Optical Incremental Encoders

Incremental Optical Encoder, AEDS-9240 is an extension of the AEDB-9340 state-of-the-art 6-channel commutation optical encoder series. Similarly, the AEDS-9240 has also been designed to enable motor manufacturers to seamlessly develop a feedback mechanism in a closed-loop servo system for Brushless DC Motor (BLDC) designs.
However, unlike the AEDB-9340 which was designed for applications requiring high speed motor system, the AEDS-9240 is specifically designed for applications requiring low to medium resolution, such as industrial sewing machines, textile machines, elevators, as well as, low to medium resolution motor systems and housed encoder makers.
This optical encoder integrates channel-A, channel-B, and channel-I for positional feedback with channel-U, channel-V, and channel-W to emulate the Hall sensor feedback for rotor commutation. All these output signals are generated from the optical sensors where the number of pole-pairs can be changed easily by re-configuring the code wheel patt
