Optical sensors are devices that utilize light technology to detect the presence or absence of an object. Photointerrupters are a type of optical sensor that are activated when light is blocked by an object. These photointerrupters are typically used in applications that require sensing a gap in continuous media. Slot type photointerrupters, such as the HOA6971-T55, are generally used to detect the presence of paper and similar materials that travel in continuous or intermittent motion.

The HOA6971-T55 photointerrupter is a logic output slot type device with an internal LED and a phototransistor detector. The LED emits light which is then detected by the phototransistor. When an object passes through the slot the light is blocked and the phototransistor will supply a logic output. The HOA6971-T55 is designed to work in a wide range of applications including paper document detection in photocopiers, automatic credit card readers and automotive sensors.

The operational characteristics of the HOA6971-T55 are based on its internal components and design. The LED is powered by a constant current source and the phototransistor output is sensed by an output amplifier with hysteresis which is capable of detecting a minimum 1mm gap.

The HOA6971-T55 is designed to operate in a wide range of environments including temperature extremes from -40℃ to +85℃ and humidity levels of 5 to 95%. Additionally, it is designed with a built-in noise filter to reduce the effect of external interference on the output signal.

The HOA6971-T55 has an operating voltage range of 2.7 to 36 volts DC and an output current of 25mA. It is also capable of high-speed switching and has a high signal-to-noise ratio. As an added convenience, the device can be tested with a magnetic signal and is available in a variety of packaging options.

The HOA6971-T55 is an ideal solution for applications that require sensing a gap in continuous media. With its wide operating range and high signal-to-noise ratio, the device is suitable for a variety of industrial applications.
