ASM Position Sensors
The company and the products
ASM has played an active role in the manufacture of position
sensors for 25 years.
In order to solve all kinds of linear and angular measurement
tasks in industry and research, ASM currently offers three different types of positional sensor technology:
• POSIMAG®
Magnetic measuring scale with MR sensor head.
Thanks to its special properties, POSIMAG® is ideal for many
industrial applications in the production of machinery, plants
and precision equipment as well as research. POSIMAG® is
suitable for linear, angular and speed measurements. The magnetic scale can also be applied to uneven surfaces.
• POSICHRON®
Magnetostrictive principle (Time of Flight).
The areas of application for POSICHRON® positional sensors
are wide and varied. They are used in e.g. injection-moulding
equipment, dosing and mixing systems, die-casting machines, road vehicle tests, tunnel-boring equipment, wind power
plants, patient beds, hydraulic cylinders and presses, fill-level
measuring equipment etc.
• WS
Cable actuated position sensors.
WS position sensors ensure reliable operation in many sectors
of automation, process engineering, industry and research, e.g.
in handling systems, circular saws, printing presses, aircraft
testing, automobile testing, elevator technology, conveyor belt
technology, warehousing technology, local transportation vehicles, tunnel-boring machinery, wind power plants, rehabilitation technology, medical engineering, patient beds, etc.
ASM Position Sensors offer superlative quality and precision.
Ongoing research and development in our laboratories, coupled with comprehensive quality management, facilitate and
safeguard these high standards.
Position Sensors from ASM are used wherever path, distance,
position or length measurements need to be automated, checked, tested or monitored. The customer base includes users
from all sectors of government, industry and research.
With around 80 employees at its headquarters in Moosinning
near Munich, the company manufactures both standard products and customised, specialist solutions. Thanks to the sales offices in Great Britain, Germany, France and a worldwide
network of representatives, sales engineers for ASM products
are never far away and will be delighted to demonstrate ASM’s
range of position sensors at customer premises.

POSIMAG® Position Sensors
POSIMAG® –
the functional principle
POSIMAG® is a contact-free, high-resolution magnetic
position measuring system for measuring lengths of up
to approx. 30 metres. Because of its sturdiness and resistance to dirt, together with the system’s exceptional
resistance to wear and tear, POSIMAG® is also suitable
for use under challenging environmental conditions.
POSIMAG® consists of a magnetoresistive (MR) scanning head, and a magnetic measuring scale that consists of a flexible steel strip with a magnetic carrier layer
laminated on top. This is magnetised at regular intervals
with magnetic north and south poles. The measuring
scale can be fastened in position using special adhesive fixing strip or also using pre-produced assembly rails
with fastening straps. To protect against external mechanical influences, the magnetic scale has a covering
laminate layer made from a thin, stainless steel strip.
To capture a position, the magnetoresistive (MR) sensor
head samples sinusoidal magnetic fields above the magnetic measuring scale in such a way that the process
is contact-free and avoids wear and tear. The distance
of the MR sensor head to the surface of the magnetic
scale can be up to 2 mm in the case of a scale with a 5
mm magnetic spacing. The sine-cosine signals generated in the sensor head, which are displaced by 90°, are
output without any time delay as RS422-compatible impulse signals via the integrated interpolation electronics
working in conjunction with the reference signal. Resolutions of up to 5 µm are available as standard. The signals can then be processed by all common industrial
control units with suitable signal processing speeds, or
displayed directly using a digital display unit from ASM’s
PRODIS series.

● Distance between the MR sensor head and the
magnetic scale up to 2 mm
• Reference and terminal position signals
• Measuring lengths of up to 30,000 mm
(up to 50 m on request)

WS Cable Actuated Position Sensors
WS Position Sensors –
the functional principle
WS position sensors capture position measurement
either absolutely or incrementally, using measuring cables made from stainless steel. Using different constructions, and with measuring lengths of up to 60,000 mm,
the ultra-simple, sturdy, space-saving designs make
these sensors the ideal basic solution for many length
and positional measuring tasks.
WS position sensors comprise the following components:
• A precisely-calibrated measuring cable
• A measuring cable drum
• A measurement shaft
• A spring motor
• An angle sensor element
• Optional sensor electronics.
The measuring cable is first wound in tight spiral layers
round the drum. To determine the position, the measuring cable is then unwound from the drum against the
return force of the spring motor. The unwinding process from the drum converts the linear movement of
the measuring cable into an angular movement. This
angular movement is then captured using angle sensor
elements (encoders or potentiometers) and converted
into an electrical output signal.
Analogue output types include potentiometer, 0-10 V,
4-20 mA, analogue derived SSI or a programmable
version with span and offset adjustment. Digital outputs
include incremental encoder, absolute encoder, SSI,
CANopen, Profibus, Interbus-S or RS-232.
Technical advantages:
• Fast and easy to assemble
• Only minimal linear guidance required
• Compact design
• Resistant to vibration and shock
• High protection category to IP67
• Linearity of up to 0.01%
• High measuring speed up to 20 m/s
• Measuring lengths of up to 60,000 mm
• Many output types

POSICHRON® –
Magnetostrictive Position Sensors
POSICHRON® –
the functional principle
POSICHRON® is an absolute, contact-free and wearfree position measuring system. It is extremely sturdy
making it suitable even for applications where other
measuring principles would fail. The availability of various constructions - rod, square profile and ultra-flat
profile - means that the system can be adapted to suit
all kinds of installation conditions.
The POSICHRON® linear measuring system consists
of a magnetostrictive wave guide and a movable magnet for determining position. The measuring principle of
POSICHRON® position sensors is based on two physical effects: the Wiedemann effect and the Villari effect.
To create the Wiedemann effect, a current impulse is
sent through the POSICHRON® positional sensor’s
wave guide. This current impulse generates a circular
magnetic field which propagates at the speed of light
around the wave guide. If this circular magnetic field
makes contact with the magnetic field of the position
magnet which is moved lengthways, a torsional mechanical-elastic density wave is triggered at the overlap
area of the two magnetic fields as a result of magnetostriction. This wave propagates in the POSICHRON®
positional sensor at ultrasonic speed.
The sensor head of the POSICHRON® position sensor contains a detector which detects the arrival of this
wave. The magneto-elastic Villari effect is used as the
method of detection. The position between the detector
coil and the magnet which can be moved lengthways
along the POSICHRON® sensor is determined by
measuring the time difference between the electrical
induction current impulse and the voltage pulse generated via the Villari effect in the detector coil (time-offlight principle).
This time difference can be converted using various
well-known methods into analogue or digital output signals. The time-of-flight signals can however also be
evaluated directly by commonly-available interface modules or counter and time-measuring devices.
A separate detailed catalog about POSICHRON® Magnetostrictive Position Sensors is available on request.
