Commonly used encoder classification and various types of encoder working principle

Absolute encoder is a kind of sensor, mainly plays the role of detecting the speed, position, angle, distance and other parameters of mechanical movement. The encoder as a signal detection method has been widely used in various industries. Absolute encoder works like this: when the absolute encoder shaft drives the grating disk rotation, the light emitted by the light-emitting element by the grating disk slit cut into intermittent light, and is received by the receiving element to produce the initial signal. This signal is processed by the subsequent circuit and outputs a pulse or code signal. Absolute encoder has the advantages of small size, light weight, more varieties, full-featured, high frequency response, high resolution capability, small torque, low energy consumption, stable performance, reliable long service life. Incremental encoder encoder is an angular displacement or linear displacement into an electrical signal device. Absolute encoder common types of incremental encoder, absolute encoder, binary encoder, these three kinds of encoder and what are the differences 1,...
