FQ series connectors

FQ14 black connector FQ14 grey connector FQ14 connector FQ18 connector

 

   FQ series of waterproof circular electric connectors accord with the standard DZ4Q/RE008-84, which is certificated by Ministry of the electronics industry administrative bureau office. The product has advanced structure, high dependability, small volume, light weight, excellent waterproof and the bayonets are connected quickly. The pins and the down-lead of jacks are welded. These characters make it easy to operate and reduce the cost. They are widely used in various kinds of electric equipments. Also you can change the pin and jack to match your requirement.
