The **XS2G-D4S1** is a high-quality industrial connector manufactured by **Omron**. It is part of the XS2 series, specifically designed for M12 sensor and actuator connections. This part is a **field-assembly connector**, allowing technicians to wire cables manually in the field without specialized molding equipment. --- ### ## Technical Specifications The following table summarizes the primary electrical and mechanical characteristics of the XS2G-D4S1: | Feature | Specification | | :--- | :--- | | **Connector Type** | M12 Plug (Male) | | **Coding** | A-coded (Standard for sensors/actuators) | | **Number of Poles** | 4-pin | | **Termination Method** | Screw terminals | | **Rated Current** | 4 A | | **Rated Voltage** | 250 VDC / 250 VAC | | **Degree of Protection** | IP67 (Waterproof/Dustproof) | | **Contact Material** | Phosphor bronze / Nickel base, Gold plated | | **Cable Diameter** | 3 to 8 mm (adjustable via grommet) | --- ### ## Key Features and Components 1. **Solderless Termination**: The "S1" suffix indicates **screw terminals**. This allows for quick installation using only a screwdriver, making it ideal for repairs or custom cable lengths. 2. **Robust Housing**: The body is typically made of PBT (polybutylene terephthalate) resin, offering excellent insulation and resistance to chemicals. 3. **Waterproofing**: When properly tightened, the connector achieves an **IP67 rating**, meaning it can withstand immersion in water up to 1 meter for 30 minutes. 4. **Gold-Plated Contacts**: Ensures low contact resistance and prevents oxidation over long-term use in humid environments. --- ### ## Application Use Cases * **Industrial Automation**: Connecting proximity sensors, limit switches, and photoelectric sensors to PLC input modules. * **Robotics**: Routing power and signal lines through robotic arms where custom cable lengths are required. * **Factory Maintenance**: Replacing damaged molded M12 cables without needing to pull a completely new cable through conduits. --- ### ## Wiring Diagram (Standard A-Coding) The 4 pins follow the industry-standard M12 A-coded configuration: | Pin Number | Typical Function (DC) | Wire Color (Standard) | | :--- | :--- | :--- | | **1** | Brown | +VCC (24V) | | **2** | White | Secondary Signal / NC | | **3** | Blue | 0V / Ground | | **4** | Black | Primary Signal / NO | ---
