• 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

Standards: EN 60947-5-3, IEC 61508, EN 954

Use this non-contact safety switch from Rockwell Automation's Allen Bradley Guardmaster series to activate protective measures for your equipment. As it uses RFID sensing, it's protected against tampering to minimise disruption to your processes. The device features unique coding so each sensor only responds to its partner. This prevents the accidental starting of machines by other switches in busy systems. Thanks to a switching distance of 18mm, this unit ensures safety measures activate quickly to keep you protected from hazardous hardware.

• IP69K rating indicates dust-proof and watertight protection even against heated high-pressure water jets, for safe industrial use
• Voltage rating of 24V DC for compatibility with common power supplies
• Durable PBT-GF housing stops burning in 10 seconds or less to support fire-safety in your workplace

• CE
• UL
• EN 954
• IEC 61508

The device uses an eight-pin M12 thread plug connector. Its quick-disconnect design means you can directly connect it to your control device, so wiring is straightforward.

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.
