SICK WL100-2P3439 Miniature Reflective Photoelectric Sensor IP67 100mA

SICK WL100-2P3439 Miniature Reflective Photoelectric Sensor IP67 100mA

I. Product Positioning
The WL100-2P3439 is a miniature reflective photoelectric sensor from SICK's W100-2 series, designed for space-constrained industrial applications requiring high-speed, reliable detection. Its 11 mm × 31 mm × 20 mm ABS/PC/POM plastic housing ensures IP67 protection while remaining extremely compact, making it ideal for installation in tight spaces such as robotics, electronics manufacturing, and logistics equipment.

II. Core Features and Advantages
1. Detection Principle
• A retro-reflective dual-lens system with a polarizing filter enables stable detection of highly reflective or transparent objects.
• A built-in visible red LED (632 nm) with a beam spot diameter of Ø 280 mm (at 4 m) allows for easy visual alignment and adjustment.

2. Detection Range
• Using the standard P250 reflector: 0.01 m to 5.5 m
• Maximum range: 0.01 m to 7.2 m (using the PL80A reflector)

3. High-Speed ​​Response
• Response time ≤ 0.5 ms
• 1 kHz switching frequency, meeting real-time counting and presence detection requirements for high-speed conveyor lines and placement machines.

4. Output and Interface
• PNP switching output, 100 mA load capacity
• One-touch light/dark on switching reduces PLC programming workload
• M8 3-pin metal connector, plug-and-play, easy maintenance

5. Stable and Reliable
• Wide-range power supply range from 10 V DC to 30 V DC, ±10% ripple tolerance
• Multiple protections for reverse polarity, short circuit, and overcurrent
• MTTFD (954 years), industry-leading mean time between failures

III. Typical Applications
• Electronics and semiconductors: PCB in-and-out board inspection
• Packaging machinery: Monitoring the presence of transparent film or glass bottles
• Automated warehousing: Pallet confirmation on shuttles and conveyor lines
• Robotic grippers: Part presence detection within micro-grippers
