The **M2MS-6-R2/K** is a specific model within the series of high-performance magnetic sensors, typically used in industrial automation for position detection and cylinder monitoring. ### 1. Technical Specifications Below is a breakdown of the electronic and physical characteristics of this component: | Feature | Specification | | :--- | :--- | | **Sensor Type** | Magnetic Reed Switch / Magnetoresistive | | **Contact Form** | Normally Open (NO) | | **Operating Voltage** | 5V - 120V AC/DC (Typical range) | | **Switching Current** | Max 100mA | | **Switching Power** | Max 10W | | **Voltage Drop** | $\leq$ 2.5V | | **Indicator** | Red LED (Standard for 'R2' designation) | | **Connection** | Cable / M8 or M12 Circular Connector (K-version) | --- ### 2. Electronic Components & Working Principle The "M2MS" series usually relies on one of two internal electronic mechanisms: * **The Reed Switch:** Consists of two ferromagnetic blades sealed in a glass tube. When a magnetic field (from a piston or actuator) approaches, the blades pull together to close the circuit. * **LED Protection Circuit:** The "R2" suffix usually indicates an integrated protection circuit with a light-emitting diode (LED). This allows technicians to visually confirm when the sensor has been triggered. * **Varistor/Zener Diode:** Often included internally to protect the contacts from voltage spikes caused by inductive loads. --- ### 3. Naming Convention Breakdown The alphanumeric code provides specific details about the electronic configuration: * **M2MS:** Product series identifier (Miniature Magnetic Sensor). * **6:** Designates the housing size or mounting profile (often 6mm or C-slot compatible). * **R2:** Refers to the electronic output type—Standard Reed switch with 2-wire configuration and LED. * **K:** Usually indicates a **Quick Disconnect** (Connector) rather than a pre-wired flying lead. --- ### 4. Typical Wiring Diagram Since this is a 2-wire device, it is wired in series with the load. ```mermaid graph LR A[Power +] --- B[Load/PLC Input] B --- C[M2MS Sensor] C --- D[Power - / Common] ``` > **Note:** Ensure that the current limit (100mA) is not exceeded, as reed switches can weld shut if subjected to a short circuit or high inrush current.
