Product Description

Restriction of Hazardous Substances

The H3 series ball bearing optical shaft encoder has a molded polycarbonate enclosure, which utilizes either a 5-pin locking or standard connector. This non-contacting rotary to digital converter is designed to provide digital feedback information.

The H3 is fully assembled with a shaft, two 1/4" ID by 1/2" OD heavy duty ball bearings and a mounting plate. The shaft is made of brass. This design allows for an optional rear shaft extension. The mounting plate comes with 2 mounting holes for screws #4 or smaller.

The H3 is normally designed for applications of 10 feet or less. For longer cable lengths, adding a PC4 / PC5 differential line driver is recommended.

A connection to the H3 series encoder is made through either a 5-pin locking or standard connector (sold separately). The mating connectors are available from US Digital with several cable options and lengths.
