Installation

For dimensions, see Fig. 4-1 on page 7.
Suitable nuts for the mounting thread are
available as accessories (see page 17).
NOTICE
Interference in function
Improper installation can compromise the function of the
BTL and result in increased wear.
► Ensure that the contact surface of the BTL is in full
contact with the mounting surface.
► Seal the hole perfectly (O-ring/flat seal).
Mounting in a hole with internal thread (mounting
hole)
1. Make a mounting hole with thread (possibly with
countersink for the O-ring) acc. to Fig. 5-3 or Fig. 5-4.
2. Screw the BTL with mounting thread into the mounting
hole (max. torque 75 Nm).
Mounting in a through-hole
1. Guide the BTL through the hole.
2. Screw the mounting nut (max. torque 75 Nm, see
Accessories on page 17) onto the mounting thread
on the rod side.
Further steps
► Install the magnet (accessory).
► From measuring length of 500 mm: Support the rod
and if necessary screw on at the end.

Electrical Connection

The electrical connection is made via a plug connection
(for pin assignment see Tab. 5-2).

Cable routing

Defined ground!
The BTL and the control cabinet must be at the
same ground potential.
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
All cables between BTL, control and power supply must
be routed tension-free. In order to avoid electromagnetic
interference, ensure sufficient distance to cables carrying a
heavy current and cables with high-frequency voltage
signals (e.g. of frequency converters).
Cable length
For IO-Link operation, the maximum cable length is 20 m.
