Product Description

Restriction of Hazardous Substances

The H1 series ball bearing optical shaft encoder has a molded polycarbonate enclosure, which utilizes a 5-pin standard connector. This non-contacting rotary to digital converter is designed to provide digital feedback information. 

The H1 is fully assembled with a brass shaft, two 1/4" ID by 1/2" OD heavy duty ball bearings and a mounting plate. The mounting plate comes with 2 mounting holes for screws #4 or smaller.

The H1 is normally designed for applications of 6 feet or less. For longer cable lengths, adding a PC4 / PC5 differential line driver is recommended.

A connection to the H1 series encoder is made through a 5-pin standard connector (sold separately). The mating connectors are available from US Digital with several cable options and lengths.
