Product description
The POMUX KH53 non-contact linear encoder can measure absolute lengths up
to 1,700 m. The encoder consists of two
main components: The non-contact read
head determines the absolute position
using a series of measuring elements
attached along the measurement path.
Each measuring element consists of a
number of permanent magnets. Since
the distances between the magnets are
unique, they can be used to develop an
absolute measuring code. No reference
At a glance
• Non-contact length measurement
– maintenance-free, rugged, long
service life
• High reproducibility (0.3 mm / 1 mm),
high system resolution (0.1 mm)
• SSI and PROFIBUS interfaces
• Determination of absolute position
• Measuring lengths of up to 1,700 m
possible
Your benets
• After installation, the system is
immediately available and completely
maintenance-free, which leads to time
and cost savings
• Reliable determination of position
under harshest ambient conditions
such as the effects of dirt, dust, fog,
shock, and vibration
run is required due to the absolute position being determined. The read head
is passed parallel to these measuring
elements at a distance of 25 mm or
55 mm. With a measuring length of
up to 1,700 m, the KH53 is ideal for
use in cranes, in storage and conveyor
systems, and for railed vehicles. Due to
the non-contact technology, this system
works wear-free even in harsh ambient
conditions,so that a long lifetime is
ensured.
• Can be used in the harshest ambient
conditions
• High traversing speedds of up to
6.6 m/s
• Distance tolerance between read
head and measuring element: up to
55 mm ± 20 mm possible
• High efciency and productivity levels
• Time savings – no reference run nec-
essary on initial commissioning due
to absolute position measurement
• Accurate positioning even with high
mounting tolerances

Related to the start of a measuring element if a position tolerance of ± 1 mm is maintained based on the nominal distance in the N and Y directions. ME = Length of
the measuring element (see illustration on page J-652), Tu = ambient temperature in °C, Tk = coefcient of thermal expansion (see "Mechanical Data" table on page

Calculation example for a measurement distance of 100 m
Selected system with measuring range up to 107 m
Number of measuring elements required = measurement path + length of the read head / length of measurement element (according to table above)
Number of measuring elements required = 101.051 m / 1.8688 m = 54.07
Ordering amount therefore 55 measuring elements and 55 * 3 = 165 clamp holders
If two separate measurement paths are to be implemented, then please order 2 x 55 measuring elements (not 110 measuring elements)
Attention! For position determination, the read head must not travel beyond the last measuring element.
