The **PD30CTDR10BPA2IO** is a high-performance photoelectric sensor manufactured by **Carlo Gavazzi**. It belongs to the "PointSpot" family and is characterized by its compact size and advanced **IO-Link** communication capabilities. --- ### 1. Key Technical Specifications Below are the primary electronic and physical parameters of the device: | Feature | Specification | | :--- | :--- | | **Sensor Type** | Photoelectric (Diffuse-reflective) | | **Sensing Distance** | Up to 1 meter (Adjustable) | | **Supply Voltage** | 10 - 30 VDC | | **Output Type** | Push-Pull (PNP/NPN) + IO-Link | | **Output Function** | NO or NC (Configurable) | | **Connection** | M8 Plug, 4-pin | | **Housing Material** | PBT (Polybutylene terephthalate) | | **IP Rating** | IP67 (Dust and water-resistant) | | **Light Source** | Infrared LED | --- ### 2. Electronic Component Features #### A. IO-Link Integration The "IO" suffix indicates that this sensor is IO-Link v1.1 compatible. This allows for: * **Remote Configuration:** Change sensing distance and logic (NO/NC) via software. * **Diagnostics:** Real-time monitoring of signal quality and internal temperature. * **Plug-and-Play:** Automatic parameter restoration when replacing a sensor. #### B. Diffuse-Reflective Principle (Background Suppression) The "DR" in the part number stands for **Diffuse-Reflective**. It operates by emitting infrared light and measuring the intensity of the light reflected back from an object. * **Precision:** It uses a high-performance ASIC that allows for consistent detection regardless of the object's color or surface texture. #### C. Push-Pull Output Circuitry Unlike traditional sensors that are strictly PNP or NPN, the **Push-Pull** output is universal. It can drive loads connected to either the positive or negative rail, making it highly compatible with various PLC input cards. --- ### 3. Wiring Diagram (M8 Connector) The pinout for the 4-pin M8 connector is standardized: | Pin Number | Color | Function | | :--- | :--- | :--- | | **1** | Brown | +VDC (Supply) | | **2** | White | Digital Output 2 (Customizable) | | **3** | Blue | GND (Negative) | | **4** | Black | Digital Output 1 / IO-Link Communication | --- ### 4. Application Areas * **Packaging:** Detecting the presence of boxes or containers on a conveyor. * **Material Handling:** Counting items or triggering robotic movements. * **Food & Beverage:** Due to the IP67 rating, it can handle environments with moisture and cleaning agents.
