The part number **756-1201/060-020** refers to a high-quality industrial sensor/actuator cable assembly manufactured by **WAGO**. This specific cable is designed for M12 connectivity, commonly used in automation, robotics, and sensor networks. --- ## Technical Specifications The following table breaks down the technical characteristics of the **756-1201/060-020**: | Feature | Specification | | :--- | :--- | | **Connector A** | M12 Plug (Straight) | | **Connector B** | Open-ended (Pigtail) | | **Coding** | A-coded (Standard for sensors/DC power) | | **Number of Poles** | 5-pole | | **Cable Length** | 2.0 meters | | **Jacket Material** | PUR (Polyurethane) - Halogen-free | | **Protection Class** | IP67 (Dust tight, waterproof) | | **Rated Voltage** | 250 V | | **Rated Current** | 4 A | --- ## Component Breakdown ### 1. The M12 Connector The "1201" portion of the code signifies a **straight M12 male connector**. M12 is the global standard for industrial Ethernet and sensor I/O due to its rugged screw-locking mechanism which prevents accidental disconnection in high-vibration environments. ### 2. PUR Cable Jacket (`/060`) The cable uses a **PUR (Polyurethane)** jacket. Compared to standard PVC, PUR offers: * **Flexibility:** High resistance to mechanical stress and bending. * **Chemical Resistance:** Excellent resistance to oils, coolants, and synthetic lubricants. * **Durability:** High abrasion resistance, making it suitable for drag chains or moving machine parts. ### 3. Length and Configuration (`-020`) The suffix `-020` denotes a length of **2.0 meters**. The "Open-ended" side allows technicians to wire the cable directly into a terminal block (such as WAGO 221 or 750 series I/O modules) or a custom control box. --- ## Wiring Color Code (Standard A-Coding) Since this is a 5-pole A-coded cable, the internal wires typically follow the standard industrial color scheme: 1. **Brown:** L+ (Positive) 2. **White:** I/O Signal / NC 3. **Blue:** L- (Negative/Ground) 4. **Black:** Switching Signal 5. **Grey:** Functional Earth / Reference --- ## Applications * **Factory Automation:** Connecting proximity sensors, limit switches, and photoelectric sensors. * **Robotics:** Power and data transmission in articulated arms. * **Harsh Environments:** CNC machining centers where exposure to cutting oils is frequent.
