HB6M Product Description
The HB6M is a high-resolution hollow bore (hollow shaft/thru-bore) optical encoder with a machined aluminum enclosure and an anodized protective finish. The HB6M optical incremental encoder is designed to easily mount to an existing shaft to provide digital feedback information. Typical applications include motor feedback, process control, robotics, textile machines, and elevator controls.
The HB6M bearing style encoder features a hollow bore that accepts shaft diameters from 0.236 in. to 0.750 in. in diameter. The encoder slips over the shaft and is locked into place with two 6-32 set screws. A flexible anti-rotation mount makes the encoder more tolerant of shaft runout than a standard kit encoder. The HB6M can accommodate shaft runout up to 0.030 in. axial and 0.010 in. radial. The flexible tether provides single-point mounting for bolt circle diameters from 2.5 in. to 5.0 in.
The HB6M housing comes standard with a closed cover or an optional hole in the body to allow a shaft to pass completely through the encoder.
A secure connection to the HB6M Series encoder is made through a 5-pin (single-ended versions) or 10-pin (differential, high-voltage or open-collector versions) latching connector. The mating connectors are available from US Digital with several cable options and lengths.

| HB5M, HB6M & HD25 - PCN 7315 |
5/17/2023 |
As part of our ongoing continuous improvement efforts, we are updating our HB5M, HB6M and HD25 series of optical encoders to make product labeling clearer and permanent. The aluminum housing of these encoders will now be anodized black, and labeling will be laser etched onto the surface, providing more contrast and legibility. Previously pin-outs were machined into the housing and product labeling was printed onto an adhesive label that was placed on the side of the product. Product labeling will also now appear on the top surface of the encoder near the pin-out labeling. |

| 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. |

| 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. |
