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

Allen Bradley Guardmaster Non-Contact Safety Switch, Unique Coding, 18mm Operating Distance - 440N-Z21US2HN9
Engage your protective measures before your equipment starts with this non-contact safety switch from Rockwell Automation's Allen Bradley Guardmaster series. The actuator's unique coding means it only works with its partner sensor to protect your system against tampering. It uses RFID technology to tolerate up to 23mm of misalignment, giving you reliable safety device activation. As indicated by its IP69K rating, this unit is dust-tight and fully protected against powerful hot water jets to perform in demanding environments where steam-cleaning happens regularly.
• Low current consumption of 50mA for energy-efficient switching
• Durable PBT-GF body provides high impact resistance for longevity
• Front-facing LED indicators signal machine status for clear diagnostics
• Slim unit depth of 20.65mm for mounting in low-profile spaces

How do I set up this non-contact safety switch?
This safety switch's sensor comes unprogrammed, meaning you need to teach it your actuator's coding before you can use it. Simply power on your sensor and actuator and leave them in sensing distance for at least two minutes until the sensor has automatically learned the correct coding.
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.
