HX-EP SERIES
DIGITAL OUTPUT

Utilizing an incremental encoder as the sensor, the 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.
The actual resolution of a HX-EP transducer differs from unit to unit because of tolerances associated with
the wire rope diameter and the capstan upon which the wire rope winds. The nylon jacketed wire rope option
will have the effect of slightly reducing the resolution. Linearity and repeatability remain independent of resolution. In applications where the output count is interpreted as a percentage of total travel, resolutional differences from
unit to unit are not critical. However, in applications where the digital output is to be interfaced to a digital display to give an output in
engineering units, the calibration constant supplied with the transducer may be used to calculate a suitable scale multiplier to produce the
correct engineering units. Alternative outputs shown in the Electrical Outputs table below are available to facilitate interfacing to a variety of different
types of equipment.

FOOTNOTES TO SPECIFICATIONS
1. t Supplemental Data section located at end of HX Series pages.
2. t The resolution shown is a calculated number based upon the capstan diameter, wire
tt rope diameter and line count of the encoding device. The tolerance on the resolution
tt accounts for resolutional differences from unit to unit due to manufacturing tolerances
tt on the capstan and wire rope. In practice, the output count in a given unit of travel is
ttan integer.
