The **M2AS1-6311-R/CE** is a specific part number typically associated with **Industrial Control Switches**, specifically from the **M2 series** of push-button switches (often manufactured by companies like DECA Switchlab). Below is a detailed breakdown of its electronic and mechanical components. --- ### 1. General Specifications This part is a **16mm Pilot Lamp / Push Button Switch**. The alphanumeric code defines its specific configuration: | Feature | Specification | | :--- | :--- | | **Mounting Diameter** | 16mm (Circular) | | **Action Type** | Alternate (Latching) - Push to stay, Push to release | | **Contact Block** | 1a1b (1 Normally Open + 1 Normally Closed) | | **Illumination** | LED Integrated | | **Shape** | Square (S1 designation) | | **Color** | Red (R designation) | --- ### 2. Electronic Component Breakdown #### A. Contact Block (Switching Mechanism) The "63" in the code typically refers to the contact arrangement. * **Gold-Clad Silver Contacts:** These are used to ensure low contact resistance and high reliability, even in low-current logic circuits. * **1a1b Configuration:** This means the switch contains one set of **Normally Open (NO)** contacts and one set of **Normally Closed (NC)** contacts. #### B. Illumination (The LED System) The "11" in the suffix usually denotes the voltage and lamp type: * **Light Source:** High-brightness LED. * **Voltage:** Commonly rated for **24V AC/DC** (though this should be verified against the specific datasheet as "11" can sometimes refer to 110V depending on the manufacturer's series update). * **Current Draw:** Typically very low (approx. 15-20mA), making it compatible with PLC outputs. #### C. Terminal Design * **Solder/Plug-in Terminals:** The pins are designed to be either soldered directly to wires or plugged into a matching socket (Solder terminal type). * **Protection:** Rated **IP40** or **IP65** (depending on the "CE" sealing certification), meaning it is protected against dust and, in some versions, water splashes. --- ### 3. Electrical Ratings To ensure the part functions correctly within a circuit, it must adhere to these limits: | Parameter | Value (Typical) | | :--- | :--- | | **Rated Thermal Current ($I_{th}$)** | 5A | | **Rated Insulation Voltage ($U_i$)** | 250V AC | | **Contact Resistance** | 50m$\Omega$ Max (Initial) | | **Electrical Life** | > 100,000 operations | | **Mechanical Life** | > 1,000,000 operations | --- ### 4. Part Number Decoder (M2AS1-6311-R/CE) * **M2:** Series name (16mm Miniature Switches). * **A:** Alternate (Latching) action. * **S1:** Square Head shape. * **63:** Contact configuration (1NO+1NC). * **11:** Lamp Voltage/Type. * **R:** Red Color. * **CE:** Meets European Safety Standards (Conformité Européenne).
