The **M2VF2-012-R/UL** is a specific model of a **Miniature Intermediate Power Relay**, typically manufactured by brands like **Megatone** or similar electronic component suppliers. This relay is designed for PCB (Printed Circuit Board) mounting and is used to control a high-power circuit with a low-power signal. --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify the component's specifications: | Segment | Meaning | Specification | | :--- | :--- | :--- | | **M2V** | Series Code | Miniature Intermediate Power Relay | | **F2** | Contact Form | 2 Form C (DPDT - Double Pole Double Throw) | | **012** | Coil Voltage | 12V DC | | **R** | Feature | RoHS Compliant | | **UL** | Certification | UL (Underwriters Laboratories) Recognized | --- ### 2. Technical Specifications The following table outlines the typical electrical and physical characteristics of this part: | Parameter | Value | | :--- | :--- | | **Contact Arrangement** | 2 Form C (DPDT) | | **Max Switching Current** | 5A to 8A (depending on load type) | | **Max Switching Voltage** | 250V AC / 30V DC | | **Coil Nominal Voltage** | 12V DC | | **Coil Power Consumption** | Approx. 0.54W | | **Insulation Resistance** | 1,000 MΩ Min. (at 500V DC) | | **Dielectric Strength** | 5,000V AC (between coil and contacts) | | **Mounting Type** | Through-hole PCB | --- ### 3. Key Features * **High Sensitivity:** Requires relatively low power to trigger the coil. * **Safety Standards:** The "UL" designation confirms it meets North American safety requirements for flame retardancy and electrical insulation. * **Compact Footprint:** Designed for high-density PCB layouts where space is limited but high switching capacity is needed. * **Double Pole Double Throw (DPDT):** It can control two separate circuits simultaneously, making it versatile for reversing motor polarity or switching between two different power sources. --- ### 4. Common Applications 1. **Industrial Controls:** Used in PLC outputs to drive small motors or solenoids. 2. **Home Appliances:** Control boards for washing machines, HVAC systems, and refrigerators. 3. **Consumer Electronics:** Power management in audio-visual equipment. 4. **Automotive Electronics:** Signal switching for 12V DC systems (though usually indoor/protected environments). ---
