The automobile industry has standardized power levels of 24 VDC or less. Reed Switches perform exceptionally well at such low loads and consequently have very high life. Molded and encapsulated reed sensors are specially manufactured to withstand shock and extremes of temperature and humidity. A few automobile applications are listed below. We have also suggested few of our products for use in each application, but this does not mean that the other products in the same product category will be unsuitable.
