SICK TR4 Safety Switch, RFID Actuator Included, Valox

This safety switch is a non-contact RFID interlock designed for machine-safety applications where monitored access and diagnostics are required. It provides dual safe outputs with self-monitoring semiconductor signalling for integration in control-cabinet safety circuits. The device operates from a 24V DC supply and includes a 3M cable for connection, offering LED status indication and a Compact cylindrical form suited to confined installations.

• SIL 3 safety level delivering high functional safety performance
• Category 4 classification enabling Advanced safety architectures
• Two self-monitoring outputs providing separated safety signalling
• IP69K / IP67 rating permitting wash-down and high-pressure cleaning
• Temperature resilient -25°C to 70°C supporting harsh environments

• Suitable for industrial RFID interlock switch installations on guards
• Ideal for food-industry areas requiring IP69K hygiene cleaning
• Used with control-cabinet safety logic for series monitoring
• Can be used for access monitoring on automated production lines
• Suitable for integration where a Compact safety-switch form factor is needed

External faults such as short-circuit or cross-circuit are detected within the device

Supply voltage is 24V DC with an operating range of 20.4V DC to 26.4V DC and each output can source up to 200mA.

The electrical life is rated at 10x10^6 switching cycles under specified conditions.

It ships with a 3M PVC-sheathed cable with 0.25mm² conductors and permits fixed installations up to 200m total cable length.
