The **WEPA-12MBB-R** is a specific electronic component, typically categorized as a **Wire-to-Board (WTB) Connector** or a header assembly used in high-density electronic assemblies. The "12MBB" suffix usually denotes a 12-position, male, box-type header with a right-angle orientation. Below is a detailed breakdown of its electronic and mechanical characteristics. --- ### Technical Specifications | Feature | Description | | :--- | :--- | | **Connector Type** | Wire-to-Board Header | | **Number of Positions** | 12 Pins / Circuits | | **Pitch Spacing** | Commonly 2.0mm or 2.5mm (Series dependent) | | **Orientation** | Right-Angle (R) | | **Mounting Type** | Through-Hole (THT) | | **Contact Plating** | Tin or Gold-Flash | | **Current Rating** | Typically 1.0A to 3.0A per contact | | **Voltage Rating** | 125V - 250V AC/DC | --- ### Key Component Parts The WEPA-12MBB-R is composed of three primary sub-components: #### 1. The Insulator Body (Housing) * **Material:** Usually made of high-temperature Nylon or PBT (Polybutylene Terephthalate). * **Function:** It provides the mechanical structure, ensures pin-to-pin isolation, and often features a "shrouded" or "box" design to prevent incorrect mating (polarization). #### 2. Conductive Pins (Contacts) * **Material:** Phosphor Bronze or Brass. * **Design:** These are the male pins that interface with the female crimp housing. The "R" in the part number indicates these pins are bent at a 90-degree angle to sit flush with the PCB edge. #### 3. Solder Tails * **Function:** The portion of the pins that extend through the PCB holes. * **Finish:** Lead-free tin plating is standard to ensure compliance with RoHS regulations and to provide excellent solderability. --- ### Application Usage This component is widely used in the following sectors: * **Consumer Electronics:** Internal power and signal routing for appliances. * **Industrial Automation:** Sensor-to-controller interfaces. * **Automotive Secondary Systems:** Dashboard lighting or low-current signal modules. * **Computing:** Peripheral connections on motherboards or expansion cards. --- ### Schematic Symbol and Footprint When designing a PCB for this part, the engineer must account for: 1. **Pin 1 Indicator:** A square pad or notch on the housing to ensure correct orientation. 2. **Drill Diameter:** Usually 0.7mm to 0.9mm depending on pin thickness. 3. **Keep-out Zone:** Space required for the mating female connector to be plugged in horizontally.
