Optical Sensors are devices that detect the presence or absence of light. Photointerrupters are used in many Industrial applications, safety circuits, and medical devices to detect the presence or absence of a human body or object. The WF120-60B416 is an Optical Sensor of the Slot Type with Transistor Output. It is able to detect an object across a wide angle and can measure the distance up to 2mm.

The WF120-60B416 has a high sensitivity with withstanding current of 200mA and a fast response time. It is built in a compact size and has a long detection distance of up to 2mm. The most important feature of this photointerrupter is the slot structure, which allows detection of objects with different shapes. It is very suitable for applications which require detection of objects such as cylindrical, thin plate, and combined block.

The working principle of the device consists in the use of a light-emitting element and light sensor element which are arranged in specialized slots which are close to each other, such as an NPN type optocoupler. When the light-emitting element is turned on, light is emitted across the two elements. When an object or body passes between the two elements, the light beam is broken and the sensor sends voltage signal, whose amplitude is proportional to the amount of light blocked. This signal is interpreted by the connected microcontroller to determine if there is an object present.

The WF120-60B416 is used in a wide range of applications, from controlling factory production lines, home automation, to security systems. For example, it can be used in electric machines to detect the presence or absence of a person nearby and automatically stop the motor before the person is injured. It can also be used in home automation applications to switch on room lights when someone enters the dark room.

This device is an excellent choice for its versatile detection range, high response speed, long service life, and low costs. In conclusion, the WF120-60B416 optical sensor with transistor output is an ideal choice for a variety of applications.
