The **JB10CX26SN2-RK** is a specialized high-density circular connector, typically part of the **JB10 series** produced by manufacturers like JAE (Japan Aviation Electronics). These connectors are designed for compact electronic equipment requiring high reliability and space efficiency. --- ### 1. Part Number Breakdown While specific prefixes can vary by manufacturer, here is the standard technical breakdown for this series: | Component | Identifier | Description | | :--- | :--- | :--- | | **Series** | JB10 | Compact, high-density circular connector series. | | **Shell Size** | CX (or 10) | Refers to the outer diameter/housing size. | | **Contact Qty** | 26 | Contains 26 individual pins/circuits. | | **Gender** | S | Socket (Female contacts). | | **Orientation** | N | Normal keyway positioning. | | **Termination** | 2 | Often indicates a specific PCB tail length or solder type. | | **RoHS/Special** | RK | Compliance code (Lead-free/RoHS) or specialized kit packaging. | --- ### 2. Key Technical Specifications These parts are engineered for signal integrity in tight spaces. * **Contact Density:** 26 pins in a very small form factor. * **Coupling Mechanism:** Push-pull or threaded (depending on specific sub-series), designed for one-touch vibration-resistant mating. * **Contact Resistance:** Generally low (under 30mΩ) to ensure signal precision. * **Durability:** Rated for high mating cycles (typically 500+). * **Operating Temperature:** Usually rated from -55°C to +85°C. --- ### 3. Electronic Applications The **JB10CX26SN2-RK** is frequently used in the following environments: 1. **Handheld Devices:** Professional cameras, medical scanners, and portable testing equipment. 2. **Industrial Robotics:** Sensor arrays and control units where space is limited but high pin counts are needed. 3. **Aerospace/Defense:** Small-scale UAV (drone) control systems due to its lightweight and high-density nature. --- ### 4. Technical Drawing & Footprint * **Mounting Type:** This specific model is usually a **Receptacle** (S) intended for **PCB Mounting**. * **Pitch:** Because it packs 26 pins into a small shell, the pitch (distance between pins) is extremely fine, requiring precision soldering or automated SMT processes.
