The P300 is an inductive sensor designed to detect shaft speed, shaft position, gate position, or object
presence. No contact is made between the sensor and the object being monitored.
Maximum range of ferrous targets is 8 mm (5/16”) and for non-ferrous targets is 5 mm (6/16”), assuming a
20 mm (3/4”) diameter target. Smaller targets may be used but operating distances will be reduced.
different sensor outputs are available.
P3003V10AI and P3004V10AI sensors have a two-wire interface and have an internal transistor which
either switches to open or closed state when target is present (see page 10). P3003V34AI has an isolated
transistor and the output is determined by the orientation of the positive and negative supply connections
All units are fully encapsulated and come with a 3m cable lead. Two LED’s show power supply and input

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-
Red LED (output) indicates target sensed.
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.

Ensure all connections are correct before applying power. Apply power to the P300 and machinery, then
check that the output LED is flashing when the target is being sensed.
It is crucial that all exposed rotating shafts are provided with a full guard. Therefore, this device and its
target must be equipped with a guard.

STANDARD WIRING DIAGRAM
All wiring must be In accordance with local and national electrical codes and should be undertaken by an
experienced and qualified electrician.
Where necessary, use dust/liquid tight flexible metal conduit with approved fittings to protect the sensor
cables. Use rigid metal conduit to protect the cables from the sensors to the control unit. Conduit systems
can channel water due to ingress and condensation directly to sensors and sensor connections which
over time will adversely affect the performance of the system. As such, the installation of low point conduit
drains is recommended for all sensors.
1500A capable fuse with 500mA maximum rating
be used for each sensor in order to comply
with ATEX wiring regulations.

Note: NPN, Energised (top left) is the standard wiring to use this sensor with all the 4B controllers.
If the system does not immediately shutdown as expected or alarm as required, then remove the
machine from service until the problem has been diagnosed and corrected.
TESTING AND COMMISSIONING
1. Check that the unit is correctly installed (see standard wiring diagram).
2. Check that the distance between the target, stud or bolt head and sensing face of P300 is within the
minimum distance specified.
3. Start up machine.
4. If monitoring for speed see A, for proximity monitoring see B -
A. If the P300 is being used to monitor speed, 4B’s
Master™ calibration and testing device
can be used to insure the P300 shuts down the machine at the correct percentage of slip. Shut
down will depend on your specific monitoring setup. 4B recommends an instant shutdown on any
belts slipping 20% or more of normal speed.
B. If the P300 is being used as a proximity switch, be sure that the target is not within range of the
sensor prior to testing. Use a metal putty knife or a small piece of metal and place it between the
sensing face of the P300 and the target. This will cause the sensor to energize the output, and
both the green and red LEDs will go on. Removing the putty knife will de-energize the output
signal and both LEDs will go off.
Master™ with Pulse Pilot is the only device that
accurately tests the calibration of a speed switch, and allows
testing of the alarm and shutdown features of the sensor while
installed on the machine shaft.
Master™ operates in two modes. Input mode is used
to measure the pulse rate at normal speed. Output mode will
allow the user to input pulses to the sensor for testing purposes.
The Pulse Pilot fits between the gap between the sensor and
the target. The Pulse Pilot will have no effect on the operation
of the speed switch until it is connected to the
and set to “output” mode.
LED Stays “ON”
• Check that the sensing face of the sensor is not bolted directly to metalwork
• Check that there is a space between the sensor face and any surrounding
metalwork (30mm minimum)
• Check that the machinery is rotating and that the target is actually leaving the
sensor before reappearing
• Check that background metalwork, behind target, is far enough away so as
not to be detected
LED Stays “OFF”
• Check supply voltage to the sensor.
Check that target is within specified operating range of unit.
• Check that machinery is rotating and that target is passing the sensing face
of the sensor.
