Metric and inch-standard shaft options compliment a host
of US, European and Japanese mounting flange options
making the Model 15S a versatile solution for a broad
range of legacy field-replacement requirements. The small
profile Model 15S has optional commutation, up to 10,000
CPR resolution, and the ability to handle the heat of high
revving motors.

With a host of US, European and Japanese flex mount
options, and bore sizes up to 0.375” or 10 mm, the Model
15T/H is a highly versatile solution for a broad range of both
motor and non-motor-mount applications. A short 1.00”
over-all height, resolutions to 10,000 CPR, and optional
commutation makes the Model 15T is an ideal upgrade
from less reliable modular encoders.

Broadly versatile design enables application to low and
fractional HP NEMA motors with bore sizes up to 0.625” or
demanding high-performance BLDC servo when configured
with commutation tracks and 120° C temp rating. Largest
bore size (0.625” or 15 mm) in the 2.00” O.D. class, making
it a cost-effective replacement solution for many HS20 and
HS25 type installations.

Finely engineered for demanding high-speed applications
above 10,000 RPM. The only all-metal modular encoder on
the planet, featuring patented 1-2-3 gapping and centering
design for quick and confident installation. With bore sizes
up to 0.625” or 15 mm and commutation optional, the
Model 121 is a reliable, all-metal upgrade from the fragile
plastic modulars common in today’s marketplace.

Historically selected as low cost digital alternative to
tachometers on Permanent Magnet motors. Expansive
Metric and inch-standard bore options (22 mm or 0.875”)
enable application to even larger frame motors. Flex Arm
mounting kit and multiple connection options provides
universal application to most US and IEC motor designs.

EPC still actively supports this integrated encoder and
coupling mount design, originally employed by motor
manufacturers prior to the advent of today’s high-temp,
thru-bore encoders. The 755A-NEMA is still a viable
alternative for new applications where motor shaft run-out
exceeds comfortable limits of thru-bore flex mount designs.
The 755A NEMA boasts resolutions up to 30,000 CPR, and a
frequency response up to 1MHz.
