Optical sensors are widely used in multiple industries to detect various variations between objects or emission sources and their environment. The photoelectric, industrial HSE18L-N4A5AA optical sensor is a device composed of a light-emitting source, a light detector and a control circuit for interpreting detection results. It is designed to provide users with the convenience of detecting presence, absence or position of objects, as well as monitoring light intensity and color.

Photoelectric sensors are able to detect the presence of objects and also detect various other physical, electrical, magnetic, optical or chemical conditions. Being an example of this type of sensor, the HSE18L-N4A5AA features a light-barrier system composed of a matched emitter and detector pair - typically an LED and a photodiode - which provides an efficient infrared light barrier. It provides a reliable passage detection by means of reflecting or refracting the emitted beam up to a distance of 5 m.

The industrial HSE18L-N4A5AA sensor is also a hybrid electro-optical device which combines the advantages of an ultra-small mechanical relay and an LED indicator. This device features an ultra-small component (8.5 mm/0.255”) that can be equipped with an LED indicator and a built-in switching circuit which allows for fast response time (up to minimum 100 μs) during operation.

The working principle of the HSE18L-N4A5AA sensor is based on the concept of non-contact detection. The light-emitting source emits a beam of light while the device\'s light-detection unit, at the same time, detects reflected light or transmittance of the optical path. When the light-detection unit detects no reflecting light or transmittance of the optical path, the output of the light-detection unit triggers a "light detection signal" and enables the control circuit to output a signal to a connected processing device.

The HSE18L-N4A5AA sensor features two optical modes: Once-mode and Pulse-mode. In the Once-mode, the detecting distance for the sensor is determined by the reflected level of the optical path. This type of setting is suitable for shorter detection distances and constitutes a good fit for applications where a short sensing distance such as switch and distance measurement as well as color identification.

In the Pulse-mode, the detecting distance is determined by the output of the transistor. This type of setting is suitable for longer sensing distances, and is a good fit for applications such as intrusion detection, light barrier, and detection for far distance and vibration.

In terms of applications, the HSE18L-N4A5AA sensor is suitable for use in many industrial applications as it can detect objects accurately. Applications where this device can be applied include distance measurement, color identification, switch and presence detection, intrusion detection, light barrier, detection for far distance and vibration. This device is also very cost-efficient and can be used for both industrial as well as consumer applications, making it a great choice for multiple user options.

To conclude, the HSE18L-N4A5AA is a photoelectric sensor designed to provide users with the convenience of detecting presence, absence or position of objects, as well as monitoring light intensity and color. This device is based on the concept of non-contact detection and features two optical modes: Once-mode and Pulse-mode. It is suitable for a wide range of industrial and consumer applications, making it a great choice for all types of users.
