Inductive Type Contactless Sensing Apparatus of Opening and Closeing the Door for a Vehicle

摘要

PURPOSE: An inductive type contactless door opening sensing apparatus is provided to obtain linearity and to effectively sense a signal by using an excitation coil to minimize the distortion of a signal. CONSTITUTION: A coupler(50) is formed to be correspond with a substrate(30) formed on a vehicle when a door is opened. An excitation coil(10) is formed on the top of the substrate in a predetermined form. The excitation coil implements the functions of oscillation and reception for an inductance signal.
