Model H25
®
Absolute Encoder
Long considered the industry standard for shafted incremental encoders, the Model H25
is now available in an absolute version with up to 13 Bits of resolution. It incorporates
many of the great standard features of the incremental version, including: EMI shield-
ing, 40-lb ABEC 7 bearings, matched thermal coefficients on critical components, and
custom optics. This encoder features a 12 or 13 Bit absolute parallel gray code output,
a selection line for count direction, and an output latch as standard. Output is standard
gray code with options for natural binary or SSI compatible signals. Signals can be pro-
vided in either a single-ended multi-voltage line driver (TTL compatible when provided
with 5 volts) or as an open-collector style of output. Typical applications include dam
gate control, cranes, telescopes, tool changers, and robotics.
