Incremental rotary encoder S1

opticaldigitalLine Driver

Ball-bearing option tracks 2-channel quadrature, TTL squarewave outputs 3rd channel index option available on some resolutions Wide operating temperature Product Description 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 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. Connection to the S1 series encoder is made through a 5-pin standard connector. The mating connectors are available from US Digital with several cable options and lengths.
