US Digital E5 Motor Encoder Description

Restriction of Hazardous Substances

The US Digital E5 motor encoder mounts directly to a motor or other rotating shaft. This optical encoder features a rugged, glass-filled polymer housing and is designed for easy installation and removal.

The E5 encoder contains a precision machined aluminum hub with a specially patterned Mylar disk. This disk, in combination with our proprietary optical encoder module, creates a system that is highly tolerant to mechanical misalignment. 

The E5 is a versatile motor encoder, with four base configurations and three cover styles which allows it to fit a wide range of applications. This optical rotary encoder also has four available outputs—single-ended, single-ended High-Voltage, differential, and Avago differential. This incremental encoder is designed for use with a secure latching connector—connector/cable sold separately.

BROADCOM/AVAGO REPLACEMENTS:

US Digital's E5 encoder may be used as a replacement for Avago HEDL-5500, HEDL-5600.

Product Change Notifications

Title Date Description Download
E2, E5 Packaging - PCN 7190 8/31/2021 As part of our ongoing continuous improvement efforts, US Digital is implementing a change to the individual packaging options of our E2 and E5 kit encoders. It is important to note that this change will not affect the bulk packaging option, also known as our “B” packaging option. Download
Update to 1" and 2" Disks - PCN 6232 5/24/2018 This notice is to inform our customers of a minor disk design modification that is being implemented for standard 1" and 2" disks. This is a continuation of a change that was implemented for our index disks in 2015.

We are revising the text on the disk, adding the US Digital logo and a line that is used internally by our manufacturing group.

The change does not effect the quadrature or index tracks; therefore, it has no impact on form, fit, or function.		 Download
HUBDISK-1 Packaging Change Notification - PCN 6297 4/30/2018 As part of our ongoing continuous improvement efforts, US Digital is implementing a change to the packaging of our 1-inch Hubdisk assemblies.

We are replacing the current plastic tube packaging with a 25-count plastic tray. The tray is a two-piece design with a snap-on lid and anti-static coated for ESD-sensitive environments. This change is designed to enhance the ease of handling for our customers, easy removal of the individual hubdisk, and protection against potential damage due to long-term storage of hubdisk assemblies.

This change does not affect form, fit, or function of the final product.		 Download
Hub Set Screw Production Change - PCN 5367 7/20/2015 As part of our ongoing continuous improvement efforts, US Digital is implementing a change related to the production of our 5/16" (.313), 8mm (.315), 3/8" (.375), and 10mm (.394) HUBDISK assemblies. We are adding a low-strength threadlocker to the set screw during our assembly process to assist in securing the set screw in the hub during transportation. This will aid in the set screw retention of these specific hub sizes; ensuring the retention is sufficient and avoid the potential of them backing out of the hub assembly during transit. This change does not affect form, fit, or function. Download
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. Download
EM1 LED Die - PCN 1016 2/7/2013 As part of US Digital’s continual assurance of supply strategy, we have qualified additional sources for our LED die used in our EM1 encoder module, which in turn impacts all of the following products:

EM1, E2, E3, E5, E6, H1, H15, H3, H5, H6, HB5M, HB6M, HD25, PE, S1, S2, S5, S6, T5 and T6

The device specification will remain the same, i.e. there will be no change to form, fit, or function of the product(s) as specified by US Digital. The appropriate quality and reliability testing have been performed on representative products to ensure normal parametric distribution, consistent with US Digital's quality and reliability standards.		 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 similarly 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 of 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
