FQ Series IP67 Waterproof Circular Connector Socket – 3 Pin Bayonet Connector

Product Description

The FQ Series Waterproof Circular Connector Socket is designed for dependable power and signal transmission in industrial applications where protection against moisture, dust, vibration, and harsh environmental conditions is essential. Manufactured in accordance with DZ4Q/RE008-84, the FQ series is an upgraded version of the traditional Q series, offering enhanced sealing performance, improved mechanical reliability, and a more compact structure.

One of its key advantages is the innovative squirrel-cage elastic contact design, which replaces conventional wire spring contacts. This advanced structure provides lower contact resistance, greater contact stability, and improved resistance to vibration and mechanical shock. Combined with a quick-lock bayonet coupling mechanism, the connector enables fast installation while maintaining a secure and reliable electrical connection. Its lightweight aluminum alloy housing and IP67 protection rating make it an excellent choice for demanding industrial environments.
