Product Description
The Sick WL27-3P3402S178740 is a member of the RAY26 Reflex Array family of multitask photoelectric sensors. It operates on the retroreflective (retro-reflective) principle using a light band/array to detect the leading edge of small, flat, transparent, or uneven objects regardless of position within the array. The sensor features a PinPoint LED red light source, single teach-in button with AutoAdapt functionality, and PNP switching output with complementary light/dark switching modes.
