FQ24 Series 19 Pin Circular Connector Straight Wire Spring Female Plug FQ24-19TK

Product Specification

FQ Series 19 Pin Waterproof Circular Connector Plug – Shell Size 24

Product Description

The FQ Series 19 Pin Waterproof Circular Connector Plug is designed to provide reliable multi-pin electrical connections for industrial equipment operating in harsh environments. Produced in accordance with the DZ4Q/RE008-84 standard, this connector is an upgraded version of the conventional Q series, offering enhanced waterproof performance, improved structural stability, and dependable long-term operation.

Featuring a compact shell size and a 19-pin configuration, this connector is ideal for applications requiring stable signal transmission within limited installation space. The female contacts adopt an advanced squirrel-cage elastic contact structure, replacing the traditional wire spring design to provide lower contact resistance, stronger vibration resistance, and more consistent electrical performance. Together with the bayonet locking mechanism, the connector allows fast installation while maintaining a secure mechanical connection.

The anodized aluminum alloy shell provides excellent corrosion resistance and mechanical strength, while the IP67 sealing design effectively protects the internal contacts from water, dust, and other environmental contaminants. These features make the FQ series a dependable choice for demanding industrial electrical systems.
