The 62S22-L4-120S encoder is a common digital encoder used in many industrial applications. It is a two-channel optical quadrature incremental encoder with an integrated light source. This encoder has an absolute accuracy of +/-0.5 arc-seconds over an angular range of 360 degrees. With a ruggedized micro-controller and robust tachometer digital output it is able to provide extremely accurate and reliable speed measurement.

The 62S22-L4-120S encoder is typically used in applications that need a basic angular position measurement or rotational speed measurement. It is used in industrial situation such as the control of motors, medical devices, laboratory measurement systems, amusement parks and even automotive applications.

This encoder can detect the angular direction and direction of rotation of an encoder shaft. The principle of operation involves a light source (LED) and a sensor which combine to form an opto-coupler. When the encoder moves, the light emitted by the LED passes through the code wheel which is mounted onto the encoder shaft. This code wheel comprises of alternating light/dark rows of a unique pattern. The sensor then receives the light signal and sends a pulse wavetrain (A and B channel) to the controller which is then used to determine the direction and speed of rotation.

The encoder consists of a compact size module with all the necessary components such as the LED, the code disk, the opto-coupler and the micro-controller all integrated into one unit for easy installation and handling. It also has a LED driver/interface circuit which allows the LED current to be adjusted to provide consistent output from the opto-coupler even when the LED current fluctuates due to temperature changes.

The 62S22-L4-120S encoder is a robust, reliable encoder which is ideal for a wide range of applications. It is capable of providing highly accurate measurement of angular position and speed even under harsh environmental conditions. The integrated light source and LED driver/interface make it a convenient and cost-effective alternative to separate encoders and tachometers.
