4PDT Electromagnetic Relay
Electromagnetic relay is a kind of electromechanical component which uses the input signal to generate electromagnetic force in the core of electromagnet and attract the armature, so that the contact action can be opened, closed or converted control. ATO, as the relay source distributor, provides high quality 4PDT electromagnetic relay. 14-pin electromagnetic relay adopts insulated transparent shell, operate temperature between -25 ℃ and 55 ℃. 12V, 24V, 110V, 220V coil voltages are available. 4 pole double throw electromagnetic relay is widely used in remote control device, electronic equipment, audio equipment and automation system. ATO as a maker will also provide quality customized service.
Features:
- High reliability. The 4 pole double throw electromagnetic relay has no mechanical parts, and the contact function is completed by solid devices. Because there are no moving parts, it can work in the environment of high impact and vibration.
- High sensitivity, good electromagnetic compatibility. The electromagnetic relay has a wide input voltage range, low drive power, and can be compatible with most logic without the need for buffers or drivers.
- Capable of fast conversion. Electromagnetic relays use solid state devices, so the switching speed can be from a few milliseconds to a few microseconds.
- Low electromagnetic interference. The electromagnetic relay does not touch the ignition arc, thus reducing the electromagnetic interference. Similarly, 3PDT electromagnetic relay also have low electromagnetic interference.

ATO-EMR-HH54P
When a certain voltage or current is added to both ends of the coil of the 4PDT electromagnetic relay, the magnetic flux generated by the coil passes through the magnetic circuit composed of the core, noir iron, armature iron and the working air gap of the magnetic circuit. Under the action of the magnetic field, the armature attracts to the pole surface of the core, thus pushing the normally closed contact of the contact to break and the normally open contact to close. When the voltage or current at both ends of the coil is less than a certain value, the mechanical reaction force is greater than the electromagnetic suction, the armature returns to its initial state, the normally open contact is disconnected, and the normally closed contact is connected.
