OPT series short and long range distance sensors are available with either Class 1 or Class 2 laser options. The sensors have rectangular plastic housings with M12 quick-disconnects. OPT short-range diffuse distance sensors use high-resolution CMOS line array technology, eliminating material, color and brightness-related measurement differences. Analog and switch output models are available with sensing ranges from 30 to 660mm, at up to 1,500 scans per second. OPT short-range sensors start at $319.00 . OPT long-range sensors use transit time for distance measurement. Diffuse styles have a sensing range up to 10 meters; retro-reflective styles sense up to 100 meters. Analog and switch output models are available. OPT long-range sensors start at $249.00 . With a one-year warranty, OPT distance sensors are CE, RoHS, and cULus compliant.
