The sensor demodulates the signal changes caused by target surface eddy currents into a proportional DC and AC voltage output. For an 11 mm probe system, the calibrated linear scale factor is 3.94 V\/mm (100 mV\/mil). During installation, static mechanical positioning requires gap voltage validation at the sensor output terminals. The technician sets the probe gap to achieve a nominal -10 VDC bias target, corresponding to the physical midpoint of the sensor linear operating range over carbon steel targets.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Why must the Proximitor Sensor remain matched to a 5.0 meter system cable length?\u003c\/p\u003e\n\u003cp\u003eA: The internal oscillator and signal conditioning circuitry are tuned for a total system capacitance corresponding to 5.0 meters. Altering the physical cable length without recalculating tuning distorts the linear scale factor.\u003c\/p\u003e\n\u003cp\u003eQ: What is the electrical requirement for supply power to the 330780 Proximitor Sensor?\u003c\/p\u003e\n\u003cp\u003eA: The unit requires a negative DC supply voltage between -17.5 VDC and -26 VDC referenced to system ground, drawing a maximum current of 12 mA.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eSnap the Proximitor Sensor housing securely onto a standard 35 mm DIN rail inside an IP65 or NEMA 4X rated field enclosure.\u003c\/li\u003e\n\u003cli\u003eVerify electrical isolation between the Proximitor base housing and the mounting plate to avoid unintended ground loops.\u003c\/li\u003e\n\u003cli\u003eConnect the 11 mm proximity probe extension cable to the Proximitor coaxial connector, ensuring the ClickLoc keyway is fully engaged and hand-tightened.\u003c\/li\u003e\n\u003cli\u003eApply coaxial terminal insulation boots over the physical connection to isolate the coaxial outer conductor from local ground contact.\u003c\/li\u003e\n\u003cli\u003eConnect field wiring to the screw terminal block: -24 VDC power, Common, and Signal Output.
