TECHNICAL CHARACTERISTICS
The AMD is a NAMUR (DIN 19234) sensor with the following nominal characteristics:
Nominal voltage 8.2 V
Power supply internal resistance 1 k
Ω
Current with the vane into the slot < 1 mA
Current with the vane out of the slot ≥ 3 mA
Power supply limits 5 ... 25 VDC
Ambient Temperature -25 ... +100 ºC
Self inductance 160 µH
Self capacity 20 nF
Conforms with the Directive EMC 89/336/EEC
With the potentiometer we modify the current of the NAMUR amplifier. The switching point must be
between 1.2 mA and 2.1 mA. That is, with the current below 1.2 mA the output relay must have a
state and above 2.1 mA the output relay must have the other state.
