Photoelectric Retro-Reflective Sensor – WL14-2P431

The WL14-2P431 is a compact yet highly reliable photoelectric retro-reflective sensor designed for a wide range of industrial automation applications. Featuring dual-lens technology and a focused PinPoint red LED, this sensor delivers precise object detection over distances up to 17 meters, even in challenging lighting conditions.

Equipped with a single teach-in button for fast and easy setup, it supports light/dark switching and complementary PNP output, making it versatile for various control systems. The integrated polarisation filter enhances performance when detecting shiny or reflective surfaces.

Built with a rugged IP67-rated ABS housing and PMMA optics, the WL14-2P431 is well-suited for environments where space is limited but high performance is non-negotiable.
