Intended use
The BTL7 Micropulse Transducer, together with a machine 
controller (e.g. PLC), comprises 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 will void the warranty.
Opening the transducer or non-approved use are not 
permitted and will result in the loss of warranty and liability 
claims against the manufacturer.
General safety notes
Installation and startup may only be performed by 
trained specialists.
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 position 
measuring system will not result in hazards to persons or 
equipment.
If defects and unresolvable faults occur in the transducer, it 
should be taken out of service and secured against 
unauthorized use.

Dimensions and function
The transducer contains the waveguide. A magnet is 
moved along the waveguide. This magnet defines the 
position to be measured on the waveguide.

NOTICE!
Improper installation
Improper installation can compromise the function of the 
transducer and result in damage.
 ► For this reason, ensure that no strong electrical or 
magnetic fields are present in the immediate vicinity 
of the transducer.
 ► The recommended spacing for the installation must 
be strictly observed.
Any orientation is permitted. Mount the transducer on a 
level surface of the machine using the provided mounting 
clamps and cylinder-head screws. A sufficient number of 
mounting clamps is supplied.
In order to avoid the development of resonant 
frequencies from vibration loads, we 
recommend arranging the mounting clamps at 
irregular intervals.
