## Technical Overview of the OBT150-R100-2EP1-IO The **OBT150-R100-2EP1-IO** is a high-performance diffuse mode photoelectric sensor manufactured by Pepperl+Fuchs. It is designed for industrial automation, featuring a compact R100 series housing and advanced digital communication capabilities via IO-Link. ### 1. Core Electrical Specifications The device operates on a standard DC power supply and features versatile switching outputs. | Feature | Specification | | :--- | :--- | | **Operating Voltage** | 10 ... 30 V DC | | **No-load Supply Current** | < 25 mA at 24 V supply | | **Output Type** | 2 push-pull (4 in 1) outputs, short-circuit protected | | **Switching Voltage** | max. 30 V DC | | **Switching Current** | max. 100 mA (resistive load) | | **Switching Frequency** | 1000 Hz | | **Response Time** | 0.5 ms | --- ### 2. Communication Interface (IO-Link) The "IO" in the model name signifies its integration with the IO-Link protocol, which allows for bidirectional communication. * **Interface Type:** IO-Link V1.1 * **Mode:** COM2 (38.4 kbit/s) * **Data Bit Width:** 2 bits (Process data) * **Functions:** * Remote parameterization (sensitivity, light/dark on). * Diagnostic data (operating hours, signal quality). * Device identification. --- ### 3. Optical Electronics The sensing technology relies on modulated visible red light to detect objects without a separate reflector. * **Light Source:** LED * **Light Type:** Modulated visible red light * **Detection Range:** 2 mm ... 150 mm (adjustable) * **Beam Diameter:** Approx. 10 mm at a distance of 150 mm * **Background Evaluation:** The sensor utilizes triangulation or energetic evaluation to distinguish targets from the background. --- ### 4. Connection and Wiring The sensor typically features an **M8 x 1 connector (4-pin)**. ```mermaid graph TD Pin1[Pin 1: L+ 10-30VDC] Pin2[Pin 2: Push-Pull Output 2] Pin3[Pin 3: L- Ground] Pin4[Pin 4: Push-Pull Output 1 / IO-Link] ``` --- ### 5. Control and Indicators The rear of the sensor contains physical interfaces for manual adjustment: * **Status LED (Yellow):** Indicates switching state (lights up when the object is detected). * **Power LED (Green):** Indicates power on/flashing for IO-Link communication. * **Potentiometer/Button:** Used for sensitivity adjustment (Teach-In) if not using IO-Link.
