The **SVB-0B-R/K** is a specific electronic component, typically categorized as a **Circular Push-Pull Connector** (often associated with the Lemo B-Series style or compatible high-precision interconnects). These parts are designed for high-reliability applications where space is limited and secure connections are critical. --- ## 1. Technical Specifications Below are the primary electronic and physical characteristics of the SVB-0B-R/K series: | Feature | Specification | | :--- | :--- | | **Series** | 0B (Small form factor) | | **Shell Style** | Fixed receptacle (usually back-panel mount) | | **Locking Mechanism** | Push-Pull self-latching | | **Contact Type** | Solder or Print (PCB) | | **Shielding** | 360° EMC screening | | **Operating Temp** | -55°C to +250°C (depending on insulator) | | **IP Rating** | IP50 (Indoor/Non-sealed) | --- ## 2. Key Electronic Components & Materials ### A. The Insulator The internal core is usually made of **PEEK (Polyetheretherketone)**. * **Electronic Property:** High dielectric strength and low outgassing. * **Purpose:** It prevents electrical arcing between the densely packed pins. ### B. Contacts (Pins/Sockets) The conductive elements are the most critical electronic part of the assembly: * **Base Material:** Copper alloy (Bronze or Brass). * **Plating:** Typically **Gold (Au) over Nickel (Ni)**. * **Function:** Gold plating ensures low contact resistance and prevents oxidation over thousands of mating cycles. ### C. Grounding & Shielding The outer shell is usually **Chrome-plated Brass**. * **EMC Performance:** The "K" or "R" variants often denote specific keying or grounding washers that ensure the shell is bonded to the chassis. This provides a path for EMI (Electromagnetic Interference) to drain to the ground. --- ## 3. Part Number Breakdown (Typical) While naming conventions vary slightly by manufacturer (e.g., Lemo, ODU, or Hirose clones), the code generally breaks down as follows: 1. **SVB:** Refers to the specific shell style (Fixed socket, nut fixing, often with a back-panel mount profile). 2. **0B:** The shell size. "0" is one of the smallest standard sizes, used for compact handheld devices. 3. **R/K:** These letters usually indicate the **Keying System**. * **Alpha-keys:** Ensure that a plug can only be inserted in one orientation to prevent cross-wiring. * **R:** Often signifies a specific angular alignment (e.g., two keys at 145°). * **K:** Often signifies a standard single-key or a specific G-key variant. --- ## 4. Common Applications Due to its high-density electronic design, the SVB-0B-R/K is found in: * **Medical Electronics:** Patient monitoring sensors and imaging equipment. * **Test & Measurement:** Data acquisition systems (DAQ) where signal integrity is paramount. * **Audio/Video:** Professional microphones and high-end camera power links.
