Parametric Search : Single Turn Encoders

Avago’s single-turn encoders provide unique positional information for each shaft location. This location is independent from all other locations. In an absolute single turn encoder, there are several tracks with common centers, and single light sources. As the light passes through the slots on the moving tracks, it creates shadows at intervals. Where a shadow is detected, a low state (0) is created. When the light successfully penetrates the slot a high state (1) is created. The position of the shaft is detected by reading the pattern of 1’s and 0’s. For higher resolution single turn encoders, incremental tracks are added. These tracks enable the interpolation of signals. Avago’s single-turn encoders provide high accuracy read-out for applications which require precise positional information. In addition, these single turn encoders’ use of the SSI non-proprietary serial communication protocol means that these single turn encoders can match most applications’ output requirements. These absolute single turn encoders come in a 13-bit and 16-bit resolution package to cater to the needs of a range of applications in the factory and industrial automation industry such as robotic arms, valve controls, test and measurement equipments etc.
