Level of protection: IP65; gear module: 2~6; output waveform: approximate sine wave; frequency range: 20 ~ 10,000 Hz, coil resistance: 1100 100 ; Working environment temperature: -25~85, white PET or nylon wire sleeve temperature: -40 ~ 150 Output signal amplitude: 3.5V at 500rpm. The amplitude of the signal is proportional to the rotation speed and inversely proportional to the gap between the iron core and the top of the tooth. Connection method: two-wire connection; wiring: terminal wiring, the wire has no direction, one end is connected to the signal output, the other end is grounded and can be connected at will. Method of Installation: The sensor is installed on the flywheel shell and is perpendicular to the upper surface of the flywheel tooth. The sensing end surface is L1mm from the top of the flywheel tooth. The smaller the distance, the higher the output signal. induced.
