Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Sensor Type** | Diffuse-reflective (Background Suppression) | | **Housing Material** | Stainless Steel (AISI 316L) | | **Sensing Distance** | 10 mm to 100 mm | | **Output Type** | Push-Pull (NPN/PNP compatible) | | **Communication** | IO-Link v1.1 | | **Protection Rating** | IP68, IP69K (High-pressure washdown) | | **Connection** | M8, 4-pin connector | | **Light Source** | Infrared LED (850 nm) | --- ### 2. Core Electronic Components & Technologies #### A. IO-Link Integration The "IO" suffix indicates that this sensor is **IO-Link enabled**. This allows for: * **Remote Configuration:** Sensitivity, timer functions, and logic can be adjusted via a PLC. * **Diagnostics:** Monitoring of sensor health, temperature, and operating hours. * **Process Data:** Real-time distance data and signal quality monitoring. #### B. Background Suppression (BGS) Unlike standard diffuse sensors, the electronics in this model use a specific geometric arrangement of the receiver elements. It can detect dark objects against a light background or ignore objects located just beyond the set sensing range. #### C. Push-Pull Output Circuitry The electronic output stage is **Push-Pull**, meaning: * It can function as both NPN and PNP without changing wiring. * It provides high immunity to electrical noise and can drive higher loads compared to standard open-collector outputs. #### D. Environmental Protection The internal electronics are fully encapsulated within a **Stainless Steel 316L housing**. This makes the sensor suitable for: * Food & Beverage applications (Ecolab certified). * High-pressure cleaning (IP69K). * Corrosive environments. --- ### 3. Pin Configuration (M8 Connector) | Pin # | Color | Function | Description | | :--- | :--- | :--- | :--- | | 1 | Brown | VCC | +10 to 30 VDC | | 2 | White | I/Q | Digital Input or Output (Configurable) | | 3 | Blue | GND | 0V | | 4 | Black | C/Q | IO-Link Communication or Digital Output | --- ### 4. Functional Applications * **Small Object Detection:** High precision for detecting components on conveyor belts. * **Washdown Zones:** Perfect for bottling plants or pharmaceutical production where harsh chemicals are used. * **Smart Factories:** Utilizing IO-Link data for predictive maintenance.
