Our sensors work on the two-wire current loop principal. The advantage is simplicity and robustness. Especially to overcome corrosive electrical connections.

Most sensors are manufactured with a 4,5metre cable as standard. Although this is too long for most applications, it ensures that connection plugs are well away from the hinge movement of a planter row-unit.
