This article presents a theoretical and experimental study of designing a mechanoelectric optoisolator transducer with hysteresis. Our research is centred upon designing
transducers on the basis of optical sensors, as photoelectric conversions eliminate the influence of electromagnetic disturbances. Conversion of the rotation/translation motions into electric signals is performed with the help of a LED-photoresistor Polaroid optocoupler. The driver of the optocoupler’s transmitter module is an independent current source. The signal conditioning
circuit is a Schmitt trigger circuit. The device is designed to be applied in the field of automation and mechatronics.
