Optical Sensors - Photointerrupters - Slot Type - Logic Output

The HOA6973-T51 is an Optical Sensors - Photointerrupter - Slot Type - Logic Output device produced by Sharp. It is designed for use in various settings, from consumer electronics like printers and DVD players to industrial automation systems. It uses light transmission through an IR LED to detect the presence or absence of an object in the sensing field. In its logic output configuration, the HOA6973-T51 can be used to detect and report the presence or absence of an object in a particular sensing area.

The sensor consists of an LED emitter and an optical receiver on either side of a small plastic slot. This slot allows light transmission from the emitter to the receiver when the object is present. When the object is absent, no light transmission can be detected. The sensor is designed to detect the presence of an object as a single logic input. The logic output can be on or off, depending on the presence of an object in the sensing field. This type of sensor configuration is suitable for detecting physical objects in a given sensing field, such as car sensors in a parking lot, door and window switches in home security systems, presence sensors in production lines, and more.

The HOA6973-T51 is easy to install and set up, and requires minimal wiring. Power is supplied by a single DC voltage, while the logic output can be configured for either open drain or push-pull logic. The operating temperature range is from -40°C to +85°C, making the sensor suitable for a wide range of applications. The emitter wavelength is 940nm, and the sensing distance is adjustable between 0.5-2mm. The system response time is 35μs, and the frequency response range is from 25-1500Hz. The device also has built-in over temperature protection.

The system can be set up in two different configurations. In the parallel operating configuration, the object will be detected as long as there is light transmission between the emitter and the receiver due to the attenuation of the object. This is useful for applications such as position sensing, gap detection, or presence detection. In the serial operating configuration, the object will only be detected when the light is completely blocked, making it suitable for applications such as slot detection or object counting. The system can be set up using jumper pins or via an external resistor, depending on the required application.

The HOA6973-T51 is a versatile and reliable system suitable for detection of physical objects in various applications. It is simple to install and set up, while providing accurate and reliable results. Its adjustable response time and temperature operation range make it suitable for a wide range of applications. With its features, it is the perfect choice for reliable object detection in various industries.
