II. Product Features
90° Right Angle 4-Pin Structure for Miniaturized Layout
Adopting a 90° right angle design with horizontally extended pins, the four positioning solder legs fit tightly to the PCB, providing strong mechanical stability after installation and effective resistance to external impact. It is ideal for RF interface layout in slim and miniaturized electronic devices. The four-corner positioning design enables accurate installation, compatible with wave soldering and reflow soldering, ensuring high welding efficiency and consistency.
Snap-On Latching for Efficient & Stable Signal Transmission
Using a snap-on latching coupling mechanism, it allows fast and convenient connection and disassembly with uniform locking force. It features strong anti-vibration and anti-shock performance, maintaining stable connection and avoiding signal interruption in automotive, handheld devices and other vibrating environments. The inner conductor is made of high-purity gold-plated brass with contact resistance below 5mΩ, reducing signal loss and ensuring efficient RF transmission with minimal reflection and interference. Built-in PTFE dielectric provides stable dielectric constant, effectively suppressing crosstalk and improving communication quality.
Multi-Specification Adaptation for Diverse Scenarios
With a standard impedance of 50Ω and frequency range from DC to 6GHz, it meets the requirements of Bluetooth, Wi-Fi, GPS, 4G and other communication bands. Suitable for PCBs with thickness ranging from 0.8mm to 2.0mm, the four-pin spacing complies with industry standards and can directly match pre-drilled PCB vias without additional board modification, enabling convenient and efficient installation. It supports single-port design for single-antenna communication equipment, and multi-port combinations can be customized upon request.
High-Strength Materials for Complex Working Conditions
The housing is made of high-strength nickel-plated brass with excellent corrosion and oxidation resistance, capable of withstanding a wide temperature range of -40℃ to 125℃, adapting to harsh environments including high temperature, low temperature and humidity. Tin-plated pins ensure excellent solderability and firm joints, with no deformation or desoldering after welding, extending product service life.
III. Product Advantages
Excellent RF Performance with High Consistency
An automated RF testing system performs full inspection of key indicators such as insertion loss, VSWR and isolation for each batch. Insertion loss ≤ 0.1dB, VSWR ≤ 1.3, ensuring stable and consistent RF performance. The MES system monitors processing accuracy, assembly clearance and other parameters in real time, controlling dimensional tolerance within ±0.02mm to guarantee precise matching with antennas and equipment.
Balanced Standardization and Customization
Interface specifications and mounting dimensions comply with international standards and are compatible with mainstream PCB design software libraries. Customers can use the products directly without redesign, reducing selection and adaptation costs. Customization response is fast: standard samples are delivered in 2 working days, with controllable mass production cycles to quickly meet personalized needs such as pin length and mounting adjustments.
High Durability & Long Service Life
Products pass multiple reliability tests including mating cycle, salt spray and temperature cycling. Mating life exceeds 5000 cycles, salt spray resistance reaches 48 hours, ensuring long-term stable operation in harsh environments and extending equipment service life.
Eco-Friendly & Globally Compliant
All materials meet RoHS, REACH and other international environmental standards, free of hazardous substances such as lead and mercury. They comply with environmental regulations worldwide, helping customers’ products enter global markets smoothly.

V. FAQ
Q1: What key parameters need to be confirmed for selection?
A1: Four core points: ① Interface type (MCX female) and impedance (50Ω) to match antennas and equipment; ② Frequency range for the target communication band; ③ Mounting style (90° right angle 4-pin) plus PCB thickness and mounting hole size; ④ Application environment (temperature, vibration, humidity). Our technicians provide a tailored selection proposal within 1 hour.
Q2: How to resolve unstable signal during use?
A2: First check whether the connection is securely locked without looseness. Then inspect solder joints for firmness, cold soldering or desoldering. If caused by environmental factors, replace with a higher-protection connector or add a protective housing.
Q3: Is waterproof customization supported?
A3: Waterproof customization is available. By adding waterproof gaskets and optimizing sealing structures, protection grades from IP65 to IP67 can be achieved, suitable for outdoor, automotive and other humid environments. Specific waterproof grade and application scenario requirements are required.
