The **M2AS1-4121-R** is a specific part number typically associated with high-frequency connectors or specialized telecommunications components, often manufactured by companies like **Telegärtner** or related RF component suppliers. It is most commonly identified as an **SMA-type connector** or a similar RF interface component. Below is a detailed breakdown of the electronic and physical characteristics of this part. --- ### 1. Technical Specifications The part is designed for precision signal transmission in radio frequency (RF) applications. | Feature | Description | | :--- | :--- | | **Component Type** | RF Connector / SMA Adaptor | | **Interface** | SMA (SubMiniature version A) | | **Gender** | Often Male/Plug (depending on specific suffix) | | **Impedance** | 50 Ohms (Standard for RF) | | **Frequency Range** | DC up to 18 GHz | | **Body Material** | Stainless Steel or Brass with Gold Plating | | **Dielectric** | PTFE (Teflon) | --- ### 2. Key Electronic Parts & Construction The "electronic" performance of the M2AS1-4121-R relies on its physical geometry and material science: * **Center Contact:** Usually made of Beryllium Copper with gold plating to ensure low contact resistance and high durability over many mating cycles. * **Insulator (Dielectric):** High-grade PTFE provides the necessary isolation between the center conductor and the outer shell while maintaining a constant 50-ohm impedance to prevent signal reflections. * **Outer Shell/Body:** Provides the ground connection and electromagnetic shielding (EMI) to prevent signal leakage. * **Coupling Nut:** A threaded mechanism (usually 1/4"-36 thread) that ensures a secure, vibration-resistant mechanical connection. --- ### 3. Applications Components like the M2AS1-4121-R are found in high-performance environments: 1. **Telecommunications:** Base stations and cellular infrastructure. 2. **Test & Measurement:** Oscilloscopes, signal generators, and spectrum analyzers. 3. **Aerospace:** Satellite communication systems due to its lightweight and high-frequency stability. 4. **Medical Equipment:** Specialized imaging and diagnostic tools requiring high-frequency signal integrity. --- ### 4. Part Number Breakdown (General Convention) While prefixes vary by manufacturer, the code usually follows this logic: * **M2AS:** Series designation (often indicating Miniature/SMA series). * **4121:** Specific configuration (mounting style, e.g., PCB mount, Bulkhead, or Right Angle). * **-R:** Often signifies **RoHS Compliance** (Restriction of Hazardous Substances).
