The **M2AS1-4344-R/CE** is a specific variant of an industrial-grade **M12 A-coded Connector**, typically used in automation, sensor integration, and fieldbus systems. It is designed for robust electrical connections in harsh environments. ### 1. Technical Specifications Overview | Parameter | Specification Details | | :--- | :--- | | **Connector Type** | M12 Circular Connector | | **Coding** | A-coded (Standard for sensors, actuators, and DC power) | | **Gender** | Male (Plug) | | **Number of Pins** | 4-Pin configuration | | **Mounting Type** | Solder or Screw termination (depending on specific sub-series) | | **Orientation** | Straight or Right Angle (indicated by the 'AS' series) | | **Protection Class** | IP67 or IP68 (Waterproof and Dust-tight) | --- ### 2. Key Electronic Components & Materials The reliability of this part depends on the quality of its internal electronic and mechanical components: * **Contacts:** Usually made of **Brass or Phosphor Bronze** with **Gold (Au) plating**. Gold is used to prevent oxidation and ensure low contact resistance over thousands of mating cycles. * **Insulator:** High-temperature plastic (often **PA66 or PBT**). This provides high dielectric strength to prevent short-circuiting between the 4 pins. * **Coupling Nut:** Nickel-plated brass or stainless steel. This provides the mechanical "ground" and ensures the connection remains secure under vibration. * **O-Ring/Seals:** Viton or NBR rubber, providing the environmental seal (IP rating) against oils and moisture. --- ### 3. Electrical Characteristics The M2AS1 series typically adheres to the following electrical limits: 1. **Rated Voltage:** Up to 250V AC/DC (standard for 4-pin A-coded). 2. **Rated Current:** Usually 4A per contact. 3. **Contact Resistance:** ≤ 5 mΩ. 4. **Insulation Resistance:** ≥ 100 MΩ. --- ### 4. Typical Applications * **Sensors/Actuators:** Connecting Proximity switches, photoelectric sensors, and limit switches to PLC I/O modules. * **Industrial Ethernet:** While D-coded is more common for high-speed data, A-coded is used for basic data and power delivery in CANopen or DeviceNet systems. * **Robotics:** Used in end-of-arm tooling where space is tight and vibration resistance is mandatory. ---
