4AV19F Impeller sensor Hall effect, max. 0.40 V DC

AV series impeller-driven position sensors with integrated magnets are operated with a ferromagnetic vane that passes through the gap between the Hall sensor and the magnet, so that the magnetic flux is derived from the sensor in a position-dependent manner. AV sensors can be used as limit switches operated with a single large vane. Other possible applications: as tachometer sensors in conjunction with gears or as synchronization elements together with drivers or sectors.

- P-switching power output - Accurate monitoring of the differential to predict the pulse width - Operated by a low-cost ferromagnetic vane that is easy to manufacture - Magnet and sensor in the same rugged housing - Sealed design ... dust or dirt tight - Operating speed from 0 kHz to 100 kHz ... no minimum operating speed - On/off timings definable by vane size - Precise mechanical operating characteristics
