Laser Sensors
Description
Laser through-beam sensors boast superior accuracy, ability to detect very small objects, and long 50-m operating distance. Sensitivity is adjustable via potentiometer. Sharply concentrated red laser beam (660 nm) simplifies alignment, as the light spot is visible at long distances, even in ambient light. Versions are available either with changeover outputs or with excess light output (light-ON). Contrinex, Inc., Old Saybrook, CT
