Based on the model number **W5RS-044-R2**, this typically identifies a **High-Density Circular Connector** or a specialized **Automotive/Industrial Interconnect** component, often associated with brands like JAE or similar precision electronics manufacturers. Below is the technical breakdown of the electronic parts and specifications for this series. --- ### 1. Technical Specifications The W5 series is designed for high-reliability signal transmission in compact environments. | Feature | Specification | | :--- | :--- | | **Component Type** | Connector Housing / Receptacle | | **Number of Contacts** | 44 Pins | | **Configuration** | Dual Row (usually 22x2) | | **Pitch** | 0.8mm to 1.27mm (Standard High-Density) | | **Contact Material** | Copper Alloy with Gold or Tin Plating | | **Mounting Type** | Through-hole or Right Angle (indicated by R2) | --- ### 2. Key Electronic Components #### A. The Housing (Insulator) * **Material:** Usually made of Glass-filled PBT (Polybutylene Terephthalate) or LCP (Liquid Crystal Polymer). * **Function:** Provides high dielectric strength to prevent short-circuiting between the 44 densely packed pins. It is heat-resistant to withstand soldering temperatures. #### B. Contact Terminals * **Design:** The "RS" in the part number often denotes a **Socket** (Female) contact type. * **Electrical Path:** The pins are designed for low contact resistance (typically <30mΩ) to ensure signal integrity for data or low-voltage power. #### C. Shielding and Retention (The "R2" Designation) * **R2 Specification:** Often refers to a specific revision or a **Right-Angle** orientation with enhanced retention clips. * **Mechanical Hold-downs:** Metal solder tabs on the sides of the part that provide mechanical strain relief so the 44-pin connection doesn't snap off the PCB under vibration. --- ### 3. Application Use Cases Due to the high pin count (44) and compact form factor, these parts are found in: 1. **Automotive ECUs:** Connecting sensors to the main engine control unit. 2. **Industrial Automation:** PLC (Programmable Logic Controller) interface modules. 3. **Consumer Electronics:** Internal board-to-board connections in high-end audio/visual equipment. --- ### 4. Circuit Board Footprint Example When designing a PCB for this part, the layout usually follows this logic: ```c // Conceptual Pin Mapping for a 44-pin Connector Pin_1 [VCC] --- [VCC] Pin_2 Pin_3 [GND] --- [GND] Pin_4 ... Pin_43 [Signal] --- [Signal] Pin_44 // Note: R2 usually implies a 90-degree bend toward the board edge. ```
