Proximity switch circuit with TCA205A

Published:2012/9/19 1:58:00 Author:Ecco | Keyword: Proximity switch | From:SeekIC

It uses integrated circuit TCA205A to form an inductive proximity switch. If the inductance coil is properly designed, the switching distance can be up to 13mm, the temperature coefficient is 0.05 % . The size of the resistor Ra will determine the switching distance, the RH will determine the width of the switch hysteresis loops.
