IR Photoelectric Encoder Sensor 4Pin

From the shop's description

IR Photoelectric Encoder Sensor 4Pin is a high-quality electronic component designed for Arduino, prototyping, and educational electronics. The speed motion sensor utilize a groove IR optocoupler to sense for object between the IR emitter and IR receiver on-board. This methodology allow the module to count the number of obstruction in a given time frame. This characteristic made it very suitable for measuring the speed of rotation. The digital output is in LOW state when the sensor is not obstructed and the LED will be light up. Digital output will be in HIGH state when the sensor is covered and the LED will be turn off. An on-board potentiometer is available to adjust the sensitivity of the senso Characteristics: IC: LM393 (dual comparator) Power supply: + 3.3V ~ +5.0 V Encoder current consumption: 1.4 mA Interface or type of encoder output signal: TTL digital Output format: digital output (0 and 1) Operating temperature: 0 ° C ~ + 70 ° C Dimensions (LxWxH): 32 x 14 x 10 mm The width of the slit groove in probe: 5 mm Diameter for speed sensor mounting holes: 3 mm speed sensor module Weight: 3 g It’s perfect for DIY makers, students, and anyone building custom electronic circuits or STEM kits.
