SICK TR4 Safety Switch, RFID Actuator Included, Valox

This safety switch is a non-contact RFID interlock designed for safeguarding access points in industrial automation. It provides two monitored semiconductor safety outputs suitable for series connection within a control cabinet and operates from a 24V DC supply. The device is built for continuous industrial use with LED status indication and a 3M PVC cable for straightforward wiring.

• SIL3 safety integrity enabling high-risk application use
• PL e category 4 delivering Advanced fault tolerance
• 200mA output current supporting low-power safety devices
• IP69K protection allowing high-pressure washdown capability
• -25 to 70°C rating preserving operation across temperature ranges

• Suitable for food-processing machinery with washdown regimes
• Ideal for automated assembly line guard monitoring
• Used for safety fencing where Compact interlocks are required
• Can be used for robotics cell door monitoring with diagnostics
• Suitable for control-cabinet series connection with diagnostics

It provides two self-monitoring semiconductor outputs (OSSDs) with automatic fault detection.

The system uses an included RFID actuator that pairs to the uniquely coded sensor surfaces for non-contact switching.

The device has a 3M PVC-sheathed cable, 6.5mm diameter, 0.25mm² conductors and supports extension up to 200m.

Upon a fault at least one safety-related semiconductor output switches to the OFF state to maintain a safe condition.

The device uses a TM of 20 years for performance assessments in accordance with applicable standards.
