The RPM-075PTT86 with Phototransistors PHOTO LINK MODULE is a small, compatible and reliable optoelectronic device manufactured by ROHM. It consists of a high-quality photo-transistor opto-isolator array, which is a simple and low-cost solution to transmit digital signal in the industrial automation system. It is adopted for high-speed sequential light beam applications such as barcode scanning and paper-sheet revolution sensing. The module reduces interface noise, current consumption, power consumption and system cost. It is available in source or sink type configurations, includes up to eight photo-transistor channels, three emitters and optional infrared filters to block out ambient light interference. The device is RoHS compliant, easy to install and maintain and comes with 4-pin M4 mounting holes.
