Motor Speed Encoder Sensor Module

From the shop's description

Motor Speed Encoder Sensor Module Widely used in motor speed detection, pulse count, the position limit, etc. Feature: Using imported optical coupling sensor, width 5mm. It have the output state light, if output high level, the lights are off. if output low level ,it on. If it covered, it will output high level; otherwise it output low level. Good signal and waveform, with strong driving ability for more than 15mA. The working voltage of 3.3V to 5V. Output: digital switch output (0 and 1). Equipped with a fixed bolt hole, easily install. Small board PCB size: 3.2 cm x 1.4 cm. Use the LM393 wide voltage comparer Pin Configurations: VCC Connect the positive 3.3 5 V power supply GND Connect power negative DO TTL switch signal output AO This module does not work Package included: 1 x Speed Measuring Sensor Module Datasheet: IR Speed Module Datasheet Related Products: SENSORS | MODULES
