## Overview of the MA24FCA-R The **MA24FCA-R** is a specialized high-speed, high-density connector, typically part of a floating board-to-board connector system. These components are designed to facilitate secure electrical connections between two Printed Circuit Boards (PCBs) while compensating for alignment errors during assembly. --- ### 1. Key Technical Specifications The following table outlines the primary electrical and mechanical characteristics of the MA24 series: | Parameter | Specification | | :--- | :--- | | **Connector Type** | Board-to-Board (Floating Type) | | **Pitch** | 0.4 mm or 0.5 mm (Series dependent) | | **Contact Material** | Copper Alloy | | **Plating** | Gold (Au) over Nickel (Ni) | | **Current Rating** | 0.5A per contact | | **Voltage Rating** | 50V AC/DC | | **Operating Temp** | -55°C to +105°C | --- ### 2. Functional Electronic Features #### A. Floating Mechanism The "F" in the part number often denotes the **Floating** capability. This means the internal contacts can move slightly in the X and Y directions (typically ±0.4mm to ±0.6mm). * **Benefit:** Absorbs mounting misalignments and reduces stress on solder joints caused by vibration or thermal expansion. #### B. High-Speed Transmission The internal geometry of the pins is optimized for signal integrity. These connectors are commonly rated for high-speed protocols such as: * PCIe Gen 3/4 * MIPI (Mobile Industry Processor Interface) * SATA / USB 3.0 compatible speeds. #### C. Shielding and Grounding The MA24FCA-R usually includes integrated metal shells or grounding plates to minimize **EMI (Electromagnetic Interference)** and **Crosstalk**, which is critical for dense electronic environments like automotive infotainment or telecommunications. --- ### 3. Typical Applications Because of its robust floating structure and small footprint, the MA24FCA-R is used in: 1. **Automotive Electronics:** Navigation systems, ADAS sensors, and head units where vibration resistance is mandatory. 2. **Industrial Automation:** PLCs and robotic controllers. 3. **Consumer Electronics:** High-end laptops or cameras where internal boards are stacked. --- ### 4. Mounting & Physical Configuration * **SMT (Surface Mount Technology):** The part is designed for automated pick-and-place assembly with solder pads on the bottom. * **Polarization:** The housing is keyed to prevent incorrect insertion (reverse mating). * **Click-Feel:** Provides tactile feedback to the assembly operator ensuring the connection is fully seated.
