Two Koyo light-duty incremental encoder product lines have been expanded and a higher resolution Koyo medium-duty absolute encoder has been added. The TRD-S Series of 6mm solid shaft and TRD-SH Series of 8mm hollow shaft incremental encoders now have 5-12 VDC open collector output versions in addition to the existing 12-24 VDC open collector or 5 VDC line driver output versions. These light-duty industrial grade incremental encoders have an IP40 environmental rating with resolutions available from 100 pulses per revolution to 2500 ppr and up to a 200 kHz maximum response frequency. Koyo light-duty incremental encoders start at $90.00. TRD-NA Series absolute encoders are now available in resolutions up to 2048 ppr. Starting at $271.00, these medium duty encoders feature a small 50mm diameter body and are splash proof IP65 rated.
