The **KLS-3-2-R/Q** is a specific model of an electronic component, typically categorized as a **Circular DIN Connector** (Mini-DIN) or a specific **Socket/Jack** assembly. These parts are widely used in older computing peripherals (PS/2), audio-visual equipment, and low-voltage power connections. --- ### 1. Technical Specifications Below are the typical technical parameters for this electronic part: | Parameter | Specification | | :--- | :--- | | **Component Type** | Mini-DIN Jack / Connector | | **Number of Pins** | 3 Pins | | **Configuration** | Right Angle (R) / Square Profile (Q) | | **Mounting Type** | Through-Hole (PCB Mount) | | **Current Rating** | 1A - 2A DC | | **Voltage Rating** | 12V - 100V AC/DC | | **Contact Resistance** | ≤ 30mΩ | | **Insulation Resistance** | ≥ 100MΩ at 250V DC | --- ### 2. Breakdown of the Model Name Electronic manufacturers (like KLS Electronic) often use an alphanumeric code to define the part's physical characteristics: * **KLS**: The manufacturer prefix (KLS Electronic). * **3**: Indicates the number of positions/pins (3-pin layout). * **2**: Often refers to the series or the specific mold design. * **R**: **Right Angle**. This means the pins are bent at a 90-degree angle so the connector sits parallel to the PCB. * **Q**: Usually stands for **Shielded** or a specific **Square** housing footprint, providing mechanical stability when soldered. --- ### 3. Key Electronic Features * **Shielding:** The "Q" variant usually features a metal outer shell. This acts as a common ground and protects the signal from Electromagnetic Interference (EMI). * **Durability:** Designed for high insertion cycles (typically 1,000 to 5,000 cycles). * **Material:** * **Housing:** PBT or Nylon (Thermoplastic) UL94V-0 rated. * **Contacts:** Copper alloy with Gold or Tin plating to prevent oxidation and ensure high conductivity. --- ### 4. Common Applications Due to its 3-pin configuration and right-angle PCB mount, this part is commonly found in: 1. **DC Power Input:** Used in small electronic devices as a locking power jack. 2. **Audio/Video:** S-Video connections or specialized balanced audio signals. 3. **Communication:** Low-speed data transmission for sensors or proprietary diagnostic tools. ---
