SICK TR4 Safety Interlock Switch, Non-Contact Actuator Included, Fibreglass Polyester, Electronic

SICK TR4 Series Safety Interlock Switch, 24V DC Supply Voltage, IP69K - TR4-SEM02CB

This safety interlock switch is a non-contact device designed to monitor access points and protect personnel in industrial automation environments. It uses RFID sensing to detect actuator presence and provides two safe outputs for integration into safety systems. The unit operates from a 24V DC supply and includes a pre-fitted actuator, making it suitable for immediate installation where space is limited and high ingress protection is required.

Features and Benefits:

• SIL3 safety integrity delivers high functional safety performance
  Category 4 classification enables highest safety category compliance
  2 safe outputs provide dual-channel monitoring capability
  Response time 45 MS minimises hazard reaction delay
  PVC cable with M12 plug supports long cable runs

Applications

• Suitable for guarding on automated production lines
  Used with safety controllers in Flexi Loop systems
  Ideal for environments requiring wash-down protection
  Can be used for access control on packaging machinery

What environmental protection does it offer?

The enclosure meets both IP67 and IP69K ratings for dust, water ingress and high-pressure washdowns.

How does the wiring Interface connect to a safety controller?

It uses a 5-pin M12 plug and supports single-sensor connection or series connection via Flexi Loop nodes.

What are the operating temperature limits for use?

The device functions between -25°C and +70°C.

How is actuator alignment handled for reliable switching?

RFID sensing with a specified assured switch-on distance of 15mm and switch-off distance of 25mm governs actuation.
