Working Principle The extension cable transmits the high-frequency RF signal from the Proximitor sensor to the probe coil and returns the modulated signal reflecting target impedance changes. The 75 Ω characteristic impedance matches the probe and Proximitor, ensuring minimal signal reflection. The FluidLoc layer prevents machine fluids from wicking along the cable interior, preserving dielectric properties and preventing short circuits.
Installation Requirements
- Total system electrical length must match the Proximitor sensor calibration
- Minimum bend radius must be observed to prevent impedance changes
- Route away from high-voltage power cables
- Secure with cable clamps at intervals to prevent fatigue
- Do not stretch or mechanically load the cable beyond rated pull strength
Usage Precautions
- Verify connector mating torque to prevent intermittent connections
- Inspect jacket integrity before installation in fluid-exposed areas
- Do not splice or shorten the cable
- Store coiled loosely to prevent memory kinks
- Replace if the jacket shows signs of abrasion or chemical damage
