FQ14 Series 2-Pin Circular Flange Female Socket With Wire Spring Tail Attachment

Product Specification

• Product Information

  The FQ Series Waterproof Circular Connector is a high-performance bayonet connector designed for reliable power and signal transmission in harsh industrial environments. Manufactured in accordance with DZ4Q/RE008-84, the FQ series is an upgraded version of the traditional Q series, offering enhanced waterproof performance, improved contact reliability, and a compact lightweight design.

  Unlike conventional connectors that use wire spring contacts, the FQ series adopts a squirrel-cage elastic contact structure, which provides lower contact resistance, greater contact stability, and excellent resistance to vibration and mechanical impact. Combined with a secure bayonet locking mechanism and IP67 sealing protection, the connector delivers dependable electrical performance even in environments exposed to moisture, dust, and frequent vibration.
