MOTOR SPEED SENSOR / MOTOR ENCODER (5mm)

Application:

• Widely used in motor speed detection, pulse count, the position limit, etc. 

Features:

• Using imported groove optical coupling sensor, width 5mm.
  
• It have the output state light, if output is high level, the lights are off. If output low level, its 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 approx.
• Use the LM393 wide voltage comparator.

Wiring specification:

• VCC Connect the positive 3.3 or 5 V power supply
  
• GND Connect power negative
• DO TTL switch signal output
• AO This module does not work
