The part number **570-059N05GR** refers to a high-performance **Micro-D connector** (specifically from the Glenair 570 series). These connectors are designed for high-reliability applications where space and weight are at a premium, such as aerospace, defense, and medical electronics. --- ### ## Technical Specifications The following table outlines the primary electrical and physical characteristics of this component: | Feature | Specification | | :--- | :--- | | **Connector Type** | Micro-D (Rectangular) | | **Number of Contacts** | 9 Pins | | **Gender** | Receptacle (Socket) | | **Pitch** | 0.050" (1.27 mm) | | **Shell Material** | Aluminum Alloy | | **Plating** | Electroless Nickel | | **Termination Type** | Solder Cup / Pre-wired (Depending on suffix) | | **Current Rating** | 3 Amps | | **Dielectric Voltage** | 600 VAC (Sea Level) | --- ### ### Key Components and Construction 1. **TwistPin Contacts:** The core of the 570 series is the **TwistPin** contact system. Unlike standard stamped contacts, these utilize a spring-wire bundle that provides 7 points of electrical contact. This ensures a stable connection even under extreme vibration and shock. 2. **Insulator Material:** Usually constructed from Liquid Crystal Polymer (LCP) or Polyphenylene Sulfide (PPS), which offers excellent thermal resistance and high dielectric strength. 3. **EMI Shielding:** The aluminum shell (marked by the "N" for Nickel plating) provides excellent Electromagnetic Interference (EMI) shielding, preventing signal degradation in noise-heavy environments. 4. **Environmental Sealing:** The "GR" suffix often denotes specific hardware or grommet/seal configurations designed to prevent moisture ingress and outgassing in vacuum environments. --- ### ### Application Use Cases * **Aerospace:** Avionics control systems and satellite communication. * **Defense:** Tactical radios, handheld displays, and missile guidance. * **Industrial:** Down-hole drilling equipment where high temperatures and vibrations are present. --- ### ### Pinout Configuration (Standard 9-Pin Micro-D) ```text 1 2 3 4 5 o o o o o o o o o 6 7 8 9 ```
