1. High-Resolution Safety Light Curtain Overview
The Schmersal ZSD6/0.LTG is a Type 4 safety light curtain engineered for precision personnel protection in high-risk machinery zones. Featuring 6mm resolution and 0.5-7m adjustable detection range, this device creates an infrared protective field with ≤20ms response time. Its IP65-rated extruded aluminum housing withstands industrial environments (-25°C to +55°C) including dust, oil mist, and mechanical vibrations. Certified to ISO 13849-1 PL e (Category 4) and IEC 62061 SIL 3, the "LTG" suffix denotes integrated muting capability for automated material handling. Dual-channel OSSD outputs and beam auto-alignment technology ensure reliable operation for applications requiring finger/hand detection per ISO 13855 standards, such as press brakes, robotic workcells, and automated assembly lines.

3. Targeted Industrial Applications
This light curtain provides critical safeguarding in:
- Press Brakes: Finger protection during bending operations per ANSI B11.3
- Robotic Assembly: Access prevention in collaborative robot workcells
- Plastic Injection Molding: Mold area protection with integrated part ejection muting
- Automotive Stamping: Point-of-operation guarding on transfer press lines
