The **W2AP-333-R** is a specific electronic component, typically categorized as a **Terminal Block** or **PCB Connector**, often associated with manufacturers like *Weco* or similar industrial interface brands. Below is a detailed breakdown of its electronic and mechanical parts. --- ### 1. General Specifications The W2AP-333-R is designed for high-density wire-to-board connections. | Feature | Specification | | :--- | :--- | | **Component Type** | Terminal Block / PCB Header | | **Mounting Type** | Through-Hole (THT) or Right Angle | | **Pitch** | Typically 3.5mm or 5.0mm (varies by sub-series) | | **Current Rating** | Generally 8A - 12A | | **Voltage Rating** | 150V - 300V AC | | **Material** | Polyamide (PA66) / Brass (Tin-plated) | --- ### 2. Electronic & Mechanical Parts Breakdown #### A. The Housing (Insulator) * **Material:** Usually high-grade Polyamide (UL94V-0 rated). * **Function:** Provides electrical isolation between adjacent pins and protects the internal contacts from environmental debris. It is designed to withstand soldering heat during the assembly process. #### B. The Pin Header (Conductive Path) * **Material:** Brass or Phosphor Bronze with Tin or Gold plating. * **Function:** This is the primary conductive element. The pins are soldered into the PCB (Printed Circuit Board). The "R" in the part number often denotes a **Right Angle** orientation, meaning the pins are bent at 90 degrees to allow for side-entry cabling. #### C. Locking/Latch Mechanism * **Mechanism:** Most W2AP series parts feature a friction lock or a mechanical latch. * **Function:** Ensures that the mating plug (the part attached to the wires) does not vibrate loose or disconnect accidentally. --- ### 3. Application Use Cases Because of its compact footprint and reliable current handling, the W2AP-333-R is commonly found in: 1. **Industrial Controllers:** Used for PLC inputs and outputs. 2. **Power Supplies:** Serving as the output interface for DC power. 3. **Sensor Hubs:** Connecting multiple low-voltage sensors to a main processing board. --- ### 4. Part Number Suffix Logic * **W2AP:** Series identifier (Plug-in header). * **333:** Specific pin spacing and configuration code. * **-R:** Usually signifies **Right Angle** orientation or **RoHS** compliance depending on the specific manufacturer's datasheet.
