For the hydraulic lifting system of a tractor with a current of 20A, what connector should be selected?

A: Select the WS series aviation connector (6Pin, rated current 20A). It adopts multi-strand copper wire cores (strong current-carrying capacity), is oil-resistant (complying with ISO 6743-4 standard, suitable for hydraulic oil), and impact-resistant (30g, impact during tractor traction). At the same time, IP67 protection can prevent field mud and water, and the contact resistance is <5mΩ, avoiding weak lifting of the hydraulic system caused by current fluctuations.
