H5 Product Description
The H5 series ball-bearing optical shaft encoder has a molded polycarbonate housing and utilizes either a 5-pin or 10-pin latching connector. This non-contacting rotary to digital converter is designed to provide digital feedback information.
The H5 is fully assembled with a brass shaft, two 1/4 in. ID by 1/2 in. OD heavy-duty ball bearings and a mounting plate. The mounting plate comes with 2 mounting holes for #4 size screws.
A secure connection to the H5 Series encoder is made through a 5-pin (single-ended versions) or 10-pin (differential or high-voltage versions) latching connector. The mating connectors are available from US Digital with several cable options and lengths.
The internal differential line driver (26C31) can source and sink 20mA at TTL levels for differential versions. The recommended receiver is the industry-standard 26C32. Maximum noise immunity is achieved when the differential receiver is terminated with a 150 Ω resistor in series with a .0047 μF capacitor placed across each differential pair. The capacitor conserves power; otherwise, power consumption would increase by approximately 20mA per pair or 60mA for 3 pairs.

| EM1 & EM2 Update - PCN 4199 |
1/14/2014 |
Based on our continuous process improvement program, US Digital is changing the current marking method for our EM1 and EM2 encoder modules to a serialization method. This change will allow for each module to have a unique code; the current marking method is based on a date code system that includes all encoder modules produced within a specific week / year. The serialization system will be based on a hexadecimal system. |
