Capacitor type proximity switch or inductive type proximity switch.Automatic electric control unit includes the resistance R2 and three of parallel connection
Pole pipe K1, the normality of K1 is by the state of resistance R2 short circuit.Automatic electric control unit and electromagnetic lock coil
TC connects, microswitch M1 and the coils connected in series of audion K1.
In the case of 12V power subsystem disconnects, Electromagnetic lock T1 is in the position not worked.
When after 12V power on, the circuit of electromagnetic lock coil TC is connected, and now resistance R1 by K1
Short circuit, electromagnetic lock coil TC is attached directly to power supply, has the first electric current, and Electromagnetic lock moves to work
Position, electromagnetic lock T1 is in the lock state, and now, microswitch M1 is touched, and electricity i.e. detected
Location when magnetic padlock body T1 is in work, in response to this, the normally-closed contact of relay K 1 disconnects,
Resistance R2 is linked in the loop of electromagnetic lock T1 coil, and in loop, resistance becomes big, by electromagnetism locking wire
The electric current of circle place circuit is less than the first electric current from the first current switching to the second electric current, the second electric current.
At this moment, the electric current flowing through electromagnetic lock T1 coil diminishes, and solves electromagnetic lock coil TC and self can send out
The problem that heat is the biggest, improves the reliability of electromagnetic lock.
Embodiments of the invention are described, it should be noted that above-described embodiment is only used above with reference to accompanying drawing
In explanation, not exhaustive, those skilled in the art can inspire in invention thought of the present utility model
Under, carry out the replacement of some parts, change and change.
