The MCX Horizontal Edge Mount Jack Switching Connector from Chin Nan is a precision-engineered RF connectivity solution designed for high-density routing and intelligent path switching in advanced Printed Circuit Board (PCB) designs. Featuring a specialized horizontal edge-mount configuration, this MCX switching connector can be precisely soldered to the edge of the PCB. This design significantly conserves board space and minimizes the overall packaging profile, empowering engineers to achieve critical device miniaturization. Operating within a 50 Ω impedance system, it is the premier choice for automotive Telematics systems, communication base station monitoring modules, and high-end wireless measurement equipment.
The technical highlight of this RF connector lies in its precision automatic path switching capability. When an external test probe is not engaged, the system maintains internal loop communication (supporting frequencies from 0 to 3 GHz); upon insertion of a test plug, the mechanical switch automatically redirects to the external path, supporting wideband transmission up to 0 to 6 GHz. Engineered for optimal RF efficiency, it maintains a maximum Voltage Standing Wave Ratio (VSWR) of 1.5 at both 3 GHz and 6 GHz. Coupled with an ultra-low maximum insertion loss of just 0.1 dB at 1 GHz, it maximizes signal integrity during the switching process. Furthermore, backed by a robust power handling capacity of 125W, it satisfies the rigorous demands of professional industrial and telecommunication applications.
To ensure uncompromising durability and superior electrical conductivity, the connector body is precision-machined from high-quality brass, perfectly complemented by a center contact made of brass and highly resilient beryllium copper. The integration of premium PTFE insulation provides excellent dielectric stability, enabling the connector to operate flawlessly in extreme environmental temperatures ranging from -55°C to 155°C. Mechanically, this edge-mount switching jack delivers a proven lifespan of 500 mating cycles and features a center contact axial retention force of 2.2 lbs, ensuring a steadfast physical connection over extended periods of industrial use.
In terms of electrical safety and environmental resilience, this coaxial switching receptacle holds a continuous working voltage rating of 250 volts rms at sea level and a dielectric withstanding voltage of 500 volts rms at sea level. The initial insulation resistance is strictly rated at a minimum of 1000 Megohms (500 Megohms min. after conditioning). To prioritize low-loss conduction, the contact resistance is stringently capped at a maximum of 5.0 Milliohms for the center contact and 1.0 Milliohms for the outer contact. Fully compliant with rigorous military testing standards, it has successfully passed the MIL-STD-202 Method 204 Test Condition B for vibration and MIL-STD-202 Method 101 Test Condition B for salt spray, proving its unwavering reliability in harsh, vibrating, and corrosive environments.
