Rotational Speed sensor based on optical transmission circular grating CYRSS102OG

The rotational speed sensor CYRSS102OG is a light transmission sensor that consists of an optically transmitted circular grating and signal processing electronics. The sensor outputs both sinusoid and square wave signals with identical frequency, from which rotational speed measurement of the target object can be realized. The sensor is sealed in resin for using in harsh environments with low installation costs. This Unit functions under power supply from 4.5VDC to 24VDC. The sinusoid and square waves are output directly through the output terminals of operational amplifiers. The sensor has advantages of reverse polarity protection and transient protection.
