Which connector should be selected for the grain flow sensor of a combine harvester?

Q1: Which connector should be selected for the grain flow sensor of a combine harvester?

A1: The M12 series (IP67) is recommended. 3 pins can transmit flow signals (accuracy ±0.1kg/s). The shell material is PA66 + glass fiber (impact-resistant, capable of withstanding grain impact), and the contacts are nickel-plated (resistant to grain dust and pesticide corrosion). It is suitable for the vibration (15g) and dusty environment of the harvester, with a plug-in life of ≥5000 times, facilitating maintenance during the annual idle period.
