Connection of Mahr transducers
The pin assignment for Mahr transducers of the product range P2xxx-M (e.g.:
P2004-M) differs from the pin assignment for standard half-bridge transducers
(e.g. GT21 of Tesa).
Should you want to connect a Mahr transducer to the Box PX3701-HB-x with the
Mahr assignment (Designation M), an adapter between the transducer and the
flange socket of the connection box is necessary.
The Mahr transducers are also available with a Tesa compliant assignment
(Designation T; e.g. P2004-T). This version can be directly connected to the
connection box.
i
IMPORTANT!
Before ordering a Mahr transducer, you have to consider the different types
of the 5-pin assignment.
