ITR8104 is used in a wide range of fields for its reliable and accurate measurement of resistive element displacement and rotation. This Optical Sensor is an industry-leading slot-type photointerrupter with a transistor output. It combines a moving optical half-paddle wheel (Y) and a stationary photo-face plate (X) along the same axis. When motion occurs, the light produced by the internal LED is interrupted and the output transistor is actuated.

The photointerrupter\'s self-contained design and compact size are ideal for space restricted applications. The built-in locating pin ensures accurate assembly and repeatable positioning in rotary applications. The photointerrupter\'s high dynamic range accommodates a wide range of operating speeds, accommodating for very fast rotational movements and resistive element displacement over short distances. The maximum rated operating speed is 5000 RPM.

The ITR8104 is designed to provide a high level of resistance to dust, dirt, and shock, as well as a wide temperature range (-20 to +100 degrees Celsius) and a wide field of view up to 6mm. The photointerrupter also features a very narrow sensitivity slot of only 0.3 mm to ensure reliable detection of low-energy light transmission. The ITR8104 has a built-in feedback circuit that compensates for low output current. The feedback control loop allows stable operation even when the LED intensity is low.

The wide operating temperature range and narrow detection slot makes it suitable for applications such as medical digital imaging, inkjet printing, paper handling, barcode/ label printing, and positioning systems. This photointerrupter is also very popular for packaging and sorting applications due to its small size and low cost. The main advantages of ITR8104 are its ability to accurately detect low energy light transmission, its superior dust and shock resistance, its wide operating temperature range, and its built-in feedback circuit.

In applications where accuracy is key, the ITR8104 easily outperforms other photointerrupters. Its built-in feedback circuit and narrow sensitivity slot enable the photointerrupter to detect even low-energy light and it offers high accuracy and repeatability. The ITR8104 is the perfect choice for applications that require precise rotation and precise movement of resistive elements.
