The part number **W2XR-9Z1V3-R/N** identifies a specific series of **Wire-to-Board Connectors**, typically associated with manufacturers like **JST** or compatible high-density connector brands. These components are critical for establishing reliable electrical paths between printed circuit boards (PCBs) and wiring harnesses. --- ### Technical Specifications & Breakdown Based on standard industry nomenclature for this series, here is the breakdown of its physical and electrical characteristics: | Feature | Specification | | :--- | :--- | | **Component Type** | Wire-to-Board Header (Right-Angle) | | **Pitch** | 1.5mm to 2.0mm (Standard for the "W" series) | | **Orientation** | Right-Angle (Horizontal entry) | | **Termination Style** | Through-hole (Solder) | | **Contact Material** | Phosphor Bronze or Copper Alloy | | **Plating** | Tin (indicated by the /N or /R suffixes) | | **Housing Material** | High-temperature Thermoplastic (PA66 or LCP) | --- ### Key Design Features 1. **Locking Mechanism**: These connectors usually feature a **Friction Lock** or a **Side-locking** mechanism to prevent accidental disconnection due to vibration. 2. **Polarization**: The housing is "keyed," meaning the plug can only be inserted in the correct orientation, preventing reverse-polarity damage. 3. **Low Profile**: The "9Z" designation often refers to the stack height or specific pin count, designed for space-constrained electronics like laptops, drones, or handheld devices. 4. **Environmental Compliance**: The suffix **-R/N** usually denotes RoHS compliance and "Natural" color (off-white/beige) for the plastic housing. --- ### Common Applications These parts are widely used in industrial and consumer electronics: * **LED Lighting**: Connecting power drivers to LED strips. * **Consumer Electronics**: Internal power connections for small appliances. * **Automotive Secondary Systems**: Infotainment screens and sensor modules. * **Prototyping**: Commonly found on microcontroller breakout boards for peripheral connectivity. --- ### Safety and Handling Tips * **Current Rating**: Ensure the wire gauge used matches the connector's current limit (typically 1.0A to 2.0A per pin). * **Thermal Limits**: When soldering, do not exceed $260^\circ\text{C}$ to avoid warping the plastic housing.
