The **WMS2-G3-R/Q** is a high-performance, compact, wire-to-board connector assembly, typically associated with automotive-grade or high-reliability industrial sensing applications. These components are often part of a series used in pressure sensors or specialized harness interfaces. ### Technical Specifications | Feature | Description | | :--- | :--- | | **Component Type** | Wire-to-Board / Connector Assembly | | **Material Housing** | High-temperature Thermoplastic (PBT or similar) | | **Contact Material** | Copper Alloy (often Gold or Tin plated) | | **Mounting Type** | Through-hole or Surface Mount (model dependent) | | **Pitch** | Variable (typically 1.25mm to 2.5mm series) | | **Compliance** | RoHS Compliant, AEC-Q100 (if automotive grade) | --- ### Key Electronic Attributes #### 1. Signal Integrity The "G3" designation usually refers to the generation or a specific gold-plating thickness on the contacts. This ensures low contact resistance and prevents oxidation, which is critical for low-voltage sensor signals. #### 2. Environmental Ruggedness The "R/Q" suffix often denotes specific packaging or qualification standards: * **R:** Often indicates "Reel" packaging for automated pick-and-place assembly. * **Q:** Can indicate "Quality" or "Automotive Grade" testing, ensuring the part can withstand high vibration and thermal cycling (-40°C to +125°C). #### 3. Mechanical Locking These parts usually feature a positive locking mechanism (click-lock) to prevent accidental disconnection in high-vibration environments like engine bays or industrial machinery. ### Application Use-Cases * **Automotive Sensors:** Used in MAP (Manifold Absolute Pressure) or TMAP sensors. * **Industrial Automation:** Connecting PLC units to small-form-factor actuators. * **Consumer Electronics:** High-density power distribution on PCBs. --- ### Comparison with Standard Connectors | Feature | WMS2-G3 Series | Standard Commercial | | :--- | :--- | :--- | | **Vibration Resistance** | High (Locking) | Low (Friction fit) | | **Plating** | Selective Gold/High-Grade Tin | Standard Tin | | **Operating Temp** | Up to 125°C | Up to 85°C |
