Optical Sensors - Photointerrupters - Slot Type - Transistor Output

WF120-95B416 is a type of optical sensor that can be used in a wide range of applications. These optical sensors are a type of photointerrupters, which have a slot-type design and a transistor (BJT) output. In their most basic form, photointerrupters are constructed using semiconductor parts, infrared emitters and detectors, and a mechanical interrupter. The most common applications of optical sensors like the WF120-95B416 are in the industrial automation, security, and transportation sectors.

When operated correctly, a slot-type optical sensor detects the presence or absence of an object in its sensing area. The infrared emitter and detector in the optical sensor are placed at an angle. When there is an appropriate object in the sensing area, the infrared beam is blocked, which tells the sensor to register the presence of an object. When the object is absent, the beam is not blocked and the output signal is low. The presence or absence of the object is thus determined.

The slot-type design of the optical sensor allows maximum object detection, since the angle of the emitter and detector permits the beam’s coverage area to be increased. The transistor output allows the signal to be transferred from the device. The signal is amplified at the output as current pulses directly connected to the gate of a transistor, which then switches on or off depending on the presence or absence of an object.

WF120-95B416 has a wide range of applications due to its precision and reliability. It is especially useful in situations where objects are moving fast or a high level of accuracy is required. Common applications for slot-type optical sensors include the detection of banknote presence in bank machines, alarm systems that detect an intruder, speed and distance measuring, detection of machine parts and parts passing through a process, and automatic door closing systems.

The WF120-95B416 optical sensor is highly durable and cost-effective. It is designed to operate reliably in the presence of high moisture, dust, dirt and other environmental conditions. Its low power consumption and fast response time further enhances its reliability in different types of applications. The WF120-95B416 is also easy to install and adjust.

In conclusion, the WF120-95B416 is a highly reliable optical sensor that can be used in various applications. It is a slot-type device with a transistor output and detects the presence or absence of an object in its sensing area. Its highly efficient design and easy installation make it an excellent choice for industrial automation, security, and transportation applications.
