The coil of the non-polar relay has no direction, and it can be connected at will to make the relay node move. The coil of the polarized relay has a direction and cannot be connected casually. There is a magnet in the coil of the polarized relay for power assistance, so the driving energy is relatively small. Panasonic's polarized relays can generally be driven by 200mW, and ordinary non-polarity relays generally need more than 500mW.
Polarized relay (polarized relay) DC pole relay. Referred to as a pole relay. This relay has the function of reflecting the direction of the external input signal electrodes (positive and negative).
main feature:
①In the magnetic circuit structure of China electrical relay the relay, there are permanent magnets or local coils that function as permanent magnets.
②The action of the relay armature is controlled by two independent magnetic systems: one is controlled by the electromagnetic system generated by the input coil current, and the magnetic flux generated by it is called the control magnetic flux φk; the other is controlled by the permanent magnet system generated by the permanent magnet, The magnetic flux formed by it is called polarization flux φj.
③High sensitivity, the pole relay can operate with less ampere-turn value. For example, some action ampere turns are 1 to 4, while the electrodeless relay generally needs 50 to 200 ampere turns.
④ The action time is fast, the fastest pole relay only needs 1~2ms, or even less. The stepless relay needs 10~100ms, and the action time of some large relays is slower.
the difference:
The coil of the non-polar relay has no direction, and it can be connected at will to make the relay node move.
The coil of the polarized relay has a direction and cannot be connected casually.
There is a magnet in the coil of the polarized relay for power assistance, so the driving energy is relatively small.
Ordinary non-polar relays generally need more than 500mW.
