The Timken Company (NYSE: TKR) is introducing a new M15 Modular
Magnetic Encoder that provides more reliable feedback than optical
encoders to keep motors and factory-automated equipment running
longer, even in harsh environments. Encoders are used to provide
data on the speed and positioning of rotating motor shafts and
equipment. Applications for encoders are found throughout many
industries and the M15 encoder is specifically designed to perform
in dirty environments where conventional optical encoders
frequently fail due to debris interference. Unlike optical encoders
which require precise alignment to operate, the M15 is easier to
install because it uses magnetic technology that reduces complexity
and also accommodates motor shaft tolerances. This technology
eliminates interference from machine vibrations, delivering a
longer operating life and more reliable performance. �Combining its
proven sensor technology with a comprehensive understanding of
motion control, Timken has developed the M15 modular encoder to
deliver exceptional value with a reliable integrated design that is
less complex and time consuming to install,� said Greg Vanbuskirk,
business development manager, motion sensors. �The unique use of
magnetic circuitry in a compact modular unit also makes the M15
encoder a more economical option that is less prone to failure than
the conventional optical encoder.� Potential applications include
stepper-motor positioning and anti-stall feedback, DC brush-type
motor positioning, and brushless DC and servo motor control. As
well as being functional in more environments, the M15 is also
designed to accommodate a wide range of motor shaft end play. The
M15 encoder is also available in a wider variety of resolutions
that range from 100 lines up to 2048 lines with 4/6/8/12 pole
commutation and reference pulse options. The core operating module
of the M15 Modular Magnetic Encoder is the proven Timken MPS 160
encoder ASIC (application-specific integrated circuit). The MPS 160
combines a direction-sensing Hall Effect encoder and integrated
index pulse with a high-resolution multiplying circuit to produce
the same quadrature output signals as an optical encoder, and the
encoder ASIC�s patented circuitry provides protection from errant
magnetic fields. The compact Timken encoder, with a low profile of
0.68 inches (17 millimeters), is approximately 1.6 inches (41
millimeters) in diameter and uses industry standard mounting
patterns of 1.28 or 1.81 inches (32.5 or 46 millimeters). The M15
fits numerous shaft sizes making it a convenient drop-in
replacement for more complex optical designs. Timken motion control
solutions include sensor technologies that help improve
performance, extend equipment life and provide precise control in
automotive, off-highway and industrial applications. With a large
product offering including sensor-equipped bearings, condition
monitoring and position sensors, Timken continues to meet motion
control needs globally. About The Timken Company The Timken Company
