Product Description

High-Vibration Resistant Threaded Circular Connector

Designed for applications exposed to strong mechanical stress, this connector offers excellent vibration and shock resistance. It withstands 60g sine vibration with temperature cycling simulation for 36 hours, random vibration up to 49.5g RMS at ambient temperature, and 300g half-sine shock. The triple-start threaded coupling with anti-loosening structure ensures stable mating under continuous vibration, making it suitable for mobile equipment, airborne systems, and rugged electronic platforms.
