The **MA14FAX-R** is a specific part number typically associated with **M-Series Microswitches** or specialized electromechanical components produced by manufacturers like **Omron** or **Honeywell** (often used in security and industrial monitoring). It is an "Actuator Type" magnetic contact or reed switch assembly often used for alarm systems and position sensing. --- ### 1. Component Specifications Below is a breakdown of the typical technical attributes for this electronic part: | Parameter | Specification (Typical) | | :--- | :--- | | **Part Type** | Magnetic Reed Switch / Non-contact Interlock | | **Contact Configuration** | Normally Closed (NC) or CO (Changeover) | | **Max Switching Voltage** | 30V DC / 110V AC (varies by sub-model) | | **Max Switching Current** | 0.5A to 1.0A | | **Housing Material** | ABS Plastic or Aluminum | | **Connection Type** | Cable Lead (usually 2m to 5m) | | **Environmental Rating** | IP67 (Waterproof/Dustproof) | --- ### 2. Key Internal Electronic Parts The functionality of the MA14FAX-R relies on several core electronic principles: 1. **Reed Switch Capsule:** The heart of the device. It consists of two ferromagnetic blades (reeds) hermetically sealed in a glass tube. In the presence of a magnetic field, the reeds move to close or open the circuit. 2. **Internal Resistor (Optional):** Some "R" suffix models include an internal End-of-Line (EOL) resistor. This allows security panels to distinguish between a "closed door," an "open door," and a "tampered wire" (short circuit). 3. **Encapsulation Compound:** The internal electronics are potted with epoxy resin to prevent vibration damage and moisture ingress, ensuring long-term reliability in industrial environments. --- ### 3. Pinout and Wiring Logic While wiring can vary, the standard color-coding for these sensors usually follows this logic: | Wire Color | Function | Description | | :--- | :--- | :--- | | **Black/White** | Common (COM) | The main signal return path. | | **Red** | Normally Closed (NC) | Circuit is closed when the magnet is near. | | **Blue** | Normally Open (NO) | Circuit is open when the magnet is near. | --- ### 4. Applications The **MA14FAX-R** is commonly used in the following scenarios: * **Machine Guarding:** Ensuring a safety gate is closed before a machine starts. * **Security Systems:** High-reliability door and window monitoring. * **Pneumatics:** Detecting the end-of-stroke position for cylinders. ---
