Magnetic Proximity Switch Circuit


Posted on Feb 5, 2014

Welcome to the weblog where we discuss about electronic circuits schematics, PCB design, diy kits and electronic projects diagrams. Here is the circuit diagram of a magnetic proximity switch that finds a lot of applications in abounding fields. The ambit is based on a alluring reed switch(S1) as the adjacency sensor. A monostable multivibrator bas

ed on NE555 (IC1) and a toggle cast bomb based on CD4013 (IC2) does the blow of the circuit. When a allurement is accomplished in adjacency of S1 it closes to accord a abrogating activate at pin 2 of IC1. The achievement of IC1 goes top for a time determines by R2 and C2. This clocks the IC2 active as a toggle cast flop. The achievement (pin 1 ) of IC2 goes top and the transistor Q1 is biased to ON. The broadcast is activated and so do the accessories affiliated to the relay. The LED D1 glows if IC1 is triggered.
