DFRobot SEN0239 Infrared Proximity Sensor
Overview
The SEN0239 is an adjustable infrared proximity sensor featuring a cylindrical, threaded design for easy mounting in industrial and robotic enclosures. It operates on a wide supply voltage of 3V to 5V and provides a PNP-NO digital output when an object is detected within its 2-meter range. The sensor is shielded to minimize electromagnetic interference and comes pre-wired with a connector for rapid integration.
Why Choose This Part
This sensor excels due to its 200 cm sensing range and 3V-5V compatibility, making it directly interfaceable with both 3.3V and 5V microcontrollers without level shifting. The threaded M18 cylindrical housing allows for secure, adjustable mounting in panels or custom brackets, while the PNP-NO output ensures compatibility with standard industrial PLC inputs and logic controllers.
Applications
Key Specifications
Getting Started
Connect the 3-wire cable to your system by providing 3V to 5V DC power and monitoring the digital output pin. Use a microcontroller's external interrupt or a digital input with an internal pull-up/pull-down resistor to detect state changes. The sensing distance can typically be calibrated via a potentiometer on the back of the sensor housing to suit your specific environment.
