Flybox Inductive RPM Sensor Kit (DBMIIS12KIT)
The Flybox DBMIIS12KIT is a heavy-duty, threaded M12 inductive proximity tachometer sensor kit designed for the Flybox Omnia and Vigilus EIS series. Engineered to count starter ring gear teeth, flywheel lobes, or pulley targets, it provides a noise-free, high-accuracy digital RPM signal without mechanical friction, ignition cross-talk, or wear.
Operational Capabilities & Sensing Precision
Non-contact tachometer telemetry engineered for high-vibration aircraft cowlings:
Non-Contact Inductive Sensing
Reads passing ferrous teeth and bolt heads across an electromagnetic air gap. Completely frictionless design ensures zero mechanical wear, eliminating the drift and failures common in mechanical pickups.
Ignition Noise Immunity
Generates clean square-wave digital pulses directly to the avionics tachometer input, avoiding the erratic RPM needles and false limit alarms associated with spark plug capacitive pickups.
Integrated Alignment LED
Features an on-body status LED that flashes when a gear tooth or trigger point passes the face. Allows effortless gap calibration and verification simply by rotating the propeller by hand.
Impervious to Oil & Fuel
Hermetically potted metal threaded housing resists engine oil splash, avgas, mogas, continuous cowl vibration, and elevated temperatures up to +85°C without signal attenuation.
