SICK STR1 Safety Switch, RFID Actuator Included, Vistal

This safety switch is a non-contact RFID interlock designed for industrial machine safeguarding. It provides self-monitoring semiconductor outputs for safety circuits and integrates an auxiliary contact for complementary switching behaviour. The unit operates from a 24V DC supply and offers diagnostic connectivity options for series wiring, supporting both simple T‑connector chains and Flexi Loop with diagnostics. Its construction suits harsh environments where ingress protection and a Compact form factor are required.

• SIL3 safety integrity for high‑risk applications
• PL e Category 4 performance for safety control systems
• Assured switch‑on distance 10mm for consistent actuation
• Output current limit 100mA for downstream device protection
• Operating range -30°C to +70°C for wide temperature use

• Suitable for safeguarding access Gates on production lines
• Ideal for food‑industry wash‑down zones requiring IP69K protection
• Used with safety controllers in series‑connected installations
• Can be used for perimeter guarding on automated machinery
• Used for needing multi‑direction actuation compatibility

A Compact actuator is included and is compatible with the RFID sensor alignment.

It connects via an 8‑pin M12 plug or short cable and supports safe series wiring with T‑connectors or Flexi Loop diagnostics.

LEDs provide device status and diagnostic signalling to assist fault identification.

It uses a 24V DC supply and has contacts rated for 230V AC and 24V DC signalling.
