DC24V / AC220V K23D-3 Pilot Operated Pneumatic Solenoid Coil 17.5mm x 50.5mm x 44mm
The structure and characteristics of the K23D-3 pilot operated solenoid valve coil, the bobbin body is composed of thermosetting resin, and a core coil winding and a terminal connection extending to one side of the bobbin provides the body of the bobbin. By providing a waterproof rib on the end face of thermosetting resin bobbin, the bobbin and package layer are well combined to form a sealing structure, thus fundamentally solving the problem of outer package layer and package of electromagnetic coil in injection molding. The problem with welding, even if there is condensed water on the surface of the coil, the condensed water cannot penetrate into the coil winding through the waterproof sealing structure rib in alternately heating and cooling the coil during use, so the coil maintains good water resistance and insulation performance.

How to increase Q value of solenoid valve coil?
The quality factor Q is a weight parameter reflecting the mass of the coil. Increasing the Q value of the coil is one of the important points to be paid attention to when winding the electromagnetic coil. So, how to improve the Q value of the electromagnetic coil? Let me elaborate as follows:
Choose the wire of the coil according to the working frequency. Inductors with short working and low frequency are usually fired with insulated wire such as enameled wire. The operating frequency is higher than tens of thousands of Hz. In circuits below 2MHz, multi-strand insulated wires are used to wind electromagnetic coils, which can effectively increase the surface area of the conductor and make the Q value higher than that of single-wire wound coils with the same cross-sectional area. About 30%.
Use high quality coil bobbins to reduce dielectric losses. In high frequency applications such as short wave, the dielectric loss is very high due to the winding of the ordinary coil. Therefore, high-frequency dielectric materials such as high-frequency ceramics, ptfe, and polystyrene should be used as the framework and wound by winding method.
Choose a reasonable coil size to minimize damage. When winding thickness T, winding length L and outer diameter D satisfy 3T + 2L = D, the loss is also minimal. Shielded coils are optimal when L/D = 0.8-1.2.
Choose a reasonable shield diameter. Using a guard increases the damage to the solenoid and reduces the Q value. Therefore, the shield size should not be too small. If the shielding area is too large, the volume will increase.
