German Telestar encoder Telestar model Telestar price

Telestar encoders are used to measure speed, position, speed, angle, and other bai physical quantities. It is a sensor that converts mechanical disduplacement into eleczhitrical signals, and is divided into incremental and absolute types. Incremental encoders generate pulse signals, and the pulse count can be used to measure speed, length, or position. For absolute encoders, Each position corresponds to a digital value for displacement. Inside the encoder, there is a rotating disk (code disk), with several transparent and opaque windows, using photoelectric receivers to collect intermittent light beams, thus, converting light pulses into electrical pulses, which are then processed and output by electronic output circuits.

Telestar encoder principle

An optical encoder uses the principle of grating diffraction to achieve displacement-to-digital conversion, through photoelectric conversion, converting the mechanical geometric displacement on the output shaft into pulse digital quantities as a sensor. A common optical encoder consists of a code disk, a light-emitting element, and a photosensitive element. The code disk is essentially a disk engraved with regular transparent and opaque lines. The luminous flux received by the photosensitive element changes synchronously with the transparent lines. After shaping, the waveform output from the photosensitive element becomes a pulse signal. For each revolution, a pulse is output. Based on the pulse changes, the equipment displacement can be precisely measured and controlled. Incremental encoders directly use the photoelectric conversion principle to output three sets of square wave pulses: A, B, and Z phases; The phase difference between the A and B pulse groups is 90º, allowing easy determination of the rotation direction. The Z phase outputs one pulse per revolution, used for reference point positioning. Its advantages include simple principle and construction, a mechanical average life of tens of thousands of hours or more, strong anti-interference capability, high reliability, and suitability for long-distance transmission. Its disadvantage is the inability to output absolute position information of the shaft rotation.
