The **27P-R** generally refers to a specific series of high-density, wire-to-board or board-to-board connectors, often associated with the **JST (Japan Solderless Terminal)** PUD series or similar compact electronic interconnect systems. Below is a breakdown of the technical specifications, physical characteristics, and applications for this type of electronic component. --- ### 1. Technical Specifications These parts are designed for reliability in space-constrained environments. | Feature | Typical Specification | | :--- | :--- | | **Pin Count** | 27 Pins (Positions) | | **Pitch** | 2.0 mm (standard for the series) | | **Current Rating** | 3A AC/DC (approx.) | | **Voltage Rating** | 250V AC/DC | | **Mounting Type** | Right Angle (indicated by the "-R") | | **Configuration** | Double Row | --- ### 2. Key Components of the Part Electronic connectors like the 27P-R consist of three primary elements: 1. **Housing (The "Body"):** Usually made of high-temperature thermoplastic (e.g., Nylon 66 or PBT). It holds the pins in place and provides the locking mechanism. 2. **Contacts (The "Pins"):** Copper alloy base with tin or gold plating to ensure high conductivity and prevent oxidation. 3. **Solder Leads:** The "R" suffix specifically denotes a **Right-Angle** orientation, meaning the connector sits flat on the PCB and the mating cable enters parallel to the board. --- ### 3. Usage and Applications These connectors are found in modern electronics where multiple signals must be transmitted through a single compact interface. * **Consumer Electronics:** Internal wiring for LED TVs, printers, and gaming consoles. * **Industrial Automation:** Connecting sensors or control panels to a main logic board. * **Automotive Systems:** Low-current signal routing for dashboard displays or infotainment systems. * **Medical Devices:** Reliable signal transmission for diagnostic equipment. --- ### 4. Part Number Breakdown (Typical) While naming conventions vary by manufacturer, they usually follow this logic: * **27:** The number of circuits or "poles." * **P:** Denotes a "Plug" or "Pin" header. * **R:** Denotes "Right Angle" orientation (Side Entry). ---
