Encoders

An encoder is a device that processes a signal, typically a digital or analog signal, to create a specific code. The output of an encoder is typically a discrete output code, such as an Alphabetical Code, Binary Code, Gray Code, or a Two-state Logic Code. Encoders are commonly used in control systems, such as feedback systems or motor control systems, to provide precise feedback regarding the position, velocity, and/or acceleration of a motor shaft, as well as other aspects of the system\'s performance.

The 62NG522-LH5-02S is an optically incremental encoder. It is suitable for capturing linear motion like position, velocity, and acceleration. It is constructed in a non-contact design with a two-channel complementing phase output. The optics consists of three light emitters and a single mask wheel with pcd’s (photo conductive diodes) corresponding to the reference marks. A single output device provides a synchronous and sequential output of two channels in the same physical direction. An output frequency up to 400 kHz is available with a maximum speed of 136,000 RPM.

Application Field

The 62NG522-LH5-02S is an ideal encoder for linear motion measurement. The device is able to output A quadrature signal in order to monitor motion profiles like acceleration, deceleration, and speed. Commonly, the 62NG522-LH5-02S is used in controlling the speed and movement of automated production machinery, such as robotics, conveyors, and other devices. It is also used in industrial motors, actuators, and other motor control applications. Additionally, the 62NG522-LH5-02S can measure speed in more alternative configurations, such as speed in gearboxes and ball screws.

Working Principle

The 62NG522-LH5-02S is a non-contact optically incremental encoder that basically works through the principle of light interruption. With its two-channel complementing phase output, an output device provides different signals as the wheel attached to the shaft passes each detector.

The encoder wheel consists of a series of reference marks that act as dividers. Each reference mark is interrupted by an optically emitter and detector pair. As the wheel passes each optically emitter and detector pair, it interrupts the light which creates a signal. Each reference mark in the wheel is assigned its own unique signal as the wheel passes. This enables the62NG522-LH5-02S to output a square-wave signal according to the rotating speed, direction, and number of interruptions of the wheel.

The 62NG522-LH5-02S is designed to count impulses, or, to put another way, increments. It counts one increment for each reference mark that passes the emitter/detector pair. This means that the count is incremented by two counts for each output cycle. This provides precise information regarding the position, velocity, and position of the motor shaft.

In conclusion, the 62NG522-LH5-02S encoder is an optically incremental encoder used to measure linear motion, such as position, velocity, and acceleration. The device is capable of outputting a quadrature signal in order to provide an accurate measure of motion profiles. It consists of three light emitters and a single mask wheel that correspond to reference marks. As the wheel passes each optically emitter and detector pair, it interrupts the light which creates a signal, and the 62NG522-LH5-02S is used to count those impulses.
