Proximity and occupancy sensors play an essential role in several automation system capabilities. Compared to many other solutions, proximity/occupancy sensors are cost-effective and easy to use. The LHIRD0-N-IV manufactured by L3Harris Technologies is a combined proximity and occupancy sensor which can easily be integrated into automation systems for both industrial and commercial applications. This article provides an in-depth look at the LHIRD0-N-IV’s working principle and application field.

Application Field: The LHIRD0-N-IV offers numerous diverse applications. Automation systems use the device to detect objects within a certain range and adjust the operation or function accordingly. It is reliable and can detect objects within a range of 1-50cm. It is also suitable for use in harsh environments and can detect objects even in intense dust, smoke and fog. Additionally, the device is suitable for outdoor applications since it is waterproof and has UV resistant housing. The device also detects multiple objects which could be useful in applications where counting multiple objects are necessary.

Working Principle: The LHIRD0-N-IV is a combined proximity and occupancy sensor. It functions by utilizing a combination of low-frequency Radio Frequency (RF) signal reflection and infrared emitter detection. The device works by sending out low-frequency RF signals and detecting the reflections of those signals when it makes contact with an object. This allows the device to accurately detect the distance and size of the object. In addition, the device uses infrared emitters and a hidden optical receiver to ensure that when the object is too small for the signal reflection detection, the emission still allows for accurate detection. By utilizing both of these technologies, the device is able to accurately detect the distance and size of any object regardless of material or size.

Characteristic: The LHIRD0-N-IV offers numerous characteristics which makes it a great choice for integration into automation systems. It has a working temperature range of -30°C - +70°C, a response frequency of up to 200Hz, and a signal stability of 0.1%. Additionally, the device operates with a wide voltage range of 6-36 volts and can be easily integrated with control systems that use either analog or digital outputs and AC or DC outputs. The device also offers automatic calibration and multiple signal verification technologies for ensuring accurate detection.

Outputs: The LHIRD0-N-IV offers multiple outputs that can be utilized based on the type of application. It has two analog outputs; 0-10V DC for continuous precision of all threshold levels and 0-20mA DC for the sensing range status of the threshold levels. In addition, it has an open collector output which can be used for intermittent signal with 0.3ms pulse or continuous signal. It also offers an NPN/PNP output which is for both digital and analog signals.

In conclusion, the LHIRD0-N-IV combined proximity and occupancy sensors by L3Harris Technologies offer an efficient and reliable solution for multiple automation solutions. The device utilizes low-frequency RF signal reflection and infrared emitter detection to accurately detect the distance and size of any object. Additionally, the LHIRD0-N-IV is robust enough for harsh environmental conditions and equipped with adjustable threshold levels and multiple outputs for greater control. Furthermore, the device\'s easy integration and low cost make it an ideal solution for multiple industrial and commercial applications.
