinged, and lift-off machine guard doors.
Features and Benefits:
• 3 x PNP outputs (including 1 auxiliary)
• Excellent IP69K environmental protection rating
• Highly tamper-proof due to secure RFID sensing
• No dedicated controller is required
• LED indication for door status and fast troubleshooting
• Can be connected in series with other safety components (light curtain, E-stops, key interlock switches)
• Superior reliability due to short-circuit and over-voltage protection
• Uses the standard proximity brackets
• Multiple sensing directions offers greater flexibility
• Excellent IP69K environmental protection rating

Note: Supplied with actuator. Stainless steel version is suitable for use in harsh environments.
Standards: IEC60947-5-3, IEC 61508, EN954
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.
