Technical content

Part No.: LTOE-15DB1 DATA SHEET Page: 1 of 8 BNC-OD-C131/A4 1. Description This is a transmissive optical encoder sensor for closed-loop position detection system. It consists of a collimated Red LED and a multiple sets of photo detectors OEIC enclosed in a C-shape plastic housing. The photo detectors IC is designed by CMOS process which with the features of low consumption current and wide operating voltage. The collimated light source consists of a 650nm AlInGaP LED and a collimated lens. By the design of this highly collimated light source to cooperate with the photo detectors IC, this optical encoder is extremely tolerant to mounting misalignment.
