PCA - Plant Control and Automation offers a wide range of locally assembled encoders and other switching devices, including the AWD-5000 linear to rotary converter, designed to provide a means of converting linear travel into rotary motion.
To achieve this conversion the AWD-5000 features a spring loaded 200mm circumference drum, which holds the retracting wire. When the assembly is fitted with a 200PPR encoder, the output from the encoder is a direct reading of 1mm per pulse. The maximum measuring length is 5m.
To complete the measuring system, one of three different types of rotary encoders must be attached, as the picture shows. For incremental output users should select from the INSG series, for absolute multi-turn parallel output the MzSF series should be used, and for serial data output absolute multi-turn encoders the NzSF series is ideal.
