SICK TR4 Safety Interlock Switch, RFID Actuator Included, Valox

This safety interlock switch is a non-contact RFID device designed to monitor access points in industrial machinery and guarded areas. It provides two safety outputs with self-monitoring semiconductor technology and is intended for integration with safety evaluation units. The unit operates from a 24V DC supply and includes an actuator, offering multi-directional actuation for demanding production environments.

• SIL 3 safety level increases functional safety assurance
• PL e Category 4 achieves high performance in control systeMS
• IP67 IP69K protection ensures dustproof, waterproof operation
• Self-monitoring outputs limit dangerous output current to 200mA
• 360 MS release time supports controlled safety restart behaviour

• Suitable for safeguarded machinery access monitoring
• Ideal for conveyors requiring non-contact interlock switching
• Used with safety controllers in series connection architectures
• Can be used for hygienic washdown environments requiring IP69K
• Used for installations needing multi-directional actuation flexibility

It runs from 20.4V DC to 26.4V DC and consumes ≤50mA typical.

Two self-monitoring semiconductor outputs (OSSDs) provide safety signals with internal diagnostics.

It operates between -25°C and +70°C for standard industrial conditions.

It uses an M12 8-pin connection with a 0.2m cable and supports long cable runs up to 200m.

It withstands 10Hz to 55Hz vibration at 3.5mm and shock up to 30g for 11 ms.
