New Accessories
Two new accessories, the Uni-Bracket and
Uni-Cover, are now being offered.
Combined with an Accu-CoderTM Brand
encoder, they offer a complete assembly
solution for applications involving any
NEMA Motor C-Face with a 4.5" AK pilot
register. These new accessories can also
be used independently to solve a wide
variety of applications.

Keeping an Explosive Situation Under Control
Application Success Story
When mixing explosives, the margin for
error is understandably quite small. And
when the mixing is being done
automatically in a very remote location,
the ruggedness, precision, and reliability
of EPC encoders really pay dividends.

Why You Need EPC's Opto-ASIC
Technology
At the heart of EPC's Opto-ASIC technology is
a single chip which combines all of the
components of a typical sensor board,
including the photosensor, into a single circuit.
While this in itself may sound unimportant, the
resulting benefits over traditional sensor
boards are numerous.

With EPC's Opto-ASIC Technology:
You'll get a clean, reliable signal with greater immunity to electrical noise than traditional
analog sensors. Missed and extra counts are virtually eliminated!
Speed, reliability, and signal quality are all greatly increased!
The potential for quadrature drift from exposure to time and temperature is virtually eliminated!
Your encoder will have superior resistance to particulate contamination-related signal
distortion. If dust does get into your optics, it's not as likely to cause a problem!
Power consumption is reduced!
EPC's Opto-ASIC chip provides all of these
benefits, while reducing costs and space
requirements. The chip is just 3.5mm x 4mm
and replaces all of the standard components of
a traditional sensor board, leaving plenty of
room for enhanced features.
EPC's Opto-ASIC chip eliminates the need for many board level
components, leaving room for more features while improving
performance.
EPC's Opto-ASIC equipped Model 260, perhaps the most reliable encoder in the world, has a
reliability rate of 99.95% - that's just .05% (or 1 in every 2000 units) returned for warranty service. It
is reliability track records such as this which have allowed EPC to extend it's standard product
warranty from an impressive two years to an industry-leading three years. Ask Customer Service
about other Accu-Coder™ models which use Opto-ASIC technology.
Accu-Coder™ Brand Encoders, equipped with EPC's Opto-ASIC Technology, provide a clean
reliable signal with greater immunity to electrical noise than traditional analog sensors AccuCoder™ Brand Encoders, equipped with EPC's Opto-ASIC Technology, are more reliable. The
track record speaks for itself!
EPC's Opto-ASIC technology provides a high level of noise rejection for a cleaner and more
reliable output signal. The noise from an ungrounded motor experienced by a conventional analog
sensor (left) is virtually eliminated by EPC's Opto-ASIC sensor technology (right).

In addition to the M12 (12 mm) connector on its popular Cube
Series Accu-Coder™, EPC has expanded the new connector to
include its popular 702, 725, 758, and 225 Models of Accu-Coder™
Encoders. The M12 (12 mm) connector is the connector of choice
for many other motion control components, such as proximity
sensors, and photoelectric switches. Until now, the use of the
M12 had not been available as an encoder option. Using this new
connector may allow you to reduce stocking requirements for
cordsets and other similar components, since the M12 cordset used
for your Accu-CoderTM may also be used for many of your other
motion control components.
Every Accu-Coder™ brand encoder is manufactured to EPC's
exacting standards, and backed by EPC's exclusive 3-year standard
product warranty, to ensure years of trouble free use. For complete
details contact EPC Customer Service, PO Box 249, Sagle, Idaho
83860, 800-366-5412.

