S6 Product Description
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 default torque version has a sleeve bushing designed to provide torque and feel ideal for front panel human interface applications.
- The ball-bearing version uses miniature precision ball bearings that are suitable for high-speed and ultra-low torque applications.
- The light static drag option has a sleeve bushing that does not intentionally add torque for low RPM applications where a small amount of torque is acceptable.
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.
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 150Ω resistor in series with a .0047 μF capacitor placed across each differential pair. The capacitor conserves power; otherwise, power consumption would increase by approximately 20mA per pair or 60mA for three pairs.

Based on our continuous process improvement program, US Digital is changing the current marking method for our EM1 and EM2 encoder modules to a serialization method. This change will allow for each module to have a unique code; the current marking method is based on a date code system that includes all encoder modules produced within a specific week / year. The serialization system will be based on a hexadecimal system. |
