The **M2REB-R53-M2/N** is a specialized high-density electrical connector, typically part of the **M2 series** manufactured by Hirose Electric or similar precision component vendors. These are widely used in telecommunications, medical equipment, and high-reliability industrial computing. ### 1. Technical Specifications Overview This component is a multi-contact, rectangular interface connector designed for board-to-cable or rack-and-panel applications. | Feature | Specification | | :--- | :--- | | **Series** | M2 Series (High-Density Rectangular) | | **Number of Pins** | 53 Pins | | **Mounting Type** | Through-hole / Panel Mount | | **Termination Style** | Solder or Crimp (model dependent) | | **Contact Plating** | Gold (typically for high-reliability signal integrity) | | **Gender** | Receptacle (Female) | --- ### 2. Key Electronic Characteristics The "Electronic Parts" composition of this connector involves materials and design choices that ensure signal stability: * **Contact Resistance:** Engineered to maintain low resistance (usually $<30m\Omega$) to prevent voltage drops across the 53 pins. * **Dielectric Withstanding Voltage:** The internal insulation (often glass-reinforced PBT or similar resin) is rated to prevent arcing between closely packed pins at high voltages (typically $500V$ to $1000V$ AC). * **Insulation Resistance:** High-grade plastics ensure that there is no leakage current between the high-density pins, maintaining a resistance of $>1000M\Omega$. * **Current Rating:** Designed for signal-level currents, usually ranging from $1A$ to $3A$ per contact. --- ### 3. Structural Components The "M2/N" designation often refers to specific hardware or shell configurations: 1. **Insulator Body:** The core holding the 53 contacts in a precise grid to prevent misalignment during mating. 2. **Metallic Shell/Shielding:** The outer casing provides EMI (Electromagnetic Interference) protection, which is critical for high-frequency signal transmission. 3. **Locking Mechanism:** The "REB" and "M2" portions of the code often signify the type of screw-lock or latching mechanism used to secure the connection against vibration. --- ### 4. Common Applications Due to its high pin count and robust build, you will find this part in: * **Industrial PLC Units:** For multiple sensor inputs. * **Medical Diagnostic Imaging:** Handling high-density data streams. * **Avionics Control Systems:** Where space is limited but reliability is non-negotiable.