The Uni-Bracket allows for the tethering of the encoder (Models
260 & 702) to any 4.5" C-Face (5.875" BC mounting holes) and can
be employed with or without the Uni-Cover. The non-conductive
bushing provides an electrical isolation barrier, negating the
potential for Electro Static Discharge and resultant encoder bearing
damage. The bushing can also be slid in or out of the forked
bracket to allow for mounting to comparably sized IEC C-faced or
other non-NEMA dimensioned motors. Even though all EPC
encoders are designed and built to robust specifications, and utilize
all-metal parts, a protective cover is often considered a cheap
insurance policy against physical abuse. The all-metal Uni-Cover
provides this protection. Designed to allow for the fitting of most
EPC thru or hollow bore encoders, the Uni-Cover matches up with
the 5.875" bolt pattern found on the NEMA 4.5" AK C-face mounts.
It is slotted to accommodate either the Uni-Bracket or the nonconductive flex of the Models 775 and 776, along with either cable
gland or body mounted connector encoder styles.
Adaptable encoders include;
Model 260 Thru-Bore Requires Uni-Bracket for motor mounting.
The most economical solution where the motor shaft is 0.625" (05
15mm) or less.
For demanding performance Vector applications where high speed
and frequency response is required (up to 8000rpm & 300Khz
respectively).
Model 702 Blind Hollow Bore Requires Uni-Bracket for motor
mounting.
Where a body-mounted connector is desired and motor shaft
diameters do not exceed 0.625" (or 15mm).
Model 775 Does NOT require Uni-Bracket.
775 "Style A" flex option allows for direct motor mounting where
shaft diameters exceed 0.625" (up to 1.375" or 35mm).
Model 776 Does NOT require Uni-Bracket.
776 "Style A" flex option allows for direct motor mounting where
shaft diameters exceed 1.375" (up to 1.875" or 48mm).
Today, many motor manufacturers provide a "Standard Mechanical
Interface" on their Vector and Inverter Duty products, such as a
4.5" or 8.5" C-face, but not always. On occasion, the scope of your
project requires that you attempt to retrofit an encoder to an older
motor so as to interface with the new drive you have selected.
Whatever the case, with EPC's complete family of "easy, anyone
can mount" motor to encoder offerings, a technically and
commercially viable solution can usually be selected and applied.
Please also see EPC's Models 770 & 771 C-face encoders for
additional motor-to-encoder solution alternatives.

Keeping an Explosive Situation Under Control
Application Success Story
EPC’s one-millionth encoder, a 713-HD10, is being installed on a
specialized truck that mixes and delivers explosives. The company
that manufactures these trucks, Ground Force, delivers them to
mining operations all over the world. They are the major supplier of
this type of equipment for several of the world’s largest copper and
gold mines, located in Indonesia and South America.

Ground Force uses EPC encoders to measure the rotation of pump
shafts and of augers. The pumps deliver wet ingredients, while the
augers deliver the dry ingredients. Ground Force uses a
straightforward sprocket and ladder chain system to drive the
encoders from these shafts and augers. The encoders are 200
pulse-per-revolution (ppr) incremental units and their output is fed
to a scaling system that converts the pulses to the rate at which
pounds or kilos of mixed product are being delivered by the truck.
A typical truck will use up to four encoders, one for each type of
component. The scaled outputs from each encoder are, in turn, fed
to a processor that monitors the various outputs to make sure that
the final mixture is, and remains, optimal.
Ground Force ANFO/EMULSION Mix & Delivery Vehicle
This same basic system has been used by Ground Force for more
than fifteen years. It has proven to be so reliable that no
alternative design has been found that satisfies their requirements.
In fact, to quote Alex Ritter, Chief Engineer, “At this point in time,
we are not even thinking about searching for an alternative
system, or about changing the design.” This is strong testimony to
the ruggedness and reliability of EPC’s encoders, especially given
the environment in which they live in this application. Not only are
they mounted on the outside of the trucks, where they have to
withstand all types of weather conditions, (mud, dust, and rough
treatment, typical in a mine) but they must be resistant to the
caustic and corrosive elements that make up the explosive
mixture. These components will rapidly find any weaknesses in an
encoder. As further evidence of Ground Force’s loyalty, and of their
satisfaction, consider the fact that they have purchased more than
1,000 encoders from EPC since 1985, and that EPC is their only
encoder supplier.
This application very dramatically illustrates the quality, durability,
and longevity of EPC encoders. It also illustrates one of EPC’s most
important guiding principals – we are not just interested in selling
products, we are interested in forging long term business
relationships.
