The **WMS-2C-R** typically refers to a **Wire-to-Board or Wire-to-Wire Miniature Connector System**, often associated with brands like JST or similar electronic component manufacturers. These are designed for high-density applications where space is limited. Below is a technical breakdown of its electronic and physical characteristics. ### 1. General Specifications | Feature | Specification | | :--- | :--- | | **Part Series** | WMS (Miniature Series) | | **Circuit Count** | 2 Circuits (Pins) | | **Type** | C-Type (Housing/Plug) | | **Mounting** | Wire Mount (Crimp Type) | | **Pitch** | Typically 2.0mm or 2.5mm (Series dependent) | --- ### 2. Key Electronic Components The "WMS-2C-R" is an assembly consisting of several electronic sub-parts: #### A. The Housing (The "R" suffix) The **R** often denotes the **Receptacle** or the housing unit. * **Material:** Usually Nylon 66 (UL94V-0 rated for flame retardancy). * **Function:** It acts as the insulator, preventing short circuits between the two pins while providing mechanical alignment. #### B. Crimp Terminals While the housing is the plastic shell, the electronic conductivity is handled by metal terminals (sold separately or pre-installed). * **Material:** Phosphor bronze or Brass. * **Plating:** Tin-plated (most common) or Gold-plated for high-reliability signals. * **Current Rating:** Typically ranges from **1A to 3A AC/DC** depending on wire gauge. #### C. Locking Mechanism * **Friction Lock:** Most WMS series use a friction-fit or a small plastic ramp to ensure the connector does not vibrate loose during operation. --- ### 3. Electrical Characteristics | Parameter | Standard Value | | :--- | :--- | | **Voltage Rating** | 125V - 250V AC/DC | | **Insulation Resistance** | 1000 MΩ Minimum | | **Withstanding Voltage** | 800V - 1000V AC/minute | | **Contact Resistance** | Max 20mΩ | | **Operating Temperature** | -25°C to +85°C | --- ### 4. Common Applications Due to its miniature size and 2-pin configuration, the WMS-2C-R is frequently used for: * **Battery Connections:** Small Li-Po battery packs. * **LED Modules:** Powering strips or individual status LEDs. * **Fan Headers:** Small cooling fans in compact electronics. * **Sensor Interfacing:** Connecting 2-wire sensors to a PCB.
