The LYP series circular aviation plug housing is made of high-strength aluminum alloy material and is connected by a bayonet type outer groove. It has the advantages of small size, light weight, easy use, resistance to insertion and extraction, good sealing, corrosion resistance, good conductivity, and good pressure resistance. It can also be interchanged with the YP series and is an ideal replacement product for the old-fashioned "P" type connector. It is widely used for circuit connections between electrical equipment and various instruments and meters.
