4B P300 Series, Руководство по эксплуатации

Страница: 8 / 16

The P300 should be wired as shown in the connections diagram on page 10.
The P300 Proximity Switch must be wired through a load/resistor (see standard wiring diagram) and not
directly to supply voltage. The supply polarity is not important and the load can be connected in either wire.
Different P300 models have different connections, so make sure to use the correct diagram for your model.
Cable length can be extended to virtually any distance required. The proximity sensor is well protected
against electrical interference, but if long cable runs are used in very noisy environments, the cabling
should be segregated from any high current carrying and ideally shielded cables should be used for long-
distance runs.
Red LED (output) indicates target sensed.
IMPORTANT:
The sensing face of the sensor, should overhang at least 30mm from any metalwork that the unit is fixed
to, otherwise the unit will stay in the “ON” state. Ensure that any background metalwork, behind the target
to be sensed, is at least 15mm behind the target. This will prevent the proximity sensor from detecting that
background metalwork. Illustration A below denotes sensing ranges for ferrous and non-ferrous targets.
