Optical Sensors - Photointerrupters - Slot Type - Transistor Output

Optical sensors, such as the CNA1011K photointerrupter, are sensors that detect light to create an electric signal. This sensor is able to discriminate between light and dark, and has a slot type design that can detect an object’s presence. This detector has a transistor output for applications that require an electrical response.

What is the CNA1011K?

The CNA1011K is a dedicated slot type photointerrupter that uses a transmitted and received light to detect objects. This particular photointerrupter features a slot type design that extends the sensing range. Its features enable applications such as the sensing of gear tooths, machined parts, and barcodes.

The CNA1011K has a built-in amplifier and output transistor, and it works with a supply voltage of 5V. Unlike other photointerrupters, the CNA1011K requires very small drive current, which makes it ideal for applications that require a low driving current. It also has a wide sensing range, fast response time, and a wide range of operating temperatures.

The Working Principle of the CNA1011K

The CNA1011K photointerrupter operates with a transmitting and receiving infrared LED inside the same casing. The two beams cross in the middle of a slot that is made for the object to pass through without blocking both paths of light. It has a built-in amplifying circuit and a transistor output, providing an electrical response when the object is sensed.

When light is not obstructed, the infrared light is transmitted and then received again by the CNA1011K. This keeps the amplifier turned off and the output transistor is not energized. When an object of the desired operating height is detected, the amplified receives insufficient light and the output transistor will be energized. Thus, when an object passes through the slot, the output transistor will be energized providing an electrical response.

Applications of the CNA1011K

The CNA1011K is mainly used in industrial applications for detecting and counting. It is widely used for detecting gear tooths spacing, machined parts, paper-sheets and documents. When used in document detection applications, its low driving current and wide sensing range provide high sensitivity and accuracy. It is also used in gear tooth sensing applications as its fast response time enables it to detect and count gears more accurately.

In addition, the CNA1011K is also used for barcode detection as the narrow width and high distance accuracy allows it to accurately detect barcodes of different sizes and densities. This makes it ideal for barcode recognition applications.

Conclusion

The CNA1011K photointerrupter is an optical sensor that uses a dedicated slot type design, making it suitable for applications such as the sensing of gear teeth, machined parts, barcodes and documents. This photointerrupter has a built-in amplifier, transistor output and low driving current making it ideal for applications that require a low driving current. It also has a wide sensing range, fast response time and wide range of operating temperatures.
