YD series circular rain proof connectors are used extensively in line connections between electrical equipment, various instruments and meters. It meet GB5226, They have the features of small volume, light weight, convenient application, high durability of plugging and unplugging, Square threaded coupling. IP54 protection. It is the ideal product of a new generation to replace the old P series connectors.
Characteristics
1. The dimesions of YD is same as P series.
2. More safety: Have a earth pin, When the plug connect with the receptacle, the earth pin with connect first then others. When they dismiss, the earth pin will dismiss later;
3. Rain proof, IP54;
4. Dust cap of plug and receptacle, protact the connector;
5. The metal shell is connecting with the earth pin;
6. Back shell can connect with cable or metal tube.
