The NT-D35FZ is an optical sensor manufactured by the company Lipoo. It is designed to detect objects when the light beam is blocked or interrupted. It is used in a range of applications, such as motion detection, confirmation of material presence, and position detection.The NT-D35FZ has a long service life, as its optical components are sealed within an epoxy-filled, double-shell housing, offering excellent protection against dust, moisture, and shock. The sensitivity is adjustable for different size objects, and there is also an output delay function, which makes it suitable for a wide variety of scenarios. Additionally, the sensing distance is between 5 and 80mm, and the angle of detection is adjustable between 10 and 80 degrees.It is also compliant with the RoHS standards, which means that it does not contain harmful or hazardous materials that could have a negative impact on the environment. This makes it an excellent choice for applications that are looking to reduce their environmental footprint.
