The **MA6L1FBD-R** is a specific part number belonging to the **MA6 series** of industrial control switches, typically manufactured by companies like **DECA SwitchLab**. These components are modular, meaning they consist of an operator, a contact block, and sometimes an illumination element. --- ### 1. Technical Specifications The part number can be broken down into specific electronic and mechanical characteristics: | Feature | Specification | | :--- | :--- | | **Component Type** | Illuminated Push Button Switch | | **Mounting Diameter** | 16mm (Standard industrial cutout) | | **Circuit Configuration** | 1NO + 1NC (1 Normally Open, 1 Normally Closed) | | **Illumination Type** | LED (Integrated) | | **Voltage Rating** | Typically 24V AC/DC (Standard for the "F" suffix) | | **Terminal Type** | Solder/Plug-in Terminals | | **Action Type** | Momentary (Spring return) | | **Actuator Shape** | Flush Round | --- ### 2. Electronic Component Breakdown #### A. The Contact Block The "1F" in the code signifies the contact arrangement. - **1NO (Normally Open):** The circuit is open until the button is pressed. - **1NC (Normally Closed):** The circuit is closed until the button is pressed. - **Material:** Contacts are usually silver-plated or gold-plated to ensure low contact resistance and high reliability. #### B. The LED Module The "BD" and "R" segments usually refer to the electrical properties of the light source: - **Voltage:** Designed for low-voltage control circuits (typically 24V). - **Color (R):** Indicates a **Red** LED indicator. - **Polarity:** LEDs are polarity-sensitive, though some industrial modules include internal bridge rectifiers to allow for AC or DC operation. --- ### 3. Connection Diagram (General) The terminals are usually numbered to identify the LED and the switch contacts: ```text Terminal Layout: (+) [ L1 ] -- LED Positive (-) [ L2 ] -- LED Negative (1) [ NC ] -- Normally Closed Terminal (2) [ NC ] -- Normally Closed Common (3) [ NO ] -- Normally Open Terminal (4) [ NO ] -- Normally Open Common ``` --- ### 4. Applications Because of its 16mm size and integrated illumination, this part is commonly used in: * **Control Panels:** For status signaling (Red for Stop/Fault). * **Medical Equipment:** Compact interfaces requiring tactile feedback. * **Laboratory Instruments:** Where space is limited on the dashboard. * **Industrial Automation:** PLC input triggering and visual feedback.
