The water level sensor of a rice transplanter is often immersed in muddy water (depth 10cm). Which connector should be selected?

A: Select the SP series waterproof connector (8Pin) with IP68 protection rating. It adopts a metal shell + double O-rings, can withstand immersion in 1 meter of water (far exceeding the 10cm requirement), is resistant to muddy water corrosion (salt spray test ≥1000h), and 4 pins transmit water level signals (accuracy ±1cm). It is suitable for the paddy field operation scenario of the rice transplanter, with a plug-in life of ≥3000 times, meeting the annual 200-hour operation demand of agricultural machinery.
