With more than 40 years of experience in the field of sensor
technology, Balluff is today one of the most capable manufacturers
of electronic and electromechanical sensors, rotary and linear
transducers as well as identification systems. Innovative technology,
state-of-the-art electronics and application-specific customer
solutions are the hallmarks of the entire product range.
Balluff inductive sensors are used for controlling, regulating,
automating, positioning and monitoring of work processes. They are
rugged sensors which detect the presence of a metal part.
They operate without contact and have an electronic output, i.e.
they are wear-free. Applications include machine tools, plastics
machinery, textile machines, assembly lines, in the automobile
industry, in wood processing machinery, in other words everywhere
processes need to be automated.
The wide-ranging optosensor line from Balluff finds applications in
all areas of automation. Every series has its main strength and is
an outstanding specialist in its area of application.
Along with tubular housings from M12 to M30, in both metal and
plastic, Balluff also offers a range of sensors in rigid,
block-shaped plastic housings in nearly all sizes with various
functions and performance characteristics. Along with the classic
diffuse, retro-reflective and through-beam -beam types, the Balluff
opto line also offers special functions and versions.
Analog Sensors BAW have a linear voltage or current output signal
which changes in proportion to target distance from the damping
surface. The curve is linear over the entire working range SI.
Balluff Micropulse transducers in the Profile housing, with their
mechanical design, the high protection rating, and their ease of
installation, are an alternative to linear transducers such as
potentiometers, glass scales, and LVDTs. The linear sensing element
is protected in an aluminum extrusion. The measuring point along the
sensing element (waveguide) is indicated by a passive marker (magnet),
which needs no power.
Balluff identification systems are indispensible tools for managing
the flood of information in today's assembly operations. The right
data at the right time at the right place: These demands are met by
integrating the BIS system, as each material flow object.
The code tag stores all the information about the object, ready for
reading or updating at any point in the process. Whether you're
talking about complex assembly instructions, complete test records,
or just a 4-digit identification number: you will find the most
economical and efficient solution from among the broad range of BIS
identification systems.
Electromechanical sensors include electromechanical limit switches
as well as rotary cam switches with electromechanical and/or
inductive switch elements. They serve as non-contact command givers
with automatic controls for positioning and limit switching on
machine tools, flexible manufacturing equipment, robots, assembly
and conveying equipment, in the automobile industry, as well as
general machinery and equipment applications.
They have been designed and proven for use under extreme conditions
such as shock, aggressive media like cutting and lubricating fluids,
as well as temperature fluctuation.
Magnetic field sensors respond to an external magnetic field. They
are used primarily to sense piston positioning in pneumatic
cylinders. Housing materials are polyamide, PBTP reinforced
fiberglass or aluminum, depending on the sensor selected. Mounting
clamps are also available for attaching to virtually any cylinder
size and type!
Capacitive sensors detect the change in capacitance of an object
when it enters the sensor's electrical field. This means a
capacitive sensor can detect not only metal, but even non-conductors
whose dielectric constants are sufficiently large. Properly selected,
a capacitive sensor is also able to "see through" certain
non-metallic materials.
This makes it the classical level detector, sensing the presence of
absence of liquids or granular material through the container wall.
Balluff also offers the appropriate cover nuts which, once installed
in the container, allow the capacitive sensor to be mounted and
later replaced if necessary without unsealing the vessel.
The use of remote systems is a proven solution wherever hardwired
sensors cannot be used, such as on indexing tables and
interchangeable stamping heads. The sensors participate in the
motion of the machine components to which they are attached. The
sensors are wired to the transmitter.
The transmitter however is only inductively coupled to the output
sensor. The transmitter sends the output signals from the connected
sensors to the output sensor. The energy required to power the
sensors is inductively coupled from the output sensor to the
transmitter. The latter in turn supplies the connected sensors with
operating voltage.
