IR Photoelectric Encoder Sensor 4Pin

<p>This speed measuring sensor is a wide voltage, high resolution, short response time, and the switch output speed measurement module. It can test the motor’s rotational speed with a black encoder (measured spec. is related to the encoder, the inner diameter of D type encoder that provided is 4mm, can be used for motor output shaft w/ 4mm diameter, which is TT motor we matched, yellow shell and white axis)</p> <hr /> <h4>Features and Specification:</h4> <ol> <li>Signal output: A, B two way; The TTL level</li> <li>Disc diameter: 24mm</li> <li>Inner Disc Diameter:: 4 mm</li> <li>The encoder resolution is about 20 line</li> <li>Speed measuring sensor configuration: The configuration can measure 1 road motor speed</li> </ol> <hr /> <h4><strong>Package Includes :</strong></h4> <p>1 x Double Speed Measuring Module kit</p> <p>1 x Screw set</p>
