The WFM120-120N321 is a slot type photointerrupter, featuring a transistor output, and is commonly used in a range of applications in the automotive, industrial and consumer segments. Photointerrupters are used to detect the presence of an object in an area, by utilizing light to interrupt a transmission.

The photointerrupter features a reflective optical slot, an infrared LED, and an integrated monitor photo transistor. When an object passes through the optical slot, the LED will emit infrared light, which will be blocked once the object is detected. This interruption will then be detected by the integrated monitor photo transistor, allowing the device to accurately sense an object, even from long distances.

The main components of the WFM120-120N321 include an optical slot, an LED, and a phototransistor. The LED emits an infrared light beam, and the phototransistor is used to detect the light beam’s intensity and amplitude. When an object interrupts the light beam, the light’s intensity and amplitude is reduced, triggering the phototransistor and generating a voltage signal. This data is then sent to a processor or microcontroller to be interpreted.

The WFM120-120N321 has a variety of applications in the automotive, industrial and consumer sectors. In the automotive sector, it can be used for applications such as brake light monitoring or airbag deployment detection. In the industrial sector, it can be used for machine vision applications, such as parts counting or alignment sensing. In the consumer sector, it can be used for applications such as home security systems, where the photointerrupter can be used to detect the presence of an intruder.

In conclusion, the WFM120-120N321 is an easy-to-use slot type photointerrupter, featuring a transistor output. It can be used in a variety of applications in the automotive, industrial and consumer sectors, and is ideal for applications such as brake light monitoring, airbag deployment detection, machine vision, parts counting, home security systems and more.
