Overview
The Sick ZLM1-C1121S03S10 (part 1042781) is a professional-grade ZoneControl photoelectric sensor designed for zone-based detection and control in industrial conveyors, packaging machinery, and material handling systems. This integrated logic module combines photoelectric sensing with pneumatic valve actuation, eliminating the need for separate control electronics and simplifying system design for accumulation and zone control applications.
Key Features
- Built-in pneumatic solenoid valve output—eliminates external control logic
- 24VDC supply with 1W coil rating; 60mA switching output
- 200Hz switching frequency for responsive, real-time zone detection
- PNP switching output for flexible integration with sensors and controls
- M12 male connector with 4-pin M8 receptacle cable (1.2m standard length)
- Side-frame mounting for compact installation on conveyor frames
- IP40 enclosure rating suitable for standard industrial environments
- Operating temperature range: –10°C to +55°C
