The EE-SA102 is an optical sensor designed to detect the presence or absence of motion in the visible window of the device. The EE-SA102 is classified as a slot type, photointerrupter with a transistor output and is recommended for fast, reliable motion detection applications.

The EE-SA102 uses an infrared LED source and an infrared phototransistor detection cell as transducers for sensing. The LED source emits a continuous beam of light toward the detection cell which is activated when an object passes through the sensing slot. The output of the device delivers a signal once the beam is interrupted, indicating the presence of the object.

An important feature of the device is its small size and robust design, allowing for easy integration into a variety of mechanical systems and applications. The EE-SA102 also features a wide operating voltage range, enabling robust performance across multiple voltage settings. The device is also designed to withstand shock and vibration, reducing the risk of failed operation.

In terms of working principles, the EE-SA102 makes use of optoelectronic components and the laws of the photoelectric effect. When an object passes through the sensing slot, the infrared LED source is activated and emits a beam of light onto the detection cell. The infrared phototransistor detection cell receives the beam of light, which causes it to become more conductive and activate a transistor switch. The signal produced by the switch appears at the output of the device, indicating the presence of the object.

The EE-SA102 is an ideal solution for reliable detection of fast moving objects. It is well suited for use in industrial automation, material handling, robotics, and other motion detection applications. Furthermore, EE-SA102 offers the benefits of small size, wide operating voltage range, and shock and vibration resistance, which make it an attractive option for a variety of industrial and consumer applications.
