Battery contactors for industrial trucks

AFS Series contactors are designed for use with electric vehicles in material handling. They are mainly used as motor contactors and much demanded as replacement and new contactors for most leading brands of trucks.

The latching DC NO contactors do not consume any energy to maintain a closed-circuit position for a long period of time, which makes them ideally suited for deep discharge protection of batteries. In addition to that, they allow for saving a lot of energy compared with other common commercial NO contactors.
