It uses a red LED light source and a five-turn endless adjuster to fine-tune sensing distance within the 20 mm to 200 mm range. The unit includes a built-in amplifier, eliminating the need for an external control module and simplifying installation. Designed with an IP67-rated enclosure and a 2-meter pre-wired cable, it is suitable for use in industrial environments where resistance to dust and moisture is required. Key Features: Adjustable Sensing Range: Detection distance adjustable from 20 mm to 200 mm using a five-turn adjuster. Diffuse Reflective Method: Detects objects directly without requiring a separate reflector. PNP Output Configuration: Open collector PNP output rated for industrial control systems. Selectable Operation Mode: Light-ON or Dark-ON switching selectable via built-in setting. Built-In Amplifier: Integrated amplification reduces external wiring and simplifies setup. Red LED Light Source (680 nm): Provides stable and visible alignment during installation. IP67 Protection Rating: Dust-tight and protected against temporary water immersion. Wide Operating Temperature Range: Reliable operation from -25°C to +55°C. The E3Z-LS81 delivers the reliability and precision required for compact object detection and positioning tasks in industrial automation systems.
