Infrared emitting diode - SE2460/SE2470

1. Description of infrared emitting diode SE2460/SE2470:

Features of closed linear encoder:The light-emitting device, photoelectric conversion device, and linear scale are encapsulated in a sturdy profile. The light-emitting device uses an infrared emitting diode, and the photoelectric conversion device uses a phototransistor. The electrical connection wires enter the sensing head through a buffer circuit, and then are sent to the digital readout via an interference-proof cable to display displacement changes.
Optical encoderis a sensor that converts the mechanical geometric displacement of the output shaft into pulses or digital quantities through photoelectric conversion. When the motor rotates, the code disc rotates at the same speed as the motor. A detection device composed of electronic components such as light-emitting diodes outputs several pulse signals. By calculating the number of pulses output by the optical encoder per second, the current motor speed can be determined. In addition, to determine the direction of rotation, the code disc can also provide two pulse signals with a phase difference of 90°.
Infrared emitting diode SE2460/SE2470Typically used in linear encoders and encoders.
