1 For your safety
1.1 Appropriate use
The described plug connectors are accessory parts for continuously
measuring sensors.
They are used for separable connection to power supply/signal pro-
cessing for two-wire sensors. Those are sensors whose power supply
as well as measurement signal are transmitted over one pair of wires.
1.2 Impermissible use
As a rule, it is not allowed to use plug connectors with four-wire instru-
ments.Those are sensors whose power supply and measurement
signal are transmitted over two separate pairs of wires.
1.3 General safety instructions
The safety information in the operating instructions manual of the
respective sensor must be noted.

– This supplementary instructions manual
The plug connector is an accessory part for sensors with single or
double chamber housing. It is used as separable connection to power
supply and signal processing.
The plug connector consists of the screwed housing, the connection
cable to the sensor electronics as well as the connector housing.The
individual cores of the connection cable are marked with gures for
the terminals of the electronics module.The connector housing is
available in straight and bent version.
