Proximity and occupancy sensors are commonly used in electronic automation and control systems to detect the presence and movement of objects in the vicinity. The LHUSD0-N-WH is a discrete device designed to detect the presence or lack of an object and energize an electrical circuit based on the results of the detection. This article will provide an overview of the application field and working principle of the LHUSD0-N-WH occupancy sensor.

Application Field and Working Environment of the LHUSD0-N-WH Sensor

The LHUSD0-N-WH is designed for use in industrial automation environments as a proximity or occupancy sensor. The device is designed to detect the presence or lack of an object in the sensing field, and energize an electrical circuit based on the detected presence/lack of an object. The beam range of the device is adjustable from 20 to 200 mm; the device is also designed to automatically adjust the beam width of the sensing field to adapt to the size of the detected object.

The device is designed for use in an environment with operating temperatures ranging from 0°C to +50°C, and the device should be shielded from exposure to moisture. The LHUSD0-N-WH is also designed for use in areas prone to high levels of Electro-Magnetic Interference (EMI). The device has an IP65-rated housing, and when used with a shielded wiring system, it provides reliable operation in environments with high levels of EMI.

Working Principle of the LHUSD0-N-WH Proximity/Occupancy Sensor

The LHUSD0-N-WH operates according to the principle of using an infrared beam to detect the presence or lack of an object in its sensing field. The sensor utilizes two infrared LED emitters and two light detectors to create a sensing beam. When an object enters the sensing area, the beam is interrupted and the device senses the obstruction. The device is designed to energize an electrical circuit when the beam is interrupted, and to de-energize the circuit when the beam is restored. This detection is repeated each time an object enters or leaves the sensing area.

The LHUSD0-N-WH is capable of detecting objects as small as 2 mm in size, and as large as its adjustable sensing range of 20 to 200 mm. The device is capable of detecting objects as far away as 200 mm. The device also features a built-in delay time in order to reduce false alarms due to rapid-cycling objects in the sensing field.

Conclusion

The LHUSD0-N-WH is a discrete device designed for use in industrial automation and control systems. The device is designed to detect the presence or lack of an object in its adjustable sensing field, and energize or de-energize an electrical circuit based on the results of the detection. The device operates according to the principle of using an infrared beam to detect the presence of an object, and is protected against exposure to moisture and Electro-Magnetic Interference, providing reliable operation in even the toughest environments.
