The **M2PHS2L-CA-R** is a specific part number typically associated with a **2.0mm pitch, dual-row, horizontal SMT (Surface Mount Technology) pin header**. These components are fundamental in board-to-board or wire-to-board interconnections. --- ### 1. Part Number Breakdown (Typical Industry Logic) While specific manufacturers may vary slightly, the nomenclature generally breaks down as follows: | Segment | Meaning | Description | | :--- | :--- | :--- | | **M2** | Series/Pitch | Often refers to 2.00mm pitch spacing. | | **PH** | Product Type | **P**in **H**eader. | | **S** | Mounting Type | **S**MT (Surface Mount Technology). | | **2L** | Configuration | **2** Rows; **L** denotes Right Angle (Horizontal) orientation. | | **CA** | Material/Plating | Often signifies Gold Flash or specific plastic (e.g., LCP/Nylon 6T). | | **R** | Packaging | **R**eel (Tape and Reel) for automated pick-and-place. | --- ### 2. Technical Specifications This component is designed to provide a reliable electrical path between two PCBs or a PCB and a ribbon cable. * **Pitch:** 2.00 mm (Distance between the center of one pin to the next). * **Orientation:** Right Angle / Horizontal (The pins run parallel to the PCB surface). * **Rows:** Dual Row (2xN pins). * **Material:** * **Insulator:** High-temperature thermoplastic (capable of withstanding reflow soldering temperatures, usually up to 260°C). * **Contact:** Copper Alloy (Brass or Phosphor Bronze). * **Plating:** Usually Gold or Tin over Nickel. --- ### 3. Application Use Cases The M2PHS2L-CA-R is commonly found in compact electronic devices where vertical space is limited. 1. **Consumer Electronics:** Inside laptops, tablets, and handheld gaming consoles for internal module connections. 2. **Industrial Controllers:** Used for daughterboard stacking or sensor interfacing. 3. **IoT Devices:** Connecting communication modules (like LoRa or Zigbee) to a main control board. 4. **LED Lighting:** Interconnecting LED strips or control driver boards. --- ### 4. Key Advantages * **Space Efficiency:** The 2.0mm pitch is significantly smaller than the standard 2.54mm (0.1") pitch, allowing for higher pin density. * **SMT Compatibility:** Designed for automated assembly lines, reducing labor costs compared to through-hole parts. * **Low Profile:** The horizontal orientation keeps the total height of the assembly low, ideal for slim enclosures.
