The **M2CE-1A-R/N** is a specific model within the **M2CE series** of industrial control components, primarily manufactured by companies like **Omron**. This part is a **Round, Non-lighted Pushbutton Switch** designed for panel mounting in automation and control circuits. ### 1. Part Number Breakdown Understanding the suffix codes helps identify the specific electronic and physical characteristics: | Component Code | Description | Details | | :--- | :--- | :--- | | **M2CE** | Series Name | Miniature Control Unit (Round type) | | **1A** | Contact Configuration | SPDT (Single Pole Double Throw) | | **R** | Button Color | Red | | **N** | Lighting Type | Non-lighted (Mechanical only) | --- ### 2. Technical Specifications These parts are engineered for reliability in industrial environments. Below are the typical electronic and mechanical ratings: * **Contact Type:** SPDT (1c contact). This means it can be used for both Normally Open (NO) and Normally Closed (NC) operations. * **Action Type:** Momentary (The switch returns to its original position immediately after being released). * **Rated Voltage/Current:** * *AC:* Typically 125V @ 5A or 250V @ 3A. * *DC:* Typically 30V @ 3A. * **Insulation Resistance:** 100 MΩ minimum. * **Dielectric Strength:** 1,000 VAC, 50/60 Hz for 1 minute between terminals of the same polarity. * **Mechanical Life:** 1,000,000 operations minimum. --- ### 3. Physical & Installation Features The M2CE series is known for its compact "miniature" footprint, saving space on control desks. * **Mounting Hole:** Usually requires a **12mm diameter** circular cutout. * **Terminal Type:** Solder terminals (Standard) or Tab terminals. * **IP Rating:** Generally IP40 (Dust-protected), though some variants offer higher sealing. * **Shape:** Round bezel and round button surface. --- ### 4. Common Applications Due to its SPDT configuration and momentary action, the M2CE-1A-R/N is frequently used for: 1. **Reset Buttons:** Clearing errors in a PLC (Programmable Logic Controller) circuit. 2. **Manual Overrides:** Temporarily triggering a relay or motor starter. 3. **Signal Inputs:** Providing a manual pulse to digital counters or timers. 4. **Emergency Stop (Non-Latching):** Basic manual interruption where a full locking E-stop is not required by safety code.
