DetailsRR28 series reflective encoder with PCBA and integrated housing design, with code disc, can output three channels of differential signals ranging from 500~16000CPR.
Z signal can be selected from 90°, 180° and 360°, without special instructions, the standard product is 90°.
RR282 series can output two channels of 1000-count differential signals.
This product is suitable for small size DC motor, stepping motor and servo motor.
RR28 series is available in a variety of options, as follows:


| Supply voltage | 3-5V | Supply voltage | 3-5V | |
| Maximum speed | 11000RPM | Maximum speed | 11000RPM | |
| Output Method | A、A/、B、B/、Z、Z/ | Output Method | A、A/、B、B/ | |
| Operating Temperature | -40 °C ~+85 °C | Operating Temperature | -40 °C ~+85 °C |
