Standex Electronics Hall Effect Sensors offer solid state reliability, low power consumption, and consistent activation points over a wide temperature range in a rugged and environmentally isolated package. The hall effect sensor is a semiconductor device which is made using an integration process. An electric current must be flowing into the device in order to carry out its function. With current flowing, the hall sensor will interact with the presence of a magnet field producing a voltage. This voltage level, measured in milli-volts, is proportional to the relative strength of the magnetic field. The new range of Hall Effect Sensor products are available with a variety of custom options, including various outputs (switch, latch), high temperature options, as well as custom package designs. Additionally, Standex Electronics specializes in customizing designs to specific customer needs "CUSTOM IS STANDARD".
