The SICK W100-2 Series Photoelectric Sensor is a line of sensors compatible with standard detection principles, with variants including proximity, through-beam, and retro-reflective sensors. Retro-reflective models include transparent object detection, energetic sensors, and sensors with background blanking. Light, dark, and light/dark switching modes are available, with optional potentiometer adjustment in certain configurations. The housing design of the W100-2 Series includes M3 threaded mounting holes, spaced one inch apart, that permit straightforward, inexpensive mounting.
