Optical sensors rely on the interaction between light and an object to measure certain physical properties, and offer advantages in terms of accuracy, speed and durability with applications from simple home automation to high-tech industrial use. The GRTE18S-F236Z photoelectric sensor is an example of an industrial optical sensor, where the application field and working principle will be discussed.

Photoelectric sensors are widely used in industrial control, mainly due to the wide selection of sensing range and measures, making them applicable for various tasks. The GRTE18S-F236Z benefits of a particular reflective sensing range of 4 mm to 6 mm, making it ideal for proximity sensing of objects in manufacturing, such as PCB boards, items to be measured, conveyed, sorted or controlled. Additionally, more complex operations may also be carried out with the sensor, such as counting, positioning and positioning control, which can be achieved through the integrated logic functions, providing ample versatility.

As far as the working principle, the GRTE18S-F236Z works by emitting a light source onto the object and measuring the reflected amount, providing a signal in response, which is related to the intensity of the reflection. When the reflected light reaches a certain value, an output is triggered from the sensor, indicating the presence of the object. Owing to this, it is possible to detect objects from a distance, as well as through a non-metallic barriers.

The output form of the GRTE18S-F236Z is an open collector type, meaning that a device that provides a current to the board is required in order to complete the circuit. Once completed, the current is then transported to the external device with the response of the sensor, so as to inform of the presence or absence of the object along with its proximal distance. It is in this manner that this particular photoelectric sensor is used for industrial applications, such as automated machines for the manufacture of electronics, textiles and plastics.

In conclusion, the GRTE18S-F236Z photoelectric sensor is a useful tool for industrial control thanks to its open collector output form, as well as its reflective sensing range. Its primary application is in automated machines for manufacture of items, but its versatility allows for more complex operations, such as counting, positioning and positioning control. With the added benefit of a non-metallic barrier detection, the GRTE18S-F236Z is certainly among the most reliable in its field.
