Our company, Wuxi Dongying Electronics Co., Ltd., will offer you the customized relay coils in electrical control system, including electric meters, electromagnetic relays, intermediate relays. Relay coil is the main part of relay. The coil and armature inserted in the coil form an electromagnet. While the magnetic field is produced by the electric current generated by coils, the armature does some mechanical movement, which drives the contact to switch on or off the circuit. Relay is a circuit control device. It is usually used in the automated circuit. As the electric current through relay coils is small and the electric current or voltage controlled by the contact is high, relay coil is an ’automatic switch’, which uses the small electric current to control the larger one. In this way, it is helpful to automatic adjustment, safety and protection and conversion circuits.

Material selection and specification：Structure material:PA46, PA66, PC and so on
Enameled Copper wire specification: Ф0.06-0.6mm
Enameled Copper wire brand: ELEKTRISOLA

We have 15-year experience to customize relay coils. We are confident of our ability to cater for you and produce relay coils of all kinds of shapes and specifications. We pay great attention to the quality of coils. We manufacture every relay coil completely according to ISO 9001：2015, ISO14001：2015 Certification and IATF16949：2016 Certification. You shouldn’t worry about our products’ quality. We can produce specific relay coils with the specified relay resistance and winding as you want.

This type of relay coil is double loop coil. It is applied in the electric meter manufactured by a Japanese company. It plays the role of opening and closing.

Manufacturing process:
We use CNC eight-axis winding equipment to produce copper enameled wires, whose diameter is only 0.17mm and 0.21mm. Lines are tight between each other, so the changes of the products’ resistance are very tiny. Besides, soldering by automatic welding machines has the benefits of high efficiency of production and stability of quality. Up to now, it has sold about 8 million pieces.

Specification: 32.70×13.88×13.30

Material:PA46 Skeleton, ELEKTRISOLA enameled copper wire

Coil resistance:
The first circuit: 11.4~12.6Ω
The second circuit: 11.4~12.6Ω

If you want to produce relay coil, you can send the sample to us. Our engineer designs the relay coil for you. According to the outer casing of relay coil or the drawing that you offer, we will design the shell and change your idea to engineering products. Also, we will calculate the cost and provide the quoted price.
