Request InfoOptek Technology, Industrial Sensing & ControlOptek Technology Inc.'s OPR5009 SMD Optical Comparator Array is a three-channel differential photodetector hybrid array designed for high-speed, high-resolution encoder applications. Capable of a 1-MHz frequency response, each channel's open collector output switches by comparing the current levels between a pair of photodiodes on which the input light falls. A and B channels are dimensionally referenced to the Z channel for improved critical dimension control. It features internal logarithmic amplification and tightly toleranced alignment holes.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 4/10/2023Gas and Flame DetectorThe Spyglass™ SG50-F series open-path flame detectors come with triple infrared (IR3) and UV-IR options to suit a range of applications.
