Installation Instructions

1. Mounting the Probe
   Select a mounting location with a clear line of sight to the shaft or surface. Ensure the 3/8-24 UNF thread is clean and secure the probe into a threaded hole or bracket using a torque wrench (recommended torque: 3.5 Nm).

2. Gap Adjustment
   Set the initial gap between the probe tip and target surface to approximately 1 mm (40 mils). Fine-tune using the proximitor sensor’s voltage reading.

3. Extension Cable Routing
   Route the extension cable carefully, avoiding bends tighter than 25 mm radius. Use cable clamps where necessary and avoid electromagnetic sources.

4. Proximitor Sensor Connection
   Connect the extension cable to the matching proximitor sensor. Ensure correct polarity and secure connections.

5. System Check and Calibration
   Power up the system, check output signal stability, and calibrate the sensor using a calibration target or dial gauge if required.
