Title Date Description 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.

EM1 & EM2 Update - PCN 41991/14/2014Based 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

Product Description

Restriction of Hazardous Substances

The HB6M is a high resolution hollow bore (hollow shaft / thru-bore) optical encoder with a machined aluminum enclosure and a clear anodized protective finish. The HB6M optical incremental encoder is designed to easily mount to an existing shaft to provide digital feedback information for any motion control application.    

Typical applications include servo motor feedback, web process control, robotics, flux vector feedback, high power motors, textile machines and elevator controls.

The HB6M bearing style encoder features a hollow bore that accepts shaft diameters of 0.250" to 0.750" in diameter. The encoder slips over the shaft and is locked into place with two 6-32 set screws. A flexible anti-rotation tether compensates for shaft run out of up to 0.030" axial and 0.010" TIR. The flexible tether provides single point mounting for bolt circles from 2.50" up to 5.00".

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.

The mating connector is polarized and latches into the encoder. Depressing the latch tab allows the connector to be unplugged. Mating connector assemblies are available from US Digital stock. Custom cables are also readily available (see the Cables page). 

The differential version has an internal differential line driver (26C31) that can source and sink 20mA at TTL levels. The cable that connects to this encoder should have 3 twisted pairs for the data channels plus power and ground. Group each pair of differential signals. The recommended receiver is industry standard 26C32.

Product Notes
  • Cables and connectors are not included and must be ordered separately.
  • US Digital warrants its products against defects in materials and workmanship for two years. See complete warranty for details.
