US Digital S5 Rotary Shaft Encoder Description

Restriction of Hazardous Substances

The S5 rotary shaft encoder converts shaft position or speed into a quadrature output signal. This rotary encoder delivers up to 20,000 PPR resolution in a glass-filled polymer housing. Available in two shaft sizes: 6 mm, 1/4 in.

US Digital offers three different torque options for various uses: 

  • Default (-D): sleeve bushing with higher damping for human interface applications.
  • Ball bearing (-B): miniature precision ball bearings suitable for high-speed applications.
  • Light static drag (-N): sleeve bushing with lower damping for low-speed applications.

This optical rotary encoder features three output options: single-ended, single-ended High-Voltage, and differential. For differential versions, the internal line driver (26C31) can source and sink 20mA at TTL levels. The recommended receiver is the industry-standard 26C32.

The S5 incremental encoder is designed for use with a secure latching connector. After you make your selections in the Product Configurator, compatible cables and connectors will be displayed below and must be ordered separately.
