The **M2PHS2L-16A-R/N** is a specific part number typically associated with **industrial limit switches** or **microswitches**, often manufactured by companies like Moujen or similar industrial control brands. Below is a breakdown of its electronic and mechanical specifications. --- ### 1. Part Number Breakdown While nomenclature can vary slightly by manufacturer, here is the standard interpretation for this series: | Component | Identifier | Description | | :--- | :--- | :--- | | **Series** | M2PH | Miniature/Industrial high-precision switch body. | | **Actuator** | S2L | Short hinge roller lever (standard for cam or slide sensing). | | **Current Rating** | 16A | Rated for a maximum of 16 Amperes. | | **Contact Form** | R/N | SPDT (Single Pole Double Throw) configuration. | --- ### 2. Electrical Specifications These switches are designed for robust electrical performance in automated systems. * **Current Rating:** 16A at 250VAC (Resistive load). * **Insulation Resistance:** 100MΩ min. (at 500VDC). * **Contact Resistance:** 15mΩ max. (initial). * **Dielectric Strength:** 1,000VAC (50/60Hz for 1 minute between non-continuous terminals). * **Service Life:** * *Mechanical:* Over 10,000,000 operations. * *Electrical:* Over 100,000 operations at full load. --- ### 3. Mechanical & Physical Properties The "S2L" designation refers specifically to the hardware used to trigger the switch. * **Actuator Type:** Short Hinge Roller Lever. This is used when the trigger mechanism involves a sliding motion or a cam, as the roller reduces friction and wear. * **Housing Material:** High-grade Phenolic or PBT plastic (heat and impact resistant). * **Terminal Type:** Solder/Quick-connect terminals (typically 4.8mm or 6.3mm tabs). * **Operating Force (OF):** Usually ranges between 150g to 250g depending on the lever length. --- ### 4. Circuit Diagram (SPDT) The internal electronic structure follows a standard Single Pole Double Throw logic: ```mermaid graph LR COM[Common Terminal] --- NC[Normally Closed] COM -.-> NO[Normally Open] ``` * **COM (Common):** The input power/signal. * **NC (Normally Closed):** Connected to COM when the lever is at rest. * **NO (Normally Open):** Connects to COM only when the roller lever is depressed. --- ### 5. Common Applications * **Industrial Automation:** Conveyor belt limit sensing. * **Safety Interlocks:** Detecting if a machine door or guard is closed. * **Home Appliances:** High-current triggers in HVAC or large white goods. * **CNC Machinery:** Axis end-stop detection.
