An Encoder is a device that measure the rotary position of a shaft by converting mechanical motion into an electrical signal. Encoders are digital devices, so their integration into control systems is relatively simple and doesn’t require complex electronics or circuitry. From a performance standpoint, Encoders have a lower weight and rotational inertia than Resolvers, making them more suitable for applications with high acceleration and deceleration rates. Encoder accuracy is typically in the range of 20 arcseconds. The assembly unit incorporates a Moore Reed 18DU188 rotary encoder providing a digital output of synchro angle.This is probably part of the Mk34 AFCS used on the WG13 Lynx.
