Optical sensors are widely used in industrial automation. Among these sensors, OAS-61LD-2, also known as optoelectronic differential sensor, is a type of photoelectric sensor mainly used in industrial environment. In order for the application and working principle of OAS-61LD-2 be understood, the following paragraphs will discuss about its applications and working principle.

First of all, OAS-61LD-2 is suitable for the detection of various targets, such as metal and non-metal objects. It is often used in automation such as in production lines and robotic arms for positioning, part identification, and detection of rotational speed. Its application is very widespread and can even detect moving targets.

On the technical level, OAS-61LD-2 works by measuring the difference in light intensity which is created when a target is placed in between an emitter diode and two receiver diodes. When there is no target in between, the two receiver diodes receive the same light intensity from the diode, allowing the output signal to be measured as null. However, when a target is present, the two receiver diodes receive different intensity of light which used to be measured in order to calculate the differential signal. This differential signal is then used as the detecting signal of the sensor.

In addition, the OAS-61LD-2 has two optical receivers. These receivers are the differentiating element which allows the sensor to detect the target regardless of its opaque/translucent/transparent nature. The two receivers also allow the entire assembly to be resistant to ambient light and to be proof to oil or reflections. This ensures that the output signal of the sensor is free of external noise and is accurate.

On top of that, the OAS-61LD-2 also comes with an adjustable detection range which can be done through the regulators on its body. This allows the user to tune the sensor to be more sensitive or less sensitive, depending on their applications. Furthermore, the OAS-61LD-2 can operate as a normally open/normally open, allows for a wide range of uses in many different industrial applications.

In conclusion, OAS-61LD-2 is an optoelectronic differential sensor developed mainly for industrial purposes. It can be used to detect various targets, and it is also resistant to ambient light. Its operating principle involves measuring light intensity differences between the emitters and receivers, and it also comes with adjustable detection range. All these features combine to make the OAS-61LD-2 a very versatile and convenient sensor
