Optical sensors are devices that convert optical signals such as light, infrared radiation or ultraviolet radiation into electrical signals. Photointerrupters are one type of optical sensor that is used to detect objects in a variety of applications, such as presence or absence detection, angular and linear displacement measurement, proximity sensing and object recognition. The HOA2004-001 optical sensor is a slot type photointerrupter module that consists of an infrared LED and a phototransistor, both encapsulated in a sealed polycarbonate package. The phototransistor is triggered when infrared light emitted by the LED is blocked or interrupted due to the presence of an object.

The HOA2004-001 optical sensor has a number of features that make it a suitable choice for applications such as object recognition, position detection and motion sensing. It has a slot width of 3.0mm and a minimum off-state optical transmission of 15%. It also has an on/off response time of 15 μs, a supply voltage of 5V to 12V and a maximum current of 10mA. In addition, it has a high noise immunity of 100 mV/m and a low leakage current of 2 μA. Furthermore, it is RoHS compliant and CE certified.

The working principle of the HOA2004-001 optical sensor is based on the transmission of light. The component consists of an infrared LED and a phototransistor. When an object interrupts the light beam between the LED and the phototransistor, the output signal of the phototransistor changes from high to low. This change in the phototransistor’s output is detected and used to control various devices and/or operate relays. The output of the phototransistor is a logic output, meaning that it can be used to control other logic devices or systems. The logic output can be used to control relays, motors, LEDs and any other type of load.

The HOA2004-001 optical sensor can be used in a wide range of applications including assembly lines, production lines, conveyor belts, home automation machines, traffic lights, etc. As it has a small size and low power requirements, it can be easily integrated into various systems where space and power are limited. It is also suitable for use in hazardous and explosive environments as it does not require contact with the target object.

In conclusion, the HOA2004-001 optical sensor is a slot type photointerrupter module with a logic output. It consists of an infrared LED and a phototransistor that can detect the presence of an object when its light beam is blocked. It has a small size and a wide operating voltage, making it suitable for use in various application fields. The sensor has a high noise immunity and a low leakage current, making it reliable and long lasting. It is suitable for use in hazardous and explosive environments and can be easily integrated into various systems.
