The **M2PHSH-161-R** is a specific type of electronic hardware component, categorized as a **Pin Header**. It is widely used in PCB (Printed Circuit Board) assembly to create secure, pluggable connections between boards or between a board and a wire harness. --- ### 1. Component Overview The part number typically follows a standardized nomenclature used by manufacturers (often associated with brands like Adam Tech or similar connector specialists). | Feature | Specification | | :--- | :--- | | **Component Type** | Male Pin Header | | **Pitch** | 2.00 mm (0.079") | | **Number of Rows** | Single Row | | **Total Pins** | 16 Pins | | **Mounting Style** | Through-Hole (THT) | | **Orientation** | Straight / Vertical | | **Plating** | Selective Gold or Tin (Standard "R" usually denotes RoHS compliance) | --- ### 2. Breakdown of the Part Number While nomenclature varies slightly by manufacturer, the code generally breaks down as follows: * **M2P:** Denotes a 2.0mm Pitch series. * **H:** High-temperature plastic/insulator material. * **SH:** Single Row, High profile (or specific series designation). * **16:** The circuit count (16 positions/pins). * **1:** Straight orientation (Right-angle is often designated by '2'). * **R:** **RoHS Compliant**, meaning it is free from lead and other hazardous substances. --- ### 3. Key Technical Characteristics #### Electrical Specifications * **Current Rating:** Typically 2.0A per contact. * **Insulation Resistance:** 1000 MΩ Minimum. * **Dielectric Withstanding Voltage:** 500V AC/DC. * **Contact Resistance:** 20 mΩ Maximum. #### Mechanical & Material Properties * **Insulator Material:** Usually Nylon 6T or LCP (Liquid Crystal Polymer), capable of withstanding the heat of wave soldering. * **Contact Material:** Copper Alloy (Brass or Phosphor Bronze). * **Operating Temperature:** -40°C to +105°C. --- ### 4. Common Applications * **Microcontrollers:** Connecting an Arduino or ESP32 board to a breadboard or shield. * **LCD Displays:** Interfacing 16x2 character displays to a control board. * **Internal Wiring:** Acting as a jumper header for configuration settings (using a shunt). * **Modular Electronics:** Creating stackable PCB layers in industrial equipment.
