Optical sensors are widely used in industrial and manufacturing applications, such as driving machines, controlling processes, and providing visual feedback and coordination. One type of optical sensor is the ZL2-N2421 is a high-accuracy photoelectric sensor for industrial applications.

The ZL2-N2421 is a two-wire type photoelectric sensor which has a wide detection range and a high level of sensitivity and resolution. Its detection range is from 1.5m to 13m, making it ideal for many industrial applications. It has an adjustable reflector, making it suitable for both reflective detection and transmissive detections. The accuracy of the sensor is ± 2mm.

The ZL2-N2421 can be used in a variety of industrial applications, including factory automation, material handling, woodworking, printing, and laboratory and medical processes. It is also used in automation of drive systems, machine tools, and flow control. In addition, the ZL2-N2421 can be used to detect and measure the presence, positioning, and size of objects.

The physical construction of the ZL2-N2421 includes a polypropylene housing, a precision no-contact detector, and a 4-grain photoelectric sensor. The internal circuitry comprises an LED diode, a photodiode, and an optical filter. The LED diode is connected to the power source in the photoelectric sensor, and the photodiode is connected to the output. The optical filter is used to reduce the amount of background light and to eliminate ghost signals.

The ZL2-N2421’s working principle is based on the measurement of distance between the reflector and the photoelectric sensor. The reflector is attached to the object whose position is to be detected. When light emitted from the LED passes through the reflector, it is reflected back to the photoelectric sensor. The photodiode measures the intensity of the light, which is then converted to a distance measurement. The output signal is then compared to a set threshold to indicate whether the object is detected or not.

The ZL2-N2421 is a reliable and accurate photoelectric sensor that is suitable for a variety of industrial applications. Its adjustable reflector and high level of sensitivity and resolution make it suitable for detecting and measuring the presence, positioning, and size of objects. The ZL2-N2421’s wide detection range and adjustable reflector make it suitable for both reflective detection and transmissive detection.
