September 29 to October 6 holiday, a total of 8 days, September 23 (Saturday), October 7 (Saturday), October 8 (Sunday), normal work.

Fuwei background suppress photoelectric, not afraid of color change, bright and concentrated spot, anti-sunlight interference, accurate and adjustable distance.

The optical path of the optical amplifier is guided by the optical fiber. The optical signal transmitted by the cast part is reflected, refracted and blocked by the measured object, and the light surface is changed. The light receiving part of the amplifier detects the change of the optical signal through the internal circuit conversion to generate the corresponding output signal, which has the characteristics of non-contact detection, diversity of detection methods and wide application scenarios.

Background suppression photoelectric sensor is a kind of sensor for object detection and positioning. It can detect only the presence and position of foreground objects by suppressing the interference of background light, and cannot detect objects beyond the set distance, so that the detection object can avoid background interference well.

Proximity Sensor is a sensor device used to detect objects approaching or approaching. It can perceive the existence of objects through different principles, such as electromagnetic induction, infrared, ultrasound, etc.
