The S1 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.
The S1 is designed to drive cables up to 10 feet long. For longer cable lengths, adding a PC4 / PC5 differential line driver is recommended.
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.
