US Digital H6 Rotary Encoder Description
The H6 ball-bearing rotary encoder converts shaft position or speed into a quadrature output signal. This rotary encoder delivers up to 40,000 PPR resolution in a glass-filled polymer housing. The brass shaft rotates on a pair of ball bearings.
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 H6 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.
