Background Suppression Photoelectric Sensor (30~120mm)

This industrial-grade background suppression photoelectric sensor offers a robust solution for precise object detection, designed with an adjustable detection range from 30 to 120mm. With the ability to calibrate detection distance through a simple rotary knob, you can achieve accurate results tailored to your specific needs. Its fast response time of just 1ms ensures stable and reliable performance, making it ideal for applications where timing is crucial.

Constructed from durable ABS material, this sensor is built to withstand challenging environments while being environmentally friendly. It cleverly minimizes sensitivity to surface variations such as color or background interference, ensuring consistent detection even in complex scenarios. Additionally, integrated safety features like reverse polarity, over current, and over voltage protection enhance the security and operational safety of your setup.

With a versatile operating temperature range from -20°C to 55°C and a humidity tolerance of 35% to 85% RH, this sensor remains effective across diverse environmental conditions. It's especially beneficial for applications such as SMT pick-and-place machines, packaging material inspection, and industrial automation control. These features empower it to function optimally in security systems and various industrial settings where precision is paramount.

Before using the sensor, familiarize yourself with its operation and wiring. The factory default detection range is set at 30mm, indicated by a steady green LED. To adjust, align the sensor with your target and rotate the knob until the LED changes from green to red, signifying the optimal range setting. A built-in mode switch allows effortless toggling between Light-On and Dark-On modes, achieved by holding a button for 10 seconds until the LED confirms the switch.

For voltage measurement, remember to connect a 1kΩ resistor between the brown and black wires, measuring output between the blue and black wires. Follow these guidelines for smooth installation and maintenance. It is also crucial to safeguard the sensor from direct light exposure, avoid mirrored surfaces, and ensure the lens remains clean, particularly in dusty or oily environments. Though highly capable, the plastic housing is not impact-resistant—handle with care to preserve its integrity.
