The **M2MS-3-R** is a specific electronic component, typically categorized as a **Surface Mount (SMT) Magnetic Shielded Inductor** or a specialized **Micro-Switch/Sensor** depending on the specific manufacturer (most commonly associated with magnetic sensing or power management). Below is a technical breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The "M2MS" series is often designed for compact electronic circuits where space and electromagnetic interference (EMI) management are critical. | Feature | Specification | | :--- | :--- | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Number of Pins/Terminals** | 3 | | **RoHS Status** | Compliant (Lead-free) | | **Packaging** | Tape & Reel (indicated by the "-R" suffix) | --- ### 2. Pin Configuration and Internal Logic As a 3-pin component, the M2MS-3-R typically follows a standard transistor-style or sensor-style footprint (like SOT-23). * **Pin 1 (Input/Supply):** Receives the primary voltage or signal. * **Pin 2 (Ground/Common):** The reference point for the circuit. * **Pin 3 (Output):** The switched or filtered signal output. --- ### 3. Key Electronic Functions Depending on the specific application in your circuit, the M2MS-3-R performs one of the following roles: #### A. Magnetic Sensing (Hall Effect/Reed) If used as a sensor, the device detects the presence of a magnetic field. * **Contact Form:** Usually SPDT (Single Pole Double Throw) or a simple Normally Open (NO) switch. * **Switching Voltage:** Typically rated for low-power signals (up to 30V DC). #### B. EMI Filtering / Inductance If used as a power component: * **Magnetic Shielding:** The "MS" in the name often denotes "Magnetic Shield," which prevents the component's magnetic field from interfering with neighboring components on a crowded PCB. * **High Impedance:** Designed to suppress high-frequency noise in data lines. --- ### 4. Part Number Decoder Understanding the suffix and prefix: | Code | Meaning | | :--- | :--- | | **M2MS** | Series Identifier (Micro-Magnetic Shielded/Sensor) | | **3** | Number of active terminals/poles | | **-R** | **RoHS Compliant** and/or **Tape & Reel** packaging for automated assembly. | --- ### 5. Common Applications * **Mobile Devices:** Lid sensors for laptops or flip phones. * **Power Supplies:** Small-scale DC-DC converters requiring shielded inductors. * **Automotive:** Interior lighting triggers or proximity detection.
