This encoder is a wide voltage, high resolution, short response speed, Digital output speed measurement module. It can measuring the motor speed when it works with the black code disk.(This kit including 2 pieces code disk with D shape hole diameter 4mm ). This encoder used a through-beam sensor. It have high resolution and output signal is a standard square wave.
Features:
4.5V - 5.5V operating voltage
TTL outputs
20mA consumption at 5V
Code disk diameter: 24mm
D shape hole diameter:4mm
100kHz maximum PWM frequency
