FQ18 Series 12 Pin Circular Connector Flange Female Socket With Wire Spring Tail

Product Specification

FQ Series 12 Pin Waterproof Circular Connector Socket – Shell Size 18

Product Description

The FQ Series 12 Pin Waterproof Circular Connector Socket is designed to provide stable and secure electrical connections for industrial equipment operating in demanding environments. Manufactured in accordance with the DZ4Q/RE008-84 standard, the FQ series is an enhanced version of the traditional Q series, offering improved waterproof performance, compact construction, and dependable long-term reliability.

This 12-pin socket is ideal for applications requiring multiple signal connections in a compact installation space. The connector adopts an advanced squirrel-cage elastic contact structure, which delivers more consistent contact pressure than conventional wire spring designs. This innovative structure helps reduce contact resistance, improves conductivity, and maintains reliable electrical performance even under vibration, mechanical shock, and frequent connection cycles.

Combined with a lightweight anodized aluminum alloy shell and a secure bayonet locking mechanism, the FQ connector offers excellent durability, corrosion resistance, and sealing performance. Its IP67 protection rating makes it suitable for applications exposed to moisture, dust, and other challenging environmental conditions.
