4.3.5
Supply Voltage
Nominal value: 24 V DC (11 ... 30 V, P < 6 W).
►
Only turn on the power supply after wiring has been completed.
►
Connect inputs "9" and "2" on the 12-pin M12 female connector to a 24 V power supply

Voltage supply only for measuring devices, not to be used for drives or similar sources of impulse interference at the
same time. Micro-Epsilon recommends using an optional available power supply unit PS2020 for the sensor.
4.3.6
Analog Output
The sensor offers the following alternatives:
A 4 ... 20 mA current output
●
A 0 ... 5 V or 0 ... 10 V voltage output
●
i
The current output must not be used continuously in short-circuit operation without a load. Continuous
short-circuit operation leads to thermal overloading and thus causes the output to switch off automati
cally.
►
Connect outputs 1 (white, inner coaxial conductor) and 2 (black, coaxial shield) on the 12-pin M12 female connector
to a measuring device.
