Constructed with a 4mm diameter solid shaft, the series offers resolutions from 100 to 1,024 pulses per revolution. 

The encoders are fitted with a two-meter cable with tinned ends and are available with either 5 to 12 or 12 to 24 VDC open-collector or 5 VDC line-driver outputs; the series provides up to 100 kHz response frequency. The TRD-MX series encoders start at $99 and are available for same-day shipping.
