The **M2REB-R2A-R2/CE** is a specific electronic component, typically identified as a **Limit Switch** or **Position Switch** within industrial automation systems. These parts are designed to detect the presence or position of an object through physical contact. ### 1. Key Technical Specifications Below is a breakdown of the typical electronic and mechanical characteristics of this series: | Feature | Specification Details | | :--- | :--- | | **Component Type** | Electromechanical Limit Switch | | **Contact Configuration** | Usually 1NO (Normally Open) + 1NC (Normally Closed) | | **Rated Voltage** | 250V AC / 24V DC (Standard Industrial) | | **Thermal Current (Ith)** | 10A | | **Actuator Type** | Roller Lever (indicated by the 'R' suffix) | | **Certification** | CE (European Conformity) | --- ### 2. Electronic Operating Principles The device operates on a simple but robust electronic mechanism: 1. **Mechanical Actuation:** A physical object hits the roller lever. 2. **Internal Shifting:** The movement triggers a spring-loaded "Snap Action" or "Slow Action" contact block inside the housing. 3. **Circuit Completion:** * The **NC (Normally Closed)** contact opens, breaking the circuit (used for emergency stops). * The **NO (Normally Open)** contact closes, completing the circuit (used to send a signal to a PLC). ### 3. Component Breakdown * **Housing:** Typically made of glass-reinforced polymer or die-cast metal to provide protection against environmental factors (IP65/IP67 rating). * **Contact Block:** The core electronic part where the wiring is connected via screw terminals. * **Head Assembly:** The R2/CE designation often refers to the specific head style (Roller) and the compliance standard (CE). ### 4. Common Applications * **Conveyor Systems:** Detecting the arrival of a package. * **Safety Interlocks:** Ensuring a machine guard is closed before power is supplied. * **Machine Tools:** Limiting the travel distance of a moving axis. ---
