The EE-SX870A belongs to the optical sensors – photointerrupters – slot type – logic output category. This device is optimized for close ranges, making it suitable for a variety of applications, such as the detection of small and thin objects.

The EE-SX870A utilizes a set of infrared light emitting diodes (LEDs) and phototransistors (PTs) to detect objects through a slot. When an object passes through the slot, the light-emission from the LED is blocked and the PT will detect the shutdown of the LED. This shutdown will signal the output, ATMega32, to change its logic level.

The EE-SX870A is widely used in various applications, such as the detection of thin or small objects, the presence of items such as flat or curved sheet surfaces, and paper and cardboard detection. In addition, it is used in fire prevention and automatic door applications.

The EE-SX870A has a built-in amplifier, a CMOS part IC, a set of three terminals – power supply, signal output and ground – and a detection distance of up to 20 mm. It is also equipped with a high-speed response time, up to 100 ms, and a wide operation temperature range, up to 80°C. Furthermore, the EE-SX870A is certified with UL and TUV.

To sum up, the EE-SX870A is a valuable device that features an amplifier, fast response time and high operability. Its applications are suitable for various scenarios such as the detection of small and thin objects, the presence of items such as flat or curved sheet surfaces, paper and cardboard detection as well as fire prevention and automatic door applications.
