HEIN LANZ has recently launched
the magnetic rotary encoder with programmable
functions which are suitable for severe
environments. It is well known that magnetic
encoders have been unable to achieve the high
accuracy and high dynamic analysis performance
of photoelectric rotary encoders since being
launched onto the market. However, this
disadvantage has also hindered its application
in industries where high accuracy and high
dynamic analysis performance are widely
required, and it even becomes impossible to make
use of the advantages of its mechanical
properties such as its high protection grade and
strong impact resistance.
Thanks to pioneering European
research and development in magnetic sensors,
and by equipping the customized Hall sensor and
the 32-bit high speed processing chip with
powerful functions, HEIN LANZ has completely
overcome this difficulty. Thanks to these two
state-of-art technologies, the HEIN LANZ
magnetic encoder can now access data in several
microseconds. It is the first time that its
electric performance has matched that of the
photoelectric rotary encoder, enabling it to
play a significant role in various kinds of
severe environments thanks to its excellent
mechanical properties.
Product features:
■ Resistant to salt water
corrosion
■ Compact in size, with a diameter of 36 mm
■
Compatible with many kinds of installation modes
such as shaft and sleeve installation
■ Contactless measuring
■
Protection grade up to IP69K
■
Single-turn resolution and number of turns up to
32 bit
At present, the HEIN LANZ
magnetic absolute value encoder can provide
single turn and multi turn products. The output
interface includes: analogue (4…20mA, 0…20mA,
0…5V and 0…10V are available as an option), SSI
(synchronous serial interface) and CAN open bus
communication. Selection of various kinds of
data communication interfaces makes it possible
to connect seamlessly with various types of
controllers.
The accuracy of the product is
very high - the maximum resolution of a single
turn is 16 bit, and the maximum number of turns
is 20 bit (resolution of single turn + number of
turns ≤ 32 bit). Its accuracy can reach 0.005°,
and the maximum number of detectable absolute
positions is 4,294,967,296. Its capabilities
have been fully verified for use in industries
such as medical apparatus & instruments and
laboratory equipment, where highly accurate
positions or angular control are required, and
where the installation area must be taken into
account. What's more, the increment output can
also be attached to this product, which allows
for two applications with one device when
compatible with position measuring and speed
measuring. Not only does this reduce the number
of components and costs for the client, it also
minimizes the fault points in the system. It can
therefore be described as worry-free and
cost-efficient.
The development of magnetic
technology enables the product to operate stably
at low temperatures. HEIN LANZ products can
operate normally at an ambient temperature of
-40°C. This feature together with the high
protection grade of the product effectively
eliminates the problem that common photoelectric
encoders have of not being able to operate at
low temperatures in outdoor environments. In
addition, we can also provide products made of
316L stainless steel. It is salt water
resistant, has a protection grade of IP69K, and
has axial and radial loads of up to 300N,
allowing it to operate with heavy offshore
equipment perfectly.
The Novel HEIN LANZ magnetic
absolute encoder has many advantages and takes
various performance requirements such as
mechanical strength, detection accuracy, and
electrical interface into consideration. It is a
pioneering encoder product of this industry.
