SICK Retroreflective Photoelectric Sensor Block Type NPN Output IP65 0.08 - 12 m WL100L-E2231

The SICK WL100L-E2231 is a compact and highly reliable retroreflective photoelectric sensor, designed to deliver accurate detection of objects in industrial automation environments. With its block sensor form factor, this unit excels in tight installation spaces and is widely used where high precision, long sensing range, and robust performance are critical.

Utilizing a class 1 laser LED light source, the WL100L-E2231 offers a detection range from 0.08 meters up to 12 meters, enabling reliable sensing of small objects, even in high-speed applications and over large distances. The retroreflective operating principle ensures quick response with minimal alignment effort, making it ideal for conveyor systems, automated packaging lines, and material presence detection in manufacturing automation.

The sensor provides an NPN output, compatible with a wide range of industrial control systems, and is fitted with a standard 4-pin connection for straightforward integration. Sensitivity and switching logic (light/dark switching) can be adjusted via a rotary switch, further increasing adaptability to various process requirements and materials.

An IP65 rating guarantees protection against dust and low-pressure water jets, making the WL100L-E2231 suited for demanding environments. The rugged housing is manufactured from polymethyl methacrylate and ABS, providing both chemical resistance and mechanical durability. The included reflector (P250F) enhances retroreflective detection performance, and a mounting bracket is provided for secure panel installation, helping to reduce installation time and effort.

Designed for a temperature range of -10°C to +50°C, the WL100L-E2231 operates reliably across harsh ambient conditions. The fast 250 μs response time supports use in rapid material handling and automated assembly lines.

This sensor is used in industrial automation, logistics, packaging lines, robotics, material handling, and manufacturing sectors, where precision and consistent object detection are essential.
