German Schneider Telemecanique encoder, Schneider Telemecanique models, Schneider Telemecanique price

Schneider Telemecanique encoders are used to measure physical quantities such as speed, position, velocity, or angle bai. They are sensors that convert mechanical displacement du into electrical signals zhi, and are classified into incremental and absolute types. Incremental encoders generate pulse signals, and the number of pulses can be used to measure speed, length, or position. For absolute encoders, each position corresponds to a digital value of displacement. Inside the encoder, there is a rotating disk (code disk) with several transparent and opaque windows. A photoelectric receiver collects intermittent light beams, thereby converting light pulses into electrical pulses, which are then processed and output by electronic output circuits.

Schneider Telemecanique encoder installation and usage

Mechanical installation of absolute rotary encoders includes high-speed end mounting, low-speed end mounting, and auxiliary mechanical device mounting. High-speed end mounting: Installed on the drive motor shaft end (or via gear connection). The advantage of this method is high resolution. Since multi-turn encoders have 4096 turns, and the motor rotation falls within this range, the full range can be utilized to improve resolution. The disadvantage is gear backlash error during reciprocating motion after passing through reduction gears. It is generally used for unidirectional high-precision control positioning, such as roll gap control in steel rolling. Additionally, when the encoder is directly mounted on the high-speed end, motor vibration must be minimal; otherwise, the encoder is prone to damage. Low-speed end mounting: Installed after the reduction gear, such as on the shaft end of a hoist wire rope drum or the last stage of the reduction gear shaft. This method eliminates gear backlash, provides more direct measurement, and offers higher accuracy. It is generally used for long-distance positioning measurements, such as in various lifting equipment and feed cart positioning. Auxiliary mechanical installation: Common methods include rack and pinion, chain and belt, friction wheels, and rope winding mechanisms.
