The PM-F65 is an optically isolated slot type logic output photo interrupter. This photo interrupter consists of a gallium arsenide infrared emitting diode (IRED) which operates in conjunction with a high gain integrated circuit (IC) to provide a high-speed, reliable, and highly sensitive response to the presence of a target object in a light path. An internal optical filter ensures high immunity to random ambient light.

The phototransistor and infrared diode are each optically isolated from the outside environment in an optically shielded 3 pin package which allows high noise immunity. This type of photo interrupter can be used in many applications which require an isolated output when a dark object passes through the photo interrupter’s light path.

The PMF-65 has a variety of applications. In industrial automation, the PM-F65 can be used to detect the presence or absence of a target object passing along an assembly line. When used in conjunction with a suitable light source, the PM-F65 can detect the presence or absence of an object moving at any given speed. The photo interrupter can also be used in automatic door openers, replacing switches and relays which lack the repeat-ability and speed of the PM-F65.

Another important application of the PM-F65 is in the device’s ability to detect objects or changes in pattern or color. When used with appropriate light sources, the PM-F65 can be used to recognize changes in pattern and color, allowing for the automatic sorting of goods or materials. This application is especially common in the food and beverage industry, where the photo interrupter can be used to identify and separate different types of bottles or cans.

The working principle of the PM-F65 is relatively simple. When an object passes in the light path, the photo-sensitive IC detects the change in light and produces an output signal that is electrically isolated from the outside environment. This output signal can then be used to trigger a control system.

The detector’s output can also be connected to an external circuit that can be configured to be either an analog or digital output, depending on the application. Additionally, the PM-F65 features temperature and voltage compensation which ensures reliable operation and long-term stability, even in extreme environmental conditions.

The PM-F65 is a reliable and robust photo interrupter, making it ideal for a variety of industrial applications where precise and reliable detection of changes in light patterns or color is required. Its simple and robust design, combined with its high noise immunity and temperature compensation make it an ideal choice for many industrial automation applications.

The PM-F65 has helped reduce the complexity of many industrial processes and has allowed industries to automate and control their processes more effectively. It is an important part of modern industrial automation and its many applications will continue to be critical to the success of industry for many years to come.
