Miniature Linear Encoder Kit |
| |
 POSIC
introduces the highly miniaturized inductive linear encoder kit ID1101L.
The encoder-head measures only 9.0 x 6.8 mm with a thickness of 0.9 mm
and provides A and B outputs in quadrature. The linear scale is 3.7 mm
wide and 0.9 mm thick and comes with a length of 200 mm that can be “cut
to length”. The encoder is available in resolutions from 0.3 mm down to
0.3 um. The maximum speed depends on the resolution and ranges from 100
mm/s at a resolution of 0.3 um up to 40 m/s at a resolution of 75 um or
larger. The main features of this kit encoder are its extremely small
dimensions and its insensitivity to dust, water, oil, grease and even
magnetic fields. Typical applications are in the mechatronics and
motion-control domains as speed or position feedback device. Markets
served include industrial, robotics, medical, instrumentation,
laboratory automation, office equipment. ... |

Programmable incremental encoders:
Reduced inventory costs and enhanced flexibility |
| |
 Baumer:
As elsewhere, neither in the incremental encoder field there is an
all-in one allround device that is suitable for every purpose. In
practice, especially complex systems call for diversified configurations
which influence production costs and competitiveness in a negative

varied connection options provide the solution. To keep the product
variety in the individual application field at a minimum, Baumer as a
technology leader offers even four programmable incremental encoders
that utilize optical or magnetic sensing and are available in several
shaft designs. All of them have one thing in common: Convenient
programming either manual or by DIP switch, what is an easy thing to do
even in the most remote corner of the world. Another option is
comfortable parameterization using a PC. The new programmable encoder

Tyco Electronics Reluctance Resolvers for
Hybrid Applications |
| |
|
Tyco
Electronics: New emission legislation and the trend towards energy
efficient transportation support an increased development in the area of
hybrid propulsion for passenger cars. One of the key applications for
improved fuel economy in the hybrid market is the recovery and storage
of energy during the braking phase or regenerative braking. When
braking, the energy of the moving car is converted and stored in the
Li-ion batteries instead of being dissipated through the heating of
braking disks. Upon acceleration of the car, the available electrical
energy is used to help the car speed up by releasing this energy into a
controlled electrical motor. More advanced systems may continuously
propel the cars’ electrical motors. In order to keep the efficiency of
the electrical hybrid motors at a maximum level, the position of the
drive shaft must be continuously monitored. Tyco Electronics has
developed a break-though inductive sensor, known as a “Reluctance
Resolver,” that can help support reduced fuel consumption with in these
new hybrid propulsion systems. The Reluctance Resolver is part of a
system to measure shaft angles. ... |

Baumer
encoders are designed for utmost reliability under most adverse
conditions, and the many decades of dependable operation in customer

where trust is not enough – regardless of most reliable technology.
Baumer has taken this aspect into account and embedded a
function-checking system in their new encoder series HOG 9.2 and HOG
10.2 (fig. 1). Identical in mechanical design to HOG 9 and HOG 10 that
have proved absolutely reliable in tens of thousands of applications,
the enhanced HOG 9.2 and HOG 10.2 feature the so-called “Enhanced
Monitoring System” (EMS). The basis is a rapid microprocessor which
continuously monitors all encoder functions over the full speed range.
Any eventual malfunction or error is quickly and reliably detected. By
an alarm output the control is informed of any error occurred. The
prevailing operating status is visualized by LED provided at the encoder
housing. But the new HeavyDuty encoders are ... |

Reliable encoders for railway vehicles |
| |
|
Baumer
Electric: With its BMIV line, Baumer presents an encoder designed
for the harsh operation on railway vehicles. Multiple channel outputs
allow simultaneous wheelset speed information to multiple systems, also
with differing pulse rates. These include systems for slide control,
speed and slip regulation as well as those to suppress torsion
vibration. The demands made of encoders for railway vehicles are
enormous. They must remain completely unaffected by extreme
environmental influences such as dirt, oils, grease, spray water,
condensation, large temperature differences as well as high and low
temperatures. High shock and vibration loads resulting from the direct
encoder installation on unsprung pivoted bogies are a particular
challenge. All Baumer encoders for railway vehicles operate on the
proven MAGRES principle. This magnetic sensing method offers extreme
reliability and is totally resistant to all loads encountered during
railway operations. Aside from compliance with all railway standards,
the BMIV also offers SIL 2 certification. Baumer has decades of
experience in sensors intended for use with railway vehicles. Thanks to
close cooperation with our customers coupled with continuous
innovations, we are able to offer tailor-made solutions using the latest
technology and offering the highest level of customer benefit. ... |

Magnetic Rotary Encoders for HeavyDuty
Applications |
| |
|
Baumer:
In the field of drive engineering, measured value acquisition poses
increasingly difficult challenges when it comes to dynamics and
precision. These two generally conflicting requirements are difficult to
unite when using conventional rotary encoders. If, in addition, sensors
need to be robust enough to be used in the toughest operating
environments, new solutions and approaches are required. For
applications like these, Baumer Hübner, a German-based company
specializing in rotary encoders, produces robust, specially engineered
encoders, that use a magnetic sensing method, combined with complex
interpolation and evaluation electronics. These enable position, speed
and other variables like acceleration to be measured synchronously, and
deliver both high-dynamic and high-resolution readings. The encoder
rotor can be supplied with a diameter of up 800 mm and can be
screw-mounted straight onto a drive shaft or attached with a clamping
ring or clamping fixture. Encoder rotor and dedicated sensing head are
of short axial length and can be adapted easily to existing fittings.
Thanks to the interpolation electronics, measured value acquisition can
be customized ... |

4B Rotech Encoder |
| |
|
The
4B Rotech Encoder is used primarily for protecting equipment and
personnel from dangerous underspeed / belt slip conditions. Other
applications include accurate speed control, direction of rotation
detection, gate position indication and counting the number of
revolutions of the shaft. An inductive sensing device in the body of the
encoder detects a steel rotor. On slow speed or accurate position
control, a photo diode detects the slots on a steel disk. One pulse is
created for each rotor or slot so the unit can be connected directly to
a PLC/computer or 4B control module. The shaft to be monitored is
drilled and taped to take the M12 Rotech Bolt. No guards are required as
the rotating components are encased inside the aluminium housing of the
encoder. No brackets are required as the encoder couples directly to the
end of the shaft and floats with the shaft. Polyester and stainless
steel versions are also available for offshore and other highly
corrosive applications." ... |

Penny
+ Giles has launched an upgrade to its popular SRH280 contactless
rotary position sensor. The new SRH280P incorporates a factory
programmable Hall effect rotary sensor to provide reliable and accurate
rotary measurement in extreme motorsport environments, such as steering
position monitoring, throttle position sensing and suspension feedback.
The sensor is also highly suited to a wide range of other industrial
applications. Unlike potentiometer sensors, the SRH280P can operate in
high dither vibration conditions with no deterioration of the sensing
element due to the non-contacting operating principle. As a result it
