Optical Sensors - Photointerrupters - Slot Type - Transistor Output

Optical sensing technologies enable the detection of objects and materials without physical contact, using light energy and sensors to capture information. An optical sensor is a device that detects light and converts it into electronic signals, creating a measurement or indication of a change in a light intensity. Optical sensors are used in a variety of applications including aerospace, automotive, industrial, marine, medical, and other consumer applications.The ITR9808-F/T Photointerrupter is an example of an optical sensor used in applications where a slot type, transistor output is needed for current or digital signal acquisition. The Photointerrupter uses an infrared light-emitting diode (IRED) and an opposing light-sensitive transistor (LST) which are mounted and aligned facing each other across a slot opening. The IRED emits light which travels across the slot to the LST, and when an object passes between the IRED and LST the LST is triggered and a signal is emitted. The Photointerrupter is a versatile device with a wide range of uses including servomotor control, security code reading, machine tool safety, and sensing of slots and switches.The ITR9808-F/T is a transistor output Photointerrupter with a slot size of 8mm. It has a sensitivity of 0.5 lux and can sense objects up to 8mm distance from the slot. The ITR9808-F/T features a wide supply voltage range of 2.7 to 8.5V with a wide operating temperature range of -40℃ to +125℃. The output current is zero when the light is blocked and max when the light is unblocked. Each Photointerrupter is subjected to rigorous testing to guarantee consistent and reliable results.The working principle of the ITR9808-F/T is based on the optical sensing properties of infrared light. When an object passes between the IRED and the LST, the LST is triggered and a signal is emitted. This signal is then used by the external circuit for detecting the presence of an object and for various other applications such as servomotor control, security code reading, etc. The Photointerrupter is easy to use as it is equipped with built-in security features to ensure accurate and reliable results.The ITR9808-F/T offers superior performance and reliability in a variety of applications. It is a high-speed and low-cost optoelectronic component which can be used to detect the presence of an object and to gather information without making contact. The Photointerrupter is often used in industrial environments such as machine tool safety due to its robust construction and wide operating temperature range. Additionally, the Photointerrupter is used in a variety of consumer applications such as security code reading and reading of slots and switches. The ITR9808-F/T is a useful and reliable device which is easy to use and provides superior results in a variety of applications. By using infrared light and a sensor, optical sensing technologies can be used to detect objects and materials without physical contact. The ITR9808-F/T is a versatile device with a wide range of uses including servomotor control, security code reading, machine tool safety, and sensing of slots and switches. The Photointerrupter provides accurate and reliable results in an easy to use package.
