Optical sensors detect changes in the environment and convert them into electrical signals. Photointerrupters, also known as slot type transistors, are one specific type of optical sensor. One such device is the HOA1889-011. It is designed for use in a wide range of applications and offers a number of advantages over traditional optical sensor technology.

The HOA1889-011 is an optoelectronic device which consists of an infrared light emitting diode (LED) and a photo-transistor detector. It is designed to detect the presence or absence of objects passing through the “slot” between the LED and the sensor. In operation, the LED emits a beam of infrared light which is detected by the photo-transistor. When an object passes through the slot the infrared beam is broken and the output of the photo-transistor is changed, thus indicating the presence of the object.

The design of the HOA1889-011 makes it both reliable and economical in comparison to other types of optical sensors. Its small size and low power requirement mean that it can be used in a variety of applications including the detection of small items on production lines and in safety and security systems. Its wide angular acceptance and fast response time also make it an ideal choice for use in proximity sensing applications.

The HOA1889-011 uses a transistor output rather than a contact output to sense the presence of an object. Its transistor output is activated when the slot is interrupted, and the output is turned off again once the interruption is cleared. The transistor output also allows for continuous sensing, since it is activated for as long as an object is present in the slot.

The device also offers flexibility when it comes to powering the LED and photo-transistor. In addition to being able to be powered from a standard 6V AC power supply, it can also operate on a 3 to 18V DC power supply, allowing for easy integration into existing systems. The device also features reverse polarity protection and an LED indicator for easy debugging.

The HOA1889-011 is an ideal choice for applications where reliability and cost-effectiveness are paramount. Its small size, low power consumption, and wide angular acceptance mean that it can be used in a variety of applications. The addition of the transistor output allows for continuous sensing and makes it an attractive choice for proximity sensing applications. With its reverse polarity protection and LED indicator, the HOA1889-011 is the ideal solution for a wide range of sensing needs.
