Often, the regulation of a circular motion is related to the registration of the direction and the speed of the rotation. Both can be determined with an optical encoder including LED, encoder disk, mask (reticle) and photodiode (PR5101). Beside photodiodes, amplifiers are also integrated into the chip to generate signals with high resolution, In addition to encoder ICs, also available at PREMA:
Printed circuit board (PCB)
encoder disk
mask/reticle
LED
Based on request, dimensions and resolution of the encoder disk are adapted. Additional functions are integrated into the receiver chip that afford an easy handling while mounting. Due to its compact dimensions, PR5202 can be utilized in mini-applications.
Applications:
automation technology
pumps
printer
household appliance (e.g. bread cutter)
motors

For higher flexibility at lower production volumes, PR5201 uses a reticle to adapt the photodiodes of the IC to customized resolutions and radii for A/B and Z channel. PR5201 includes a LED current control.
With two signals indicating the sense of rotation and a phase change on A and B, PR5201 provides an alternative method to count the angle of rotation of the encoder. These two signals are particularly suitable for further digital processing.

APPLICATIONS:

• incremental rotary encoders
• linear scales
• Chip-on-board or QFN package for flexible use for in a wide range of applications
• wide temperature range (-40°...125°C) for operation in rough environments
