The **M8TS-044-R/BL** refers to a specific series of **M8 Circular Connectors**. These are widely used in industrial automation for connecting sensors, actuators, and Fieldbus components. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Connector Type** | M8 Circular | | **Number of Pins** | 4-Pin | | **Gender** | Receptacle / Female (Typical for -R suffix) | | **Mounting Type** | PCB Mount (Through-hole or SMT) | | **Orientation** | Right-Angle (R) / Back-Lock (BL) | | **Coding** | A-Coded (Standard for Sensors) | | **Rated Voltage** | 30V - 60V AC/DC | | **Rated Current** | 3A - 4A per contact | | **Ingress Protection** | IP67 (When mated) | --- ### 2. Functional Component Breakdown #### A. Contact Pins (The Electronic Interface) * **Material:** Usually made of Copper Alloy with Gold (Au) plating. * **Purpose:** Gold plating ensures low contact resistance and prevents oxidation in harsh industrial environments. * **Layout:** 4-pin configuration follows the standard industrial wiring for power (+), ground (-), and two signal lines (often NO/NC). #### B. The "Back-Lock" (BL) Mechanism * The **BL** designation indicates a **Back-Lock** Nut or mounting style. This is an electronic packaging feature that allows the connector to be secured to a panel or housing from the rear, ensuring a tight seal against dust and moisture. #### C. Termination Style * As a PCB-mounted part, it features solder tails. These are designed to be soldered directly onto a printed circuit board, acting as the bridge between the external cable and the internal circuitry of a device (like a PLC or Sensor Hub). --- ### 3. Application Use Cases 1. **Industrial Sensors:** Connecting Proximity, Photoelectric, or Ultrasonic sensors. 2. **Actuators:** Driving small solenoid valves or indicators. 3. **Robotics:** Used in "End-of-Arm" tooling where space is limited and small-form-factor connectors are required. 4. **Data Transmission:** A-coded M8 connectors are standard for basic I/O communication. --- ### 4. Circuit Diagram Representation In a standard 4-pin A-coded M8 configuration, the pinout typically follows this electronic convention: ```text Pin 1: Brown (+) 24V DC Pin 2: White (I/O Signal 2) Pin 3: Blue (-) 0V / GND Pin 4: Black (I/O Signal 1) ```
