The **UTO2** (often associated with high-density circular connectors like the **Souriau UTS/UTO series**) is a rugged, industrial-grade interconnect system. These parts are designed to bridge the gap between heavy-duty performance and compact electronic design. --- ### 1. Key Electronic Components of the UTO Series The UTO2 system is modular, meaning the "part" consists of several integrated electronic and mechanical elements: | Component | Description | Material/Function | | :--- | :--- | :--- | | **Shell (Housing)** | The outer metal casing. | Zinc alloy with Nickel plating for EMI shielding. | | **Inserts** | The internal dielectric block that holds contacts. | Thermoplastic with high insulation resistance. | | **Contacts** | The actual conductive elements (Pins/Sockets). | Copper alloy with Gold or Tin plating. | | **Sealing Glands** | Components ensuring environmental protection. | Silicone or Neoprene for IP68/69K ratings. | --- ### 2. Technical Specifications Electronic performance is dictated by the contact density and the gauge of wire used. * **Voltage Rating:** Typically ranges from **250V to 500V** depending on the arrangement. * **Current Rating:** * *Signal Contacts:* ~7A to 13A. * *Power Contacts:* Up to 45A for specialized inserts. * **Insulation Resistance:** $\geq 5000\ M\Omega$ under standard conditions. * **Shielding:** 360° EMI/RFI shielding capability due to the metallic shell construction. --- ### 3. Connection Interface The electronic connection is established through specific contact types: 1. **Crimp Contacts:** High-reliability, vibration-resistant permanent connections. 2. **Solder Cup:** Used for manual assembly or prototyping. 3. **PCB Pins:** Used when the connector is mounted directly onto a Printed Circuit Board (common in UTO2 receptacle types). --- ### 4. Comparison: UTO vs. UTS While they share the same footprint, their electronic environments differ: | Feature | UTO Series | UTS Series | | :--- | :--- | :--- | | **Body Material** | Metal (Zinc/Aluminum) | Plastic (High-performance Polymer) | | **Shielding** | Superior (Faraday Cage effect) | Limited/None | | **Environment** | Heavy Industrial / High EMI | Corrosive / Outdoor / UV Exposed | ---
