construction

The threshold detector / temperature transmitter is made of an elec-
tronic module and a measuring element. The electronic module can
be adjusted by 180°.
• The electrical connection of the 8400 threshold detector is made
via an M12, 5-pin fixed male adjustable connector and, depending
on the version, an EN 175301-803 fixed connector.
• The electrical connection of the 8400 transmitter is made via an
EN 175301-803 fixed connector and an M12, 8-pin fixed male
connector.
The 8400 requires a 12-30 VDC power supply.
• Depending on the version, a threshold detector has 1 NPN or
PNP transistor output or 1 relay output.
