The **M2MST-C-R** is a specific electronic component, typically identified as a **high-density, multi-row connector header** (often associated with the M2M series from manufacturers like Harwin or similar high-reliability interconnect brands). These components are designed for high-vibration environments and compact PCB (Printed Circuit Board) layouts. --- ### 1. Technical Specifications The following table summarizes the primary electrical and physical characteristics of this part series: | Feature | Specification | | :--- | :--- | | **Type** | Male Header / Surface Mount (SMT) | | **Pitch** | 2.00mm (0.0787") | | **Rows** | Dual Row (Standard) | | **Contact Material** | Phosphor Bronze or Copper Alloy | | **Plating** | Gold (Contact area) / Tin (Termination) | | **Current Rating** | 2.0A to 3.0A per contact (approx.) | | **Voltage Rating** | 250V AC/DC | --- ### 2. Key Design Elements #### A. Surface Mount Technology (SMT) The "-C-R" suffix often indicates the packaging and mounting style. * **Mounting:** It is designed for automated pick-and-place assembly. * **Mechanical Hold:** Often includes "shrouded" or "latched" designs to prevent accidental disconnection. #### B. High Reliability Unlike standard commercial headers, M2M series connectors are built to withstand: * **Vibration:** Tested to maintain electrical continuity under mechanical stress. * **Operating Temperature:** Typically rated from **-55°C to +125°C**, making them suitable for industrial and aerospace applications. --- ### 3. Application Use Cases The M2MST-C-R is frequently found in the following systems: 1. **Industrial Controls:** Connecting sensor modules to main processing boards. 2. **Medical Imaging:** High-density signal routing in portable diagnostic equipment. 3. **Aerospace/Defense:** Internal board-to-board connections where weight and space are restricted. 4. **Embedded Computing:** Connecting daughter cards to motherboards. --- ### 4.
