AS37-H39B Series

39-bit Multi-turn Absolute Encoder with Battery Backup

Currently Viewing:

The AS37-H39B Series is a multi-turn absolute encoder series with 39-bit resolution (23-bit single-turn and 16-bit multi-turn). The 16-bit multi-turn encoder has a battery backup sufficient to power the revolution tracking circuitry in the event of an external power loss. The AS37-H39B Series is a housed encoder consisting of a patterned disk, a light source, and photosensitive elements that translate mechanical motion to electrical signal.
