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 . Three shaft torque versions are available. The standard torque version has a sleeve bushing designed to provide torque and feel 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. The internal differential line driver (26C31) can source and sink 20mA at TTL levels for differential versions. The recommended receiver is the industry-standard 26C32. Maximum noise immunity is achieved when the differential receiver is terminated with a 150 Ω resistor in series with a .0047 μF capacitor placed across each differential pair.
