Utilizing an incremental encoder as the sensor, the Unimeasure HX-EP Series Position Transducer provides a two channel square wave current sinking output signal in quadrature. The standard output is a single‑ended TTL compatible square. The resolution values shown in the specifications table indicate resolution for times 1 counting mode where a count is registered for one up transition in channel A. With interface electronics capable of times 2 or times 4 counting mode, a true resolutional increase of 2 or 4 may be obtained. For example, the HX-EP-50 has a resolution of approximately .004″ per count in times 1 counting mode whereas the resolution is approximately .001″ per count in times 4 counting mode.
