Short-Range Photoelectric Laser Sensors

Bulletin 45MLD Short-range Photoelectric Laser Sensors are Class II diffuse sensors designed for the packaging, material handling and semiconductor industries. These sensors provide background suppression by triangulation, establishing a fixed focal point and suppressing anything beyond the focal point. The rotatable lens also lets you adjust the laser beam spot size at the focal point down to 0.5 mm (0.02 in.) for accurate sensing of small targets such as gap detection, chip detection and crack detection in semiconductor and packaging applications.
