Opto IR Infrared Motor Speed Sensor Module Model 123, Optical Slot
The Opto IR Motor Speed Measurement Module, Model 123, is an advanced solution designed for precise and reliable monitoring of motor rotational speed in a wide range of industrial and technical applications. Featuring a cutting-edge infrared optical sensor, this module provides accurate, non-contact speed measurement, minimizing wear and extending the lifespan of mechanical components.
Engineered for compatibility with modern control systems, the module’s OUT port connects directly to the external interrupt port of a microcontroller (MCU), enabling high-precision pulse detection. When VCC and GND are connected, the signal indicator lights up to show operational readiness. If there is no obstruction in the module’s slot, the optical sensor receives infrared rays and the OUT port outputs a high-level signal. When blocked (such as by a motor encoder disk), the infrared beam is interrupted, resulting in a low-level signal and the signal indicator turns off.
