E5 Product Description
The E5 Series rotary encoder has a rugged glass-filled polymer enclosure with either a 5-pin or 10-pin latching connector. This optical incremental encoder is designed to easily mount to and dismount from an existing motor shaft to provide digital feedback information.
The internal components consist of a mylar disk mounted to a precision machined aluminum hub and an encoder module. The module contains a highly collimated solid state light source and monolithic phased array sensor, which together provide a system extremely tolerant to mechanical misalignments.
The single-ended output version (S-option) is typically used with cables of 10 feet or less. For longer cable lengths, the differential output version (D-option) is recommended.
Attachment of the base to a surface may be accomplished by utilizing one of several machine screw bolt circle options. Positioning of the base to the centerline of a shaft is ensured by use of a centering tool (sold separately). The cover is securely attached to the base with two 4-40 flat head screws to provide a resilient package protecting the internal components.
A secure connection to the E5 Series encoder is made through a 5-pin (single-ended versions) or 10-pin (differential versions) latching connector. The mating connectors are available from US Digital with several cable options and lengths.
Avago Replacements:
US Digital's E5 encoder may now be used as a replacement for Avago HEDL-5500, HEDL-5600.

(1) 60000 rpm is the maximum rpm due to mechanical considerations. The maximum RPM due to the module's maximum frequency response is dependent upon the module’s resolution (CPR). For resolutions of 32 to 1999 CPR the frequency response is 300 kHz, 2000 to 3999 CPR the frequency response is 360 kHz and 4000 CPR and greater the frequency response is 720 kHz.

| E5, E6 (LD5 & LD6) Line Drive Option – PCN 7030 | 9/1/2020 | As part of our ongoing continuous improvement efforts, multiple improvements are being incorporated into the LD5 and LD6 encoder line driver boards which are options used in the E5 and E6 kit encoders. The LD5 currently is produced using a green PCB masking, it is now being changed to black PCB masking and has new markings designed to improve readability (see below). In addition to the product modification, we are also changing the packaging for the LD5 and LD6 – both will now come in a protective plastic ESD tube that is designed to better protect individual components and prevent the potential of bent connectors. Previously both the LD5 and LD6 were put directly inside an ESD bag | 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. |

| 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 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. |

| 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 has been performed on representative products to ensure normal parametric distribution, consistent with US Digital's quality and reliability standards. |

| 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 |
