Faulhaber expands its portfolio with
the high-precision IER3 and IERS3
encoders. Both encoders are highly
precise and have an excellent signal
quality, thanks to the optical measuring
principle. A DC-micro-motor or
brushless servo can be positioned
with an accuracy of 0.1 to 0.3° with the
IER3 and IERS3. Encoders are
therefore the ideal solution for
high-precision positioning applications.
These encoders form a singlechip
opto-reflective system, as the
LED, photo-detectors, the analysis
unit and interpolation levels are
installed in one chip. Both encoders
are available with Line Driver, which
generates complementary output
signals and makes the transmission of
data particularly resistant to electrical
interference. The IER3 provides the
highest resolution for its class (up to
10,000 lines per revolution). The
encoder achieves an angular resolution
of 0.009° with the evaluation of
40,000 edges per revolution. The high
resolution results in high control
dynamics and precise speed control.

The couplings experts at Reich-Kupplungen
have designed the new highly
flexible TOK couplings specifically to
meet the high requirements of engine
manufacturers and test bench
operators. The design of the TOK
series manages the critical resonance
frequencies of the drive train to below
the operating speed range. By
employing torsional vibration
calculations and dampening the
alternating torques generated by the
engine’s combustion process, all the
drive components are protected
against critical shocks and loads, thus
increasing the service life and
availability of the entire installation.
Designed for speeds of up to 10,000
rpm, they offer a high torsional
flexibility and torque transmission
capacity from 100 up to 70,000 Nm
and are particularly well suited in test
benches for combustion engine
testing. Their design also permits them
to be used on flexibly mounted
engines in various drive trains. It
comprises coupling sizes for a torque
range from 1 600 to 140,000 Nm.

Today, the requirements for seals are
getting more and more complex.
Companies now require seals to be
temperature, vapour, pressure and
chemical resistant. For such applications,
the company, COG has developed
a new range of high quality
‘FFKM’ material ‘COG Resist’. The
company launches 4 new compounds:
2 universal materials, 1 special FFKM
compound for use in the oil & gas
industry and 1 for the food & pharmaceutical
industry. The 2 universal
materials, COG Resist RS 75 AL and RS
80 AL demonstrate outstanding
resistance to chemicals, acids and a
low gas permeability. RS 75 AL is heat
resistant up to temperatures of 325 °C,
and RS 80 AL up to +260°C. The COG
Resist RS 92 AED seal material was
developed for applications where
resistance to explosive decompression,
high pressure, extraordinary
chemical and thermal resistance is
required like the oil and gas sector.
COG Resist RS 75 HS developed for
the highest demands of the food and
pharmaceutical industries.
