2.1 Intended use
The BMP Magnetic Field Positioning System, together with
a machine control system (e.g. PLC) and IO-Link, master
forms a position measuring system. It is intended to be
installed into a machine or system and used in the
industrial sector. Flawless function in accordance with the
specifications in the technical data is ensured only when
using original Balluff accessories. Use of any other
components (with the exception of cylinders) will void the
warranty.
Opening the BMP or non-approved use are not permitted
and will result in the loss of warranty and liability claims
against the manufacturer.
2.2 General safety notes
Installation and startup are to be performed only by
qualified personnel with fundamental electrical expertise.
Qualified personnel are those who can assess assigned
tasks, recognize possible hazards and initiate appropriate
safety measures based on their professional training,
knowledge, experience and understanding of relevant
regulations.
The operator is responsible for ensuring that local safety
regulations are observed.
In particular, the operator must take steps to ensure that a
defect in the BMP will not result in hazards to persons or
equipment.
If defects and unresolvable faults occur in the BMP, take it
out of service and secure against unauthorized use.
2.3 Explanation of the warnings
Always observe the warnings in these instructions and the
measures described to avoid hazards.
The warnings used here contain various signal words and
are structured as follows:
SIGNAL WORD
Type and source of the hazard
Consequences if not complied with
►Measures to avoid hazards
The individual signal words mean:
NOTICE
Identifies a danger that could damage or destroy the
product.
CAUTION
The general warning symbol in conjunction with the
signal word CAUTION identifies a danger that could lead
to slight or moderately serious injuries.
DANGER
The general warning symbol in conjunction with the
signal word DANGER identifies a hazard which, if not
avoided, will certainly result in death or severe injury.
2.4 Disposal
►Observe the national regulations for disposal.

3.1 Construction
Electrical connection: The electrical connection is made
via a cable with or without a connector (see type code on
page31).
Housing: Aluminum housing with plastic closures.
Housing length: Measuring range + 10mm.
Attachment: Holes are provided in the BMP for
attachment using M2 mounting screws or slot nuts (see
accessories on page30).
Target: Defines the position to be measured.
Measuring range: For adapting the BMP to the
application optimally, the following measuring ranges are
available: 32/64/96/128/160/192/224/256mm. The values
listed in the Technical data (see Sec.8.1 on page29)
are maintained for repeat accuracy and non-linearity.
Detection range: Range in which the BMP detects the
position of the target. It extends beyond the measuring
range by 4 mm on both sides.
The detection range which goes beyond the
measuring range is only output via the IO-Link
interface.
3.2 Function
The BMP is an intelligent magnetic field positioning system.
It is used primarily for the non-contact detection of the
piston stroke of pneumatic cylinders, grippers and slides
with axially magnetized permanent magnets. The BMP
ensures continuous, absolute position measurement at an
application-relevant level of measuring accuracy.
The analog output of the BMP is easy to evaluate and can
be switched between voltage and current. It also offers a
switching output that is easy to adjust.
Using the button and the three LEDs, the BMP can be
configured without addition auxiliary tools.
Over the IO-Link interface, the BMP offers additional
configuration options and state monitoring functions.
The functions of the BMP allow it to support simple format
change in different applications.

3.2.1 Analog and switching output
Analog output
– Switchable between:
– 0…10V (output value outside of the configured
measuring range: 10.5V)
– 4…20mA (output value outside of the configured
measuring range: 3.5mA)
– Start and end point of the measuring range are
adjustable.
– 12-bit resolution (adjusted to the configured measuring
range)
Switching output
– Adjustable switch-on and switch-off point
– Measuring range display is a factory setting (active over
the entire measuring range)
– Normally open/normally closed (switchable)
Analog and switching output are described in Chapter6
on page15.
3.2.2 IO-Link interface
– Absolute measured value (μm)
– Measuring range display via status bit
– Four switching signals
– Extensive configuration options for the measured value
and switching signals
– Functions for state monitoring:
– Temperature detection
– Operating hours counter
– Boot cycle counter
The IO-Link interface is described in section7 on
page17.

There are three available variants for installation:
– Attachment to a pneumatic cylinder using a C- or T-slot
(see section4.1).
– Attachment to a round cylinder using hose clamps and
round cylinder holders (see section4.2).
– Mount the BMP to a surface using mounting screws
and operate it with floating target (see section4.3).
Important installation notes
CAUTION
Increased housing temperature
In the event of insufficient heat coupling due to the
mounting, the surface temperature of the BMP can
increase and cause burns when touched.
►Correct the heat coupling of the installation.
►Reduce the load.
NOTICE
Interference in function
Improper installation can compromise the function of the
BMP and result in increased wear.
►The target must not contact the BMP.
►Shield any magnetic fields that can influence the
measurement.
Position the BMP so that the measuring range can detect
the entire range of movement of the target.
The target must be polarized axially. The orientation (whe-
ther the cable end points in the direction of the North or
South Pole) does not matter.
The position detected by the BMP is in the middle of the
target.
Only the cylinder which has a permanent magnet installed
as the target is eligible when mounting to a pneumatic
cylinder.
A rotating cylinder head causes inaccuracy that is too
large!
For fastening screws and slot nuts, see
Accessories on page30.
