The following parts are not included with the H15 and must be ordered separately if needed.

1. Cleats & Screws Kit

Part #: CLEAT-KIT
Description: Includes 3 servo mounting cleats and 3 screws.

2. Cleat (Individual)

Part #: CLEAT-5889
Description: This servo cleat is used for the mounting of the H15 encoder using a servo type system. Mounting holes should be arrayed at 120 on a 1.90" bolt circle.

3. Screws

Part #: SCREW-440-250-PH
Description: 4-40 x 1/4" stainless steel phillips pan-head screw.

Title Date Description Download
E5 Insert Overmold - PCN 1008 8/23/2011 In an effort to enhance the robustness of our E5 encoder; the four threaded inserts pressed into the base are being replaced with similar threaded nuts that will be insert-molded into the encoder base. This change in process will retain the insert with much greater strength. Download
E5 Laser Marking - PCN 1009 8/23/2011 The primary purpose for this change is to create a more durable and longer lasting solution compared to the previous stick on label solution. The E5 encoder covers will now have the US Digital logo, part number, lot code, and pin-outs laser marked onto the top surface. Download
E5 Mold Update - PCN 1007 8/23/2011 The plastic E5 base and covers have been redesigned for improved moldability and aesthetics. Design changes are primarily alteration of surface drafts, additional or increased corner radii and additional coring out of thick regions. This update was carefully done to preserve the size and shape of the encoder. The new parts are dimensionally equivalent and will fit within the envelope of the previous parts. Only the E-option covers and the G-option bases have features with dimensional changes. Download

Product Description

Restriction of Hazardous Substances

The H15 series ball bearing optical shaft encoder has a servo mount size 15 machine aluminum flange with a molded polycarbonate housing. This non-contacting rotary to digital converter is designed for applications requiring a size 15 servo mount. The H15 utilizes either a 5-pin or 10-pin finger-latching connector depending upon the encoder output option.

The H15 is fully assembled with a shaft, two 1/4" ID by 1/2" OD heavy duty ball bearings and a servo mount adapter. The shaft is made of stainless steel. The H15 may be mounted and held in position by either attaching to the 4-40 machine screw holes in the base or by using the attached servo ring and separate servo cleats (see Accessories on the next page).

The single-ended output version is normally designed for applications of 10 feet or less. For longer cable lengths, the differential output version is recommended.

A secure connection to the H15 is made through a 5-pin (single-ended versions) or 10-pin (differential versions) finger-latching connector (sold separately). The mating connectors are available from US Digital with several cable options and lengths.

For differential versions: the internal differential line driver (26C31) can source and sink 20mA at TTL levels. The recommended receiver is industry standard 26C32. Maximum noise immunity is achieved when the differential receiver is terminated with a 110-ohm resistor in series with a .0047 microfarad capacitor placed across each differential pair. The capacitor simply conserves power; otherwise power consumption would increase by approximately 20mA per pair, or 60mA for 3 pairs.
