PM-R64 slot type photointerrupters are optical sensors that incorporate a light source and a photo detector into a single package. They are primarily used to detect the presence or absence of an object by sensing the interruption of a beam of light. The PM-R64 is a transistor output type photointerrupter that can detect a wider range of reflectance values. This makes them an ideal choice for applications such as automatic door operators and end-of-line detection for automated assembly lines.

The PM-R64 consists of an infrared LED and an NPN silicon phototransistor in a standard dip package. The LED operates at 940nm Peak outputs at a forward current of about 2.2mA. The phototransistor is sensitive to the light emitted by the LED. When the beam is blocked by an object, the current drops, which can indicate the presence or absence of the object.

The PM-R64 provides a reliable and cost-effective solution for applications that require low-cost, high-speed sensing. It is important to note that the LED in the PM-R64 can be thought of as a light source, which can be triggered by a number of external stimuli such as a magnetic field, electric field or the current pulse of a switch. This makes the PM-R64 an ideal choice for applications that require multiplexed sensing such as robotics.

In operation, the PM-R64 works by converting the light that is intercepted by the object into an electrical signal. When the light is blocked, the current in the phototransistor decreases, producing a voltage difference between the collector and emitter electrodes. The voltage difference can be detected by a signal detection circuit, which can then be used to trigger a response. This response can be anything from turning on a light to controlling a motor.

The PM-R64 is a versatile sensing device, with a wide range of applications. It can be used to detect the presence of objects such as cards, paper or people, and can also be used for counting objects or calculating speed. In addition, it can be used for end-of-line detection for automatic assembly lines and be used as a basic motion detection device. The PM-R64 has the advantage of being easy to install and highly reliable, making it suitable for industrial applications such as door openers.

Overall, the PM-R64 slot type photointerrupters are a reliable and cost-effective solution for a wide range of sensing applications. With its wide range of sensitivity, it can be used for a variety of applications, from counting and measuring the speed of objects to controlling motors and end-of-line detection. In addition, the PM-R64 is easy to install and highly reliable, making it an ideal choice for industrial applications.
