Sensors: Quitting the Quicksilver



Nonmercury RoHs-compliant switches can be actuated by ferrous metal

Magnasphere Corp., is finding uses for its non mercury, RoHS-compliant tilt switches in a variety of off-highway applications to sense outrigger, boom or hitch positions. The unidirectional model pictured here, as well as an omnidirectional model, require no standby power consumption, feature precision switching ranges and are chemically inert. One of the unique capabilities of the Magnasphere switch technology is that it can be actuated by ferrous metal. The switch can act as a stand-alone ferrous proximity sensor with no magnet actuator required. Because the spherical contact is a magnet, the switch can be actuated by the presence of ferrous metal, so an external magnet is not required.
