The **M2VF-04W-R2** is a specific electronic component belonging to the **M2VF series**, manufactured by **JST (Japan Solderless Terminals)**. It is a high-density, wire-to-board connector housing designed for compact electronic assemblies. --- ## Technical Specifications | Feature | Details | | :--- | :--- | | **Manufacturer** | JST (Japan Solderless Terminals) | | **Series** | M2VF Series | | **Part Number** | M2VF-04W-R2 | | **Number of Positions** | 4 Circuits (Pins) | | **Pitch** | 2.0 mm | | **Connector Type** | Crimp Housing (Socket) | | **Mounting Type** | Free Hanging (In-Line / Wire-to-Board) | | **Color** | White / Natural (R2 often denotes specific packaging or material variants) | --- ## Key Components and Design Features ### 1. Housing Material The body is typically made of **Nylon 66 (UL94V-0)**. This provides excellent thermal resistance and electrical insulation, ensuring the connector can withstand operating temperatures commonly found in consumer electronics. ### 2. Contact System The "04W" indicates a 4-wire configuration. This part is the **housing only**; it requires crimp terminals (contact pins) to be inserted into the cavities. * **Secondary Lock:** The M2VF series often features a secondary locking mechanism to prevent terminal back-out (accidental disconnection due to vibration). ### 3. Mechanical Interface * **Polarization:** The housing is keyed to ensure it can only be plugged into the mating header in the correct orientation. * **Locking Mechanism:** It features a friction lock or a small latching arm that provides a secure "click" when mated, preventing the connector from shaking loose. --- ## Applications The M2VF series is widely used in industries requiring high-density connections where space is limited: * **Consumer Electronics:** LCD televisions, gaming consoles, and audio equipment. * **Office Automation:** Printers, copiers, and scanners. * **Industrial Controls:** Small-scale sensor interfaces and PLC modules. --- ## Recommended Mating and Tooling To use the M2VF-04W-R2, you generally need the following compatible parts: 1. **Terminals:** Crimp contacts compatible with the M2VF series (e.g., SVF-01T-1.5N). 2. **Mating Header:** A 2.0mm pitch M2VF series wafer/header mounted on a PCB. 3. **Crimping Tool:** A manual or semi-automatic JST crimping tool to attach the wires to the metal terminals.
