The **M2TT-30-R/N** is a specific model of an **Industrial Limit Switch** or **Micro Switch**, commonly used in automation and control circuitry. Based on its nomenclature, this part typically belongs to heavy-duty limit switch series used for sensing physical presence or position. --- ## 1. Technical Specifications Below are the primary electronic and mechanical characteristics of the M2TT-30-R/N: | Feature | Specification | | :--- | :--- | | **Switch Type** | Roller Plunger Limit Switch | | **Contact Configuration** | 1NO + 1NC (Single Pole Double Throw - SPDT) | | **Current Rating** | 10A (AC-15) | | **Voltage Rating** | 250V AC / 115V DC | | **Actuator Type** | Cross Roller Plunger | | **Material** | Die-cast Aluminum / Zinc Alloy Housing | | **Protection Class** | IP67 (Dust tight and water immersion resistant) | --- ## 2. Component Breakdown The device consists of three main electronic and mechanical segments: ### A. The Contact Block This is the internal switching mechanism. * **1NO (Normally Open):** The circuit is open until the plunger is pressed. * **1NC (Normally Closed):** The circuit is closed until the plunger is pressed. * The contacts are usually made of **Silver Alloy** to reduce electrical resistance and prevent arcing. ### B. The Actuator (Roller Plunger) The "30-R" designation usually refers to the **Roller** mechanism. * **Function:** It converts physical motion into electrical signals. * **Application:** Ideal for cam-operated applications where the trigger mechanism moves laterally across the switch. ### C. The Housing (N Series) The "N" suffix often denotes a specific terminal type or conduit entry (often NPT threading or a specific connector type). * **Wiring:** Internally, it features screw terminals for easy wiring of industrial cables. * **Durability:** The casing acts as a Faraday cage to protect internal electronics from electromagnetic interference (EMI). --- ## 3. Wiring Logic When integrating the M2TT-30-R/N into a control system, the wiring logic is typically as follows: ```mermaid graph LR A[Power Supply] --> B{Limit Switch} B -- NC Terminal --> C[Stop Signal/Safety] B -- NO Terminal --> D[Indicator Light/Start] ``` --- ## 4. Key Applications * **CNC Machines:** To detect the home position or end-of-travel for the X/Y/Z axes. * **Conveyor Belts:** To count items or trigger a stop if a jam occurs. * **Safety Interlocks:** Ensuring a protective door is closed before a machine begins operation.
