The S5 series optical shaft encoder is a non-contacting rotary to digital converter. Useful for position feedback or manual interface, the encoder converts real-time shaft angle, speed, and direction into TTL-compatible quadrature outputs with or without index. It operates from a single +5VDC supply.
Three shaft torque versions are available. The standard torque version has a sleeve bushing designed to provide torque and feel that is ideal for front panel human interface applications.
The no torque added option has a sleeve bushing that does not intentionally add torque for low RPM applications where a small amount of torque is acceptable.
The ball bearing version uses miniature precision ball bearings that are suitable for high speed and ultra low torque applications.
A secure connection to the S5 series encoder is made through a 5-pin (single-ended version) or 10-pin (differential version) latching connector (sold separately). The mating connectors are available from US Digital with several cable options and lengths.
