Description
The MCX (Micro Coaxial) Female Crimp connector is an ultra-miniature RF interface designed for 50 Ohm systems where space is the primary constraint. This connector serves as the “jack” side of the connection, designed to mate seamlessly with any standard MCX male plug. This specific variant is precision-machined to fit RG178 (and similar 1.8mm OD) coaxial cables, making it one of the smallest high-reliability crimp solutions for internal RF routing.
The connector features a Gold-Plated Brass body and center contact to ensure maximum electrical conductivity and superior resistance to corrosion. Its snap-on coupling mechanism provides a secure, vibration-resistant connection and allows for 360-degree rotation after installation, which effectively eliminates mechanical torque on the thin RG178 cable. The assembly utilizes a precision crimp-on outer ferrule and a solder center pin, providing a mechanically robust termination that maintains electrical stability in mobile and handheld applications.
Key Technical Advantages
-
Ultra-Miniature Design: The compact MCX footprint enables high-density placement on congested circuit boards and within slim electronic housings where standard connectors are too large.
-
Snap-On Convenience: The tool-less mating interface facilitates rapid assembly and maintenance, while the rotating design prevents cable kinking during internal routing.
-
Gold-Plated Signal Integrity: Heavy gold plating on all critical contact surfaces ensures a low-resistance signal path and a high number of mating cycles without performance degradation.
-
Optimized for RG178: Specifically sized for the 1.8mm profile of RG178 cable, ensuring a perfect mechanical fit for the ferrule and preventing signal leakage at the termination.
-
Vibration Resistance: The combination of the snap-on lock and secure crimp termination makes it highly reliable for handheld equipment and drone telemetry systems.
