### Technical Overview: M2AS1-4142-R/CE The **M2AS1-4142-R/CE** is a specialized modular connector system, typically categorized under **M12 Circular Connectors**. These are widely used in industrial automation, sensor technology, and fieldbus systems due to their robustness and reliability in harsh environments. --- ### Key Technical Specifications The following table outlines the core electronic and mechanical characteristics of the M2AS1 series: | Parameter | Specification | | :--- | :--- | | **Connector Type** | M12 Circular Connector | | **Coding** | A-Coded (Standard for Sensors/DC Power) | | **Number of Poles** | 4-Pin / 2-Socket Configuration | | **Current Rating** | Typically 4A per contact | | **Voltage Rating** | 60V AC / 60V DC | | **Ingress Protection** | IP67 (Dust tight, immersion up to 1m) | | **Termination Style** | Screw or Solder (Model dependent) | | **Housing Material** | Nickel-plated Brass or Plastic | --- ### Electronic Components & Construction The device is comprised of several critical electronic sub-parts: 1. **Contacts (Pins/Sockets):** Usually made of a copper alloy with gold (Au) or nickel (Ni) plating. Gold plating ensures low contact resistance and prevents oxidation over long periods of use. 2. **Insulator/Insert:** A high-performance plastic (often TPU or PA66) that holds the pins in place and provides electrical isolation between the poles. 3. **Coupling Nut:** A threaded metal or plastic ring that provides the mechanical locking mechanism to ensure the electrical connection is not broken by vibration. 4. **O-Ring/Seals:** Internal rubber gaskets that provide the IP67 rating, protecting the electronic signal from moisture and contaminants. --- ### Common Applications * **Industrial Sensors:** Connecting Proximity, Photoelectric, and Ultrasonic sensors to a PLC. * **Actuators:** Powering small solenoid valves or motor starters. * **Data Transmission:** Used in CANbus or DeviceNet architectures (when A-coded). * **Factory Automation:** Standardized interface for robotic arms and conveyor systems. --- ### Wiring Configuration (A-Coding Standard) For a 4-pin A-coded configuration, the standard wiring is typically: 1. **Pin 1:** Brown (+24V DC) 2. **Pin 2:** White (Signal/NC) 3. **Pin 3:** Blue (0V / Ground) 4. **Pin 4:** Black (Signal/NO)
