The part number **1663242** is primarily associated with industrial automation components, specifically those manufactured by **Phoenix Contact**. This part is a specialized power distribution module or terminal block component used in control cabinets. ### Component Overview: 1663242 (CK2,5-ED-0,50ST AU) In the context of electronic hardware, this specific part number refers to a **Crimp Contact** used in heavy-duty connectors. These are essential for creating reliable, modular electrical connections in harsh environments. --- ### Technical Specifications | Feature | Details | | :--- | :--- | | **Manufacturer** | Phoenix Contact | | **Type** | Turned Crimp Contact (Male/Pin) | | **Contact Surface** | Gold-plated (AU) | | **Wire Gauge (AWG)** | 20 AWG | | **Cross Section** | 0.5 mm² | | **Current Rating** | Up to 16 A (depending on housing) | | **Connection Method** | Crimp connection | | **Series** | CK2,5 | --- ### Key Features and Material Properties * **Gold Plating:** The "AU" suffix indicates a gold-plated finish. Gold is used to prevent oxidation and ensure low contact resistance over long periods, making it ideal for low-voltage signal transmission or sensitive electronic circuits. * **Turned Contacts:** Unlike stamped contacts, "turned" contacts are machined from solid material. This provides higher mechanical stability and better conductivity. * **Vibration Resistance:** The crimping process creates a "cold weld" between the wire and the contact, making it highly resistant to mechanical stress and vibration compared to soldering. ### Applications These electronic parts are typically found in: 1. **Industrial Machinery:** Connecting sensors and actuators to a main control panel. 2. **Robotics:** Handling signals in articulated arms where flexibility and reliability are required. 3. **Renewable Energy:** Used in solar or wind turbine control systems to withstand outdoor environmental factors. --- ### Tools Required for Installation To use the 1663242 contact correctly, specific tooling is required to ensure the crimp meets industrial standards: | Tool Category | Purpose | | :--- | :--- | | **Crimping Pliers** | To compress the contact onto the wire (e.g., CK2,5-ED-0,50ST). | | **Extraction Tool** | To remove the contact from the connector insert without damage. | | **Contact Insert** | The plastic housing (HEAVYCON series) that holds the pins in place. |
