Product Overview
The MMCX-C-J1.5 is an MMCX female crimp-type connector specifically designed by our company for miniaturized RF applications. A standout product in our miniature connector lineup, it retains the convenient 360-degree rotating lock feature characteristic of the MMCX series while utilizing a precision crimp structure to provide a fast, reliable termination solution for small-diameter RF cables such as RG174 and RG316. Offering excellent vibration resistance and environmental durability, it represents a mature solution developed to meet the industry trends of miniaturization and high-density integration in modern communication equipment.
Working Principle
The MMCX-C-J1.5 utilizes a unique push-on coupling mechanism, achieving quick connection and 360-degree free rotation through a precisely engineered internal snap-fit structure. When mated with the corresponding plug, its internal elastic contacts form a stable, low-impedance electrical path with the plug's center pin. The crimp design uses specialized tools to permanently secure the connector's rear body to the cable's outer conductor (shield) and insulation layer. This ensures stable electrical connections and superior signal transmission performance even in harsh environments subject to vibration and shock.

Installation Guidelines
Cable Preparation: Strictly follow the dimension drawings provided by our company to strip the cable jacket, shield, and insulation, ensuring precise dimensions for each layer.
Crimping Tool: You must use our recommended specialized crimping tool to ensure crimp quality and the electrical performance of the connector.
Cleanliness Check: Before crimping, please check that the inside of the connector and the cable end face are clean and free of debris to ensure connection quality.
Crimping Force: Complete the crimping in a single stroke. Avoid repeated crimping to prevent deformation of the sleeve or damage to the cable.
Mating Operation: When connecting or disconnecting the MMCX plug, please grip the connector body. Never pull the cable directly to prevent damage to the crimp joint.
