### Overview of the OA2AS16-R100 The **OA2AS16-R100** is a specialized electronic component, typically categorized as a **Photoelectric Sensor** (specifically a retro-reflective or through-beam type depending on the specific series configuration) often used in industrial automation. --- ### Technical Specifications Below are the primary electronic and physical characteristics of this part: | Parameter | Specification | | :--- | :--- | | **Component Type** | Area Sensor / Light Grid | | **Detection Method** | Through-beam (Infrared) | | **Operating Voltage** | 12 - 24V DC | | **Sensing Range** | Up to 1000mm (1 meter) | | **Output Type** | PNP / NPN (Usually selectable or specific to model) | | **Number of Beams** | 16 Beams | | **Resolution/Pitch** | 10mm to 20mm (depending on beam spacing) | | **Response Time** | < 10ms | --- ### Core Electronic Components The internal architecture of the OA2AS16-R100 consists of several key stages: 1. **Emitter Array:** Consists of 16 Infrared (IR) LEDs. These are pulsed at a specific frequency to avoid interference from ambient light (like sunlight or overhead lamps). 2. **Receiver Array:** A matching set of 16 Phototransistors or Photodiodes. These detect the modulated IR light from the emitter. 3. **Signal Processing Unit:** An internal microcontroller (MCU) or ASIC that synchronizes the pulsing of the emitters and the scanning of the receivers. 4. **Output Circuitry:** * **Transistor Switch:** Uses a MOSFET or Bipolar Junction Transistor (BJT) to provide a digital signal (High/Low) to a PLC or controller. * **Protection:** Includes reverse polarity protection and short-circuit protection to prevent damage during installation. --- ### Wiring and Connectivity The device typically uses standard industrial M12 or M8 connectors. The wiring logic usually follows this pattern: ```yaml Pin 1: Brown -> +VDC (12-24V) Pin 2: White -> Logic Selection / Alarm Output Pin 3: Blue -> 0V (GND) Pin 4: Black -> Control Output (Switching Signal) ``` --- ### Applications * **Object Counting:** Detecting multiple items passing through a wide area. * **Presence Detection:** Ensuring a hand or tool is not in a dangerous zone. * **Web Guiding:** Monitoring the edge or alignment of materials in a manufacturing line. ---
