Output Stage Parameters
Check that the power supply range limits of the proximity sensor are compatible with the
nominal voltage of the AC supply used.
Where a DC supply is available, check that the voltage limits of the sensor, including ripple, are
compatible with the supply used.
If an AC supply is available, a suitable DC power supply must be selected. A simple one has a
transformer, a rectifier, and a smoothing capacitor.
Where voltage is derived from a single phase AC supply, it must be rectified and filtered to
ensure that:
• The peak voltage of the DC supply is lower than the maximum operating voltage of
• The minimum voltage of the DC supply is greater than the minimum voltage rating of
As a general rule, use a transformer with a lower secondary voltage (Ue) than the required
DC voltage (U).
Example:
Mount a filtering capacitor of minimum 400 µF per sensor or 2000 µF for each ampere of load
current required.
NOTE: Tubular 3 wire DC universal models (10-58 V), 3 wire DC XSF models, and all AC/DC
models can be supplied from full-wave rectified non-filtered (no capacitor C in the diagram
above) power supplies.
