SICK STR1 Safety Switch, RFID Actuator Included, Vistal

This non‑contact RFID safety switch provides monitored access protection for machinery in industrial settings. Designed for use where a safety interlock is required without mechanical wear, it operates from a 24V DC supply and offers self‑monitoring semiconductor outputs for integration into safety circuits. The device is housed in a Durable VISTAL® enclosure and is suitable for installations outside hazardous zones.

• SIL 3 safety integrity level provides high risk‑reduction capability
• PL e Category 4 delivers compliance with demanding safety standards
• Two safe OSSD outputs enable direct connection to safety relays
• Auxiliary contact complements OSSDs for enhanced diagnostics
• 10m cable length supports remote mounting without junctions

• Suitable for monitored guard doors on production lines
• Ideal for integration into safety relay‑controlled systems
• Used with control cabinets for series‑connected safety chains
• Can be used for wash‑down environments requiring high ingress protection
• Used for access control where actuator coding prevents tampering

The enclosure meets IP67 and IP69K to withstand dust, high‑pressure and high‑temperature wash‑down.

In a fault at least one safety‑related semiconductor output is driven to OFF to maintain a safe state.

The unit operates between -30°C and +70°C for applicable serial number ranges

It uses a seven‑core PVC cable, 10m standard length, with conductor cross‑section 0.12mm² and cable diameter Ø5.5mm.

The sensor is RFID‑based with a uniquely coded actuator supplied, providing a high coding level to reduce manipulation.
