The wenglor OY2P303A0135 is a high-performance Time-of-Flight (ToF) laser distance sensor designed for robust industrial use. It measures distances up to 3000 mm, with a configurable detection range from 200 to 3000 mm and a switching hysteresis under 15 mm.

The sensor uses a 660 nm red laser and operates under Laser Class 1 (eye-safe). 

Its beam divergence is very low (< 2 mrad), with a spot diameter growing from about 5 mm at close range to ~9 mm at 3 m. 

Electrically, it runs on 10–30 V DC, consumes less than 50 mA (at 24 V), and supports switching frequency up to 1000 Hz, with fast response time of 0.5 ms — making it suitable for dynamic measurement and fast-moving production environments. 

Two switching outputs (PNP, NO/NC configurable) are provided, with a switching current up to 200 mA. The sensor includes built-in protections: short-circuit, reverse-polarity and overload protection. 

Mechanically, the sensor housing is made of plastic (ABS / PC) with a PMMA optical cover; it’s lightweight (~37 g) and rated IP68 for dust and water resistance. Connection is via standard M12 × 1 (5-pin). Adjustment is via a simple teach-in procedure. 

One of the distinguishing features is wenglor’s interference-free “wintec” technology — enabling reliable detection even of black, shiny, or inclined objects, and allowing multiple sensors to be mounted close together without mutual interference; performance remains stable even under strong ambient light (up to 10,000 Lux)

Thanks to these features, OY2P303A0135 is often used for applications like stack-height measurement (wood, tiles, panels), conveyor/tray monitoring (even with reflective or dark surfaces), presence detection in packaging or logistics, and clearance / collision checks in automation — tasks that demand robust, high-speed, and material-independent distance sensing.
