WARNING • Rotating machinery can cause serious injury or death • Always lockout and tagout the machine prior to installation PRODUCT OVERVIEW 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.

4. If monitoring for speed see A, for proximity monitoring see B - A. If the P300 is being used to monitor speed, 4B’s SpeedMaster™ 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.
TROUBLESHOOTING GUIDE FAULT REMEDY • 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) LED Stays “ON” • Check that the machinery is rotating and that the target is actually leaving the sensor before reappearing •...
