EE-SX4239-P2

Photointerrupters are commonly used in automation applications where the need to detect the presence or absence of an object is necessary. EE-SX4239-P2 is a type of photointerrupter which belong to the slot type that has a logic output. This article provides an overview of its application field and working principle.

The EE-SX4239-P2 is an integrated optical sensor designed using the principle of reflectance. It consists of an infrared LED as the light source and a phototransistor as the detector. The signal emitted from the LED is reflected off the object passing through the slotted opening. It is then received by the phototransistor. When the reflected signal is sufficient enough, the photointerrupter will switch on the output. This allows the device to detect objects, regardless of the material or color.

The primary applications of EE-SX4239-P2 are switching and position detection. When used as a switch, it can detect the presence or absence of objects. It is ideal for use in assembly lines, robotic arms, and conveyors since it is capable of detecting a wide range of objects. In addition, it is also a suitable detector for paper, cardboard, and thick objects such as cans. As a position detector, the EE-SX4239-P2 is perfect for accurate positioning of moving parts. It can detect any change in the direction of the object, allowing precise and repeatable positioning.

The EE-SX4239-P2 has a simple yet effective working principle. The light emitted from the LED is received by the phototransistor. When the reflected signal is sufficient, the output changes from a low to a high level. This change in the output can be used to detect the presence or absence of an object. Additionally, the device also features a logic output which allows it to be used in different applications.

The EE-SX4239-P2 is an ideal choice for use in automation applications. It can detect a wide range of objects regardless of the material and color, making it a suitable choice for a variety of applications. It also features a simple yet effective working principle. With its logic output, the device can be used in different applications such as switching and position detection. Finally, it is capable of providing accurate and repeatable results for the detection of moving parts.
