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 3/1/2023UV-C LEDsThe SF1-3T9B5L1 and SN3-5T9B5L1 UV-C LEDs from Silanna UV feature the TO-Can package format to protect sensitive semiconductor components within the package.
