PROXIMITY SWITCH AND METHOD FOR ADJUSTING IT

摘要

PROBLEM TO BE SOLVED: To provide a proximity switch capable of setting an optimum receiving sensitivity at all times and detecting even when the shape and external dimension of an object to be detected diversely change. SOLUTION: A transmitting/receiving distance (x) between a transmitter 2 and a receiver 3 forming the proximity switch 1 for detecting the object to be detected by the change in a level of received magnetic flux signal is set so as to be relatively long when the length of one side of the object to be detected is long while setting so as to be relatively short when the length thereof is short.
