Double Speed Photoelectric Measuring Module

This speed measuring sensor is a wide voltage, high resolution, short response time, and the switch output speed measurement module. It can test the motors 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) Features and Specification: Signal output: A, B two way; The TTL level Disc diameter: 24mm Inner Disc Diameter:: 4 mm The encoder resolution is about 20 line Speed measuring sensor configuration: The configuration can measure 1 road motor speed Package Includes : 1 x Double Speed Measuring Module kit 1 x Screw set Specifications :-
