BTL PA0400- _ _ _ _ -B15A_010-000S92
Magnetostrictive Linear Position Sensor – Profile Style
Installation
NOTICE
Improper installation
Improper installation can compromise the function of the
BTL and result in damage.
► Ensure that no strong electrical or magnetic fields
are present in the direct vicinity of the BTL.
► Be sure to maintain the specified distances and
separations.
For dimensions, see figure.
Observe the following when installing the magnet:
–
To ensure the accuracy of the magnetostrictive linear
position sensor, fasten the magnet to the moving
member of the machine only using non-magnetizable
screws (stainless steel, brass, aluminum).
–
The moving member must guide the magnet on a
parallel line to the BTL.
–
Distance A between the magnet and parts made of
magnetizable material must be kept to at least 10 mm
(see figure).
For distance B between the magnet and the BTL and for
the center offset C (see figure) the following values must be
maintained:
Magnet type
BTL6-A-3800-2
BTL6-A-3801-2
1) The selected distance must remain constant over the entire stroke
length.
2) For optimal measurement results: 6...8 mm
The BTL is installed on a flat surface of the machine using
mounting clamps or cuffs (available accessories). Any
orientation is permitted. Note the recommended spacing
for the location of clamps or cuffs (see figure).
1. Slide BTL into the mounting clamps or cuffs.
2. Align BTL slot in the direction of the magnet(s)!
3. Attach the BTL to the base (tighten screws in clamps
or cuffs to max. 4 Nm tightening torque).
4. Installing magnet (accessory).
5. Check orientation of the BTL. If the groove does not
point in the direction of the magnet, loosen the
mounting screws and repeat steps 2 to 3.

Shielding and cable routing
Defined ground!
The BTL and the control cabinet must be at the
same ground potential.
Shielding
Observe the following instructions to ensure
electromagnetic compatibility (EMC):
–
Connect BTL and controller using a shielded cable.
Shielding: Braided copper shield with minimum 85%
coverage.
–
Shield is internally connected to connector housing.
Magnetic fields
The position measuring system is a magnetostrictive
system. Ensure that there is sufficient distance between
the BTL and the transducer/holding cylinder and strong,
external magnetic fields.
Cable routing
Do not route the cable between the BTL, controller, and
power supply near high voltage cables (inductive stray
noise is possible).
The cable must be routed tension-free.
Cable length
BTL ...-B15AA/A1...
BTL ...-B15AE/A5...
1) Prerequisite: Construction, shielding and routing preclude the effect of
any external noise fields.
Electrical Connection
The electrical connection is made via a plug connection.
See the information about Shielding and cable
routing.
