The **M2PHSL-152-R** is a specific type of high-density interconnect component, typically classified as a **Pin Header or Board-to-Board Connector**. These are essential electronic parts used to bridge electrical signals between two Printed Circuit Boards (PCBs) or between a cable and a board. --- ### 1. Technical Specifications The part number follows a modular naming convention used by manufacturers (often associated with brands like **METZ CONNECT** or similar high-precision connector firms). | Feature | Specification | | :--- | :--- | | **Component Type** | Male Pin Header | | **Pitch** | 2.00 mm (typically) | | **Number of Pins** | 152 Pins | | **Configuration** | Dual Row (usually 2 x 76) | | **Mounting Type** | Through-Hole (THT) or SMT (Surface Mount) | | **Orientation** | Straight (Vertical) | | **Plating** | Selective Gold or Tin (R often denotes RoHS Compliance) | --- ### 2. Physical Construction The "electronic parts" of this connector consist of three primary elements: 1. **The Pins (Contacts):** Usually made of a copper alloy (like phosphor bronze). These provide the electrical conductivity. The "152" in the part number indicates a high-density configuration, common in computing or industrial control systems. 2. **The Insulator (Housing):** A high-temperature thermoplastic (such as LCP or PBT). This keeps the pins electrically isolated from one another and provides mechanical stability during soldering. 3. **Plating:** To prevent oxidation and ensure low contact resistance, the pins are coated. Gold plating is often used on the contact point, while tin is used on the solder tails. --- ### 3. Application & Usage Because of the high pin count (152), this part is typically used in complex electronic assemblies: * **Daughterboard to Motherboard:** Connecting specialized processing cards to a main system board. * **Industrial Automation:** High-speed data and signal transmission in PLC units. * **Testing Equipment:** Used in "Bed of Nails" testers or diagnostic interfaces where many signals must be tapped simultaneously. --- ### 4. Part Number Breakdown (Typical) While naming conventions vary by brand, the code generally breaks down as follows: | Code Segment | Meaning | | :--- | :--- | | **M2** | Metric Series (2.0mm Pitch) | | **PH** | Pin Header | | **SL** | Slimline or Specific Low-profile housing | | **152** | Total Number of Positions | | **R** | RoHS Compliant (Lead-free) |
