EOL Sealed Housing Option - PCN 1021 4/11/2013 This PCN is a formal notification that US Digital is discontinuing the Sealed Housing option for the following products:
  • A2 Absolute Optical Encoder
  • A2T Absolute Optical Inclinometer
  • H1 Ball Bearing Optical Shaft Encoder
  • H3 Ball Bearing Optical Shaft Encoder
  • S1 Optical Shaft Encoder
  • S2 Optical Kit Encoder
The Sealed Housing option provides the encoder with low level capability of surviving in moisture environments, however the encoder is NOT water proof or intended to be used in applications where this is required.		 Download

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 10 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.
