Optical Sensors - Photointerrupters - Slot Type - Transistor Output

The EE-SX950-R is a slot-type photointerrupter with transistor output, designed and developed by 3M. It is a common type of optical sensor, which works by emitting a beam of light from one side when an object interrupts it. This type of photointerrupter, categorized as a slot-type due to its profile, transmits the signal using a transistor as a switch.

Application Fields

The EE-SX950-R is designed to offer a cost-effective solution for a wide range of applications. It can be used for low-frequency operation where an accurate and reliable sensing is needed, and is particularly suitable for applications involving automated moving mechanisms, such as robotics or conveyors. It can also be used for object detection where multiple slots are used to sense the presence of an object. Similarly, the photointerrupter can be used to detect the size or shape of an object.

Additionally, the EE-SX950-R can be used for machine and mechanical control applications, such as material conveyor belts, motors, printer feeding mechanisms, positioning systems, and so on. This type of photointerrupter can also be used to detect the presence of a human in a certain vicinity. Moreover, the EE-SX950-R can be used in applications such as gaming machines and vending machines to detect the presence of an object.

Working Principle

The working principle of the EE-SX950-R photointerrupter can be understood by considering an example. A simple circuit consisting of a lamp, LED, resistor, transistor, and EE-SX950-R sensor is connected in series to illustrate the process. When the EE-SX950-R is not in use, light from the lamp is reflected off the LED, and does not reach the phototransistor courtesy of the mirror-shaped pattern on the optical receptor surface of the EE-SX950-R. This means that the transistor is in its off state, and the connection between the lamp and LED is broken.

When an object passes in front of the EE-SX950-R, the light from the lamp is then able to pass through the slots on the EE-SX950-R and reach the phototransistor, which switches on. This causes the transistor to increase the connection between the lamp and LED, and the LED will then light up. The EE-SX950-R is able to detect the presence of a moving object in its vicinity, allowing it to be used in various applications.

Advantages

The EE-SX950-R photointerrupter has many advantages over other optical sensors. One of the most notable advantages is its low cost. Its small size and lightweight design also make it perfect for applications where space and weight are a concern. Furthermore, the EE-SX950-R has a high speed response time. It can detect movements as small as 1 mm tall, and can operate up to 500 kHz.

In addition, the EE-SX950-R is very reliable and offers long-term reliability. It has a long life expectancy of up to 1 million cycles, and a high-level-of-sensitivity due to its CDS imaging film. The EE-SX950-R also provides wide operating voltage range of up to 24 volts, making it ideal for a wide variety of applications.

Conclusion

The EE-SX950-R is a slot-type photointerrupter with a transistor output, with a wide range of applications ranging from robotic control mechanisms to object detection. Its small size and lightweight design make it easy to use and cost-effective, and its high speed response time and long life expectancy make it reliable and reliable for use in different applications. In short, it is a suitable and highly efficient optical sensor for many of today\'s applications.
