The **M2PHSW-A1-R2/CE** is a specialized industrial electronic component, typically categorized as a **Limit Switch** or **Position Switch**, often associated with the **M2P series** produced by manufacturers like **Moujen** or similar industrial control brands. Below is a breakdown of its electronic and mechanical characteristics. --- ### 1. Technical Specifications Table | Feature | Specification Details | | :--- | :--- | | **Component Type** | Heavy-duty Limit Switch / Micro Switch | | **Actuator Type** | Side Rotary (Adjustable Roller Lever) | | **Contact Configuration** | 1NO (Normally Open) + 1NC (Normally Closed) | | **Rated Voltage** | 250V AC / 125V DC (Typical) | | **Current Rating** | 10A (Resistive Load) | | **Protection Rating** | IP65 / IP67 (Dust-tight and Water-resistant) | | **Body Material** | Die-cast Aluminum / Zinc Alloy | | **Certification** | CE (European Conformity) | --- ### 2. Electronic Component Breakdown #### A. Contact Block Mechanism The internal "heart" of the switch usually consists of a **Double-break contact mechanism**. * **1NO + 1NC:** This allows for a "Changeover" function. When the lever is pushed, the closed circuit opens and the open circuit closes simultaneously. * **Bifurcated Contacts:** Often used to ensure high reliability even at low voltage/current (logic levels). #### B. The Actuator (R2 Suffix) The `R2` in the model name specifically refers to the **Adjustable Roller Lever**. * **Mechanical to Electronic Conversion:** The lever translates physical movement (e.g., a machine arm hitting the roller) into a mechanical force that triggers the internal microswitch. * **Adjustability:** The length of the arm can be adjusted to change the torque requirements or the reach of the switch. #### C. Circuitry and Terminals * **Screw Terminals:** Internally, the switch features three or four screw terminals for secure wiring. * **Conduit Entry:** The `A1` or specific housing codes usually indicate the size of the cable entry (e.g., G1/2" or M20 thread) for industrial electrical conduits. --- ### 3. Key Electronic Functions 1. **End-of-Travel Sensing:** Used to cut power to a motor once a part reaches a specific position. 2. **Safety Interlocking:** Used on machine doors; if the door opens, the switch breaks the circuit to stop the machine. 3. **Position Detection:** Sends a signal to a PLC (Programmable Logic Controller) to indicate that a process step is complete. --- ### 4. Environmental & Durability Features * **CE Marking:** Indicates compliance with EU safety, health, and environmental protection requirements. * **Sealings:** Includes rubber gaskets at the head and the conduit entry to prevent oil, water, or coolants from shorting the electronic contacts.
