Optical Shaft Encoder Page 1 of 5 The S6 series high resolution 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 S6 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. For differential versions, the internal differential line driver (26C31) can source and sink 20mA at TTL levels. The recommended receiver is the industry standard 26C32. Maximum noise immunity is achieved when the differential receiver is terminated with a 150 Q resistor in series with a .0047 |J F capacitor placed across each differential pair. The capacitor simply conserves power; otherwise power consumption would increase by approximately 20mA per pair, or 60mA for 3 pairs. ► Small size ► 64 to 10000 CPR (256 to 40000 PPR) ► Optional differential / line-driver output ► Positive latching connector ► 2-channel quadrature,TTL squarewave outputs ► 3rd channel index option ► Ball bearing option tracks to 10,000 RPM ► Wide operating temperature ► Single +5VDC supply Mechanical Drawing USE= 1400 NE 136th Avenue info@usdigital.com Local: 360.260.2468 DIGITAL Vancouver, Washington 98684, USA www.usdigital.com Toll-free: 800.736.0194
