General Purpose Incremental Encoders
Deliver precise digital feedback for fractional horsepower motors
in relatively clean environments. Incremental encoders with integral
shaft size ranging from 1/8" to ˝" and housing size ranging from 1
to 2.5 diameter include electrical interface via side or end mounted
MS connectors with choice of flange, servo or face mounting configuration
Motor Mount Incremental Encoders
For stepper motor or
servo motor control, motor mount encoders install easily without
adaptors or extra hardware for fast, simple direct to motor
installation (or mounting to other free shafts). Available
in commercial, industrial-duty and commutation motor versions. Choose
from ring-mount, hubshaft or hollowshaft mounting
configurations. Our motor mount incremental
reliable feedback for servo and stepper motor applications,
even high speed motors up to 12000 RPM. Ruggedized versions
with unbreakable metal disks are available for harsh environments
or heat up to 120°C. Commutation encoders apply
optional 3 phase communication tracks to replace traditional
Hall Effect sensors.

Ultra Performance Resolvers
Our brushless construction uses a rotary transformer to pass
the reference signal to the rotor. This design eliminates
the normal brushslop ring sliding contact used in conventional resolvers.
Since the brush and slip ring are life limiting components and can
be a source of noise in harsh environments, the transformer coupled
units enhance reliability and performance.
Industrial Frameless Resolvers
Our brushless resolvers are the ideal position feedback transducer
for brushless motors, robots and direct drive motors in precision
rotary platforms and similar servo applications. They are rugged,
reliable, provide absolute position information and are able to
operate at 155 degree Celcius and are impervious to most particulate
and liquid process contaminants.
The industry standard Size 11 resolver series has its own
precision bearing system, making it ideal for coupling mounting.
Its brushless construction uses a rotary transformer to
pass the reference signal to the rotor -eliminating components
that can limit life and cause noise. Series 11 has excellent
angular accuracy and repeatabilty. Alternatively,
the R11 shaft accepts pinions or pulleys for use in rack
and pinion or cable measuring systems. Series 11 resolvers
are rated up to 155C for high temperature applications.
Harowe R25 Heavy Duty resolvers are designed for reliability
in adverse operating conditions. Brushless resolvers
are the better choice over encoders for applications that
involve very high temperature, vibration and shock and dirty
environments. Unlike similar duplex-bearing packages,
the R25 uses a front-and-rear bearing arrangement that provides
two to three times the radial load bearing capacity and
up to ten tomes the L10 life of a package with duplex bearings.
Rated for ruggedness with IP65 protection, 125C continuous
duty, shock resistance to 200g and vibration resistance
Provide absolute position feedback for brushless motors,
robots and direct-drive motors in precision rotary platforms
and similar servo applications. This series is ruggedized
against vibration and shock, able to operate up to 200 C,
resistant to noise, and impervious to most industrial contaminants.
Options include multiple speeds, radiation hardened, high
temperature, flux shielding technology and stainless steel
High Accuracy Frameless
The 700 Series provides maximum accuracy and minimum error
for demanding position and velocity applications such as
robotics. HaroMax resolversT sizes 15 and 21 feature
a tooth-wound design that reduces electrical error 50 percent
less than that of a standard resolver. and incorporates
windings that are manufactured and installed completely
automatically. The automatic installation provides
the least amount of part-to-part variation for the greatest
consistency. Able to operate up to 200 C with
high shock and vibration resistance.
