The part number **10PA-1C0-R** typically refers to a specific series of **Wire-to-Board Connectors** or **Pin Headers**, often associated with manufacturers like JST or similar electronic component suppliers. Specifically, this part is part of the **PA Series** (2.0mm pitch). --- ## Technical Specifications The following table outlines the primary electrical and physical characteristics of the 10PA-1C0-R component: | Feature | Specification | | :--- | :--- | | **Component Type** | Retainer / Housing Accessory | | **Series** | PA Series (Secure Locking) | | **Pitch** | 2.0 mm (0.079 inches) | | **Number of Circuits** | 10 Positions | | **Material** | Nylon 66, UL94V-0 Rated | | **Color** | Natural (White/Ivory) | | **Mounting Type** | Component for crimp housing | --- ## Key Features & Functions ### 1. The "Retainer" Role The **-R** suffix usually indicates a **Retainer**. In electronic connector assemblies, a retainer serves two main purposes: * **Secondary Lock:** It ensures that the crimped contacts are fully seated in the housing and prevents them from backing out under vibration. * **Reliability:** It increases the contact retention force, making it suitable for high-vibration environments like automotive or industrial machinery. ### 2. Physical Design * **Compact Pitch:** The 2.0mm pitch allows for high-density wiring on a Printed Circuit Board (PCB). * **Polarization:** The design is typically polarized to prevent incorrect insertion into the mating header. ### 3. Application Use Cases * **Home Appliances:** Refrigerators, washing machines, and air conditioners. * **Industrial Automation:** Sensor connections and PLC modules. * **Office Equipment:** Printers and scanners where secure signal transmission is critical. --- ## Part Number Breakdown Understanding the nomenclature helps in identifying similar parts: | Segment | Meaning | | :--- | :--- | | **10** | Number of circuits/pins (10 pins) | | **PA** | Series name (JST PA Series) | | **1C0** | Internal manufacturer configuration/revision code | | **R** | Denotes a **Retainer** | --- ## Compatible Components To use the 10PA-1C0-R, you generally require the mating components within the same series: 1. **Housing:** The plastic shell that holds the crimp terminals. 2. **Contacts:** Crimp terminals (e.g., SPH-001T-P0.5L). 3. **Header:** The male pin assembly mounted on the PCB.
