SICK deTec4 Core Series Light Curtain Receiver, 30 mm Resolution

This light curtain is a safety sensing device designed for industrial environments to protect personnel and machinery by monitoring a defined protective field. It operates as a receiver within a paired optical system, providing a Compact protective height option and optical synchronisation for use where safeguarding access to hazardous areas is required. The unit accepts a 24V supply and provides semiconductor switching outputs to Interface with control and safety relays.

• 30mm beam resolution detects small object intrusion
• 10 MS response time enables Rapid shutdown of hazardous motion
• Type 4 classification fulfils highest safety category requirements
• 24V supply with PNP OSSD outputs simplifies integration
• Optical synchronisation eliminates mechanical alignment complexities

• Suitable for safeguarding machine access points on production lines
• Ideal for use with safety relays and interlock circuits
• Used for perimeter protection on automated handling systems
• Can be used for presence detection in robot cells

It uses a 5‑pin M12 plug with a 150mm cable lead and 4.3mm cable diameter.

On fault, at least one OSSD is forced OFF and cross‑circuit faults trigger a lock‑out state.

It is rated IP65/IP67 with an operating temperature range of -30°C to +55°C and specified vibration and shock resistance.

It meets SIL 3 and PL e with a PFHD of 3.7x10-9 and a mission time of 20 years.
