Optical sensors are devices that are used to detect and monitor the presence of objects or light radiation emitted from sun, infrared, and other sources. Depending on the type of action, optical sensors are classified into such categories as photoelectric, industrial, medical, and consumer. FD-Z20HBW is a type of photoelectric optical sensor. It is commonly used in industrial applications and can be applied to monitor objects in motion with high precision.

Photoelectric sensors are mainly designed to measure a particular distance, usually in the range of an inch (2.5 cm) to hundreds of feet (up to 150 m). That is why FD-Z20HBW optical sensor is widely used in industrial, automotive, medical, and consumer applications for such purposes as level-crossing detection, object counting, speed sensing and measurement, and photoelectric switching.

The FD-Z20HBW optical sensor is an active photoelectric receiver composed of an emitter and an integrated circuit receiver. This type of sensor is designed to operate in operating environments with extreme temperatures ranging from -40ºC to 105ºC. Furthermore, the FD-Z20HBW optical sensor is capable of providing a detection range of up to 36 meters and adjustable time delays from 0.5 to 4.0 seconds, enabling it to detect even fast moving objects.

The working principle of the FD-Z20HBW optical sensor is based on the emission of a specific frequency light, generated by either an infrared LED diode or a laser diode. That light is then projected from the photoelectric sensor to a target. When the target object is within the range of the light beam, it is reflected back into the receiver, generating a voltage signal. Upon receiving the voltage signal, the receiver detects the presence of the target and triggers a general-purpose output/input signal, allowing it to be connected to any industrial control system, such as a PLC or a DCS.

The FD-Z20HBW optical sensor can be used in a variety of industrial applications, including process control, power control, and safety control. It is also suitable for use in hazardous areas and explosion-prone environments, as it is certified for SIL2/3 and CSA approvals. Furthermore, the FD-Z20HBW optical sensor is equipped with an adjustable on/off delay and adjustable hysteresis settings, thus providing reliable and repeatable results for even the most demanding industrial applications.

The FD-Z20HBW optical sensor is a versatile, robust, and reliable device designed to meet the diverse needs of today’s industry. Its ability to operate in harsh environments enables it to be used in a variety of industrial applications, making it the perfect solution for level-crossing detection, object counting, speed sensing and measurement, and photoelectric switching.
