Level of protection: IP65; gear module: 2~6; output waveform: approximate sine wave; frequency range: 20 ~ 10,000 Hz; coil resistance: 1100 ±100 Ω. Working environment temperature: -25°C to 85°C; white PET or nylon wire sleeve temperature: -40°C to 150°C. 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 polarity, one end connected to the signal output, the other end grounded, connections can be made interchangeably. Installation method: The sensor is installed on the flywheel housing and positioned perpendicular to the upper surface of the flywheel tooth. The sensing end surface is 1mm from the top of the flywheel tooth. The smaller the distance, the higher the output signal induced.
