We are involved in system and detail design down to cabinet level, as well as installation planning and set to work.
Inductive proximity switches have been developed for contactless position sensing under water. The inductive proximity switch consists of a sensor element which is mounted in a plastic housing. A cable specially designed for underwater use is connected to the sensor element. The housing is then molded so that the sensor element and the cable connection are fully surrounded by the molding compound. This ensures that no water will enter the sensor element or the connection area even if the housing should be damaged.

The sensor element works with interaction between an induced magnetic field and the magnetic field created by eddy currents in the target. The sensing distance is almost the same for all metals. As a standard the proximity switches are delivered with a 2 m cable, but other cable length can be offered on request.
The proximity switch could be configured to suit various applications upon request. Please contact us for more details.
