Optical sensors have been used for a variety of applications, from factory automation to robotics, and have been widely accepted in the industry. The Photointerrupter Slot Type Transistor Output, or CNY29, is a compact and reliable optical sensor designed to sense the passage of a slot or notch through a reflector. It features a high speed response time of approximately 25 microseconds, making it suitable for many high speed applications.

The CNY29 photointerrupter is a three-terminal NPN transistor output type with a built-in high speed photo-transistor. It uses an LED and a phototransistor mounted in a single plastic housing. The LED is mounted in a black housing, and when activated will produce a beam of light which reflects off a slot or notch onto the phototransistor which is then activated, thus resulting in output from the transistor. The CNY29 is therefore suitable for sensing an object with a slot through it, or a reflecting surface behind a slot.

The CNY29 uses an integrated opto-element with a built-in phototransistor to detect the presence of a slot. This is done by the phototransistor detecting the reflected light from a slot when it passes through the opto-element. The amount of light detected is diverted to the transistor output, thus resulting in a switching action. When the slot passes through the optical element the transistor output switches from low to high.

The CNY29 is rated to operate up to 5V and can produce an output current of up to 200mA. It also has an optical wave length of 850nm, making it suitable for use in many applications. It is also highly efficient, consuming only 120mA of power. Furthermore, it is robust and highly reliable, with a life expectancy of 50,000 operations.

The CNY29 can be used in a wide range of applications, from factory automation to robotics, where its fast response time is highly beneficial. It is also widely applicable in the field of machine vision, where it can be used to detect objects in a 3D environment. It is also used in many other industrial applications such as automotive applications, packaging inspection, ultra-sonic sensing and more.

The CNY29 is also very easy to mount and operate. It requires a power supply of 5V and can be connected to the desired interface using just three wires. The wires should be connected with polarity as shown in the datasheet for correct operation. Furthermore, it is also RoHS certified and can be easily integrated with a wide range of application designs.

In summary, the CNY29 is an ideal optical sensor for its concise construction, high speed response time, and its ability to be integrated in a variety of applications. Due to its robust build and long life expectancy, it is a reliable and efficient solution for many factory automation and robotics projects.
