Optical sensors are very popular and widely used electronic components that are capable of detecting electric signals when exposed to incoming light. The HOA1882-011 Photointerrupter Slot Type Transistor Output is one such sensor. It utilizes two infrared emitting diodes and two phototransistors in order to detect the presence of an object passing through a slot. The device has a built-in oscillator which, when triggered by the presence of light, produces a collector output voltage, thus allowing it to be used as a digital input for various digital systems.

Application field

The HOA1882-011 Photointerrupter Slot Type Transistor Output has a wide range of applications, ranging from presence sensing, detection of variations in light intensity or darkness, and object counting in assembly lines, to automation and control systems in production lines and motion detection in robots. It can also be used in devices such as motors, pumps, lifts and other similar automated equipment. It is highly reliable, and is capable of offering accurate and reliable sensing solutions with low power consumption.

Working principle

The HOA1882-011 Photointerrupter Slot Type Transistor Output utilizes two infrared transmitting LEDs which emit light that is received by two phototransistors. The phototransistors then convert the light to electrical signals. When an object passes through the slot, light from the LEDs is blocked, and the electrical signals decrease. The device contains an oscillator circuit that detects this decrease in electrical signal and produces a collector output voltage, which is sent to the digital control system as a digital input.

The HOA1882-011 Photointerrupter Slot Type Transistor Output is a highly-sensitive device that offers fast and consistent switching response. This makes it ideal for applications such as edge detection and movement detection. The device is available in various forms, such as an enclosed type with a nozzle, a surface mount type, and a plug-in type.

The HOA1882-011 Photointerrupter Slot Type Transistor Output is a reliable and cost-effective optical sensor that offers a variety of features and benefits. It is suitable for a wide range of applications, from motors to assembly lines, and can provide fast and accurate switching response with low power consumption.
