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.
The H25 Incremental Encoder is available with the following certification:

Standard is CW increasing when

and is pulled up internally to +V. To reverse the count
direction, Pin R must be pulled LO (COMMON ).
Latch control:
Encoder outputs are active and provide
continuous parallel position information when Pin
U is HI (or N/C). Pin U is pulled up internally to +V.
When Pin U is LO (COMMON) the encoder outputs
are latched at the logic state that is present when the
latch is applied and will stay latched until Pin U is no
longer grounded.

are available as either Line Driver (LD) or NPN Open
on a Ø 2.00 bolt circle.
Collector (OC) types. Open Collectors require pull-up resistors, resulting in higher
output source impedance (sink impedance is similar to that of line drivers). In
general, use of a Line Driver style output is recommended. Line Drivers source
or sink current and their lower impedance mean better noise immunity and faster
switching times.
Warning:
Do not connect any line driver outputs directly to circuit
common/OV, which may damage the driver. Unused outputs should be isolated and
left floating. Our applications specialists would be pleased to discuss your system
requirements and the compatibility of your receiving electronics with Line Driver type
outputs.
28V/V:
Multi-voltage Line Driver (7272*): 100 mA source/sink. Input voltage 5 to 28
VDC +/- 5% standard (Note: V
out
= V
in
). This driver is TTL compatible when used
with 5 volt supply. Supply lines are protected against overvoltage to 60 volts and
reverse voltage. Outputs are short circuit protected for one minute. Supply current is
120 mA typical (plus load current). This is the recommended replacement for 3904R
and 7406R open collector outputs with internal pullup resistors. It is also a direct
replacement for any 4469, 88C30, 8830 or 26LS31 line driver
28V/5:
Multi-voltage Line Driver (7272*): 100 mA source/sink. Input voltage 5 to 28
VDC +/- 5% standard, internally regulated with 5V (TTL compatible) logic out. Supply
lines are protected against overvoltage to 60 volts and reverse voltage. Outputs are
short circuit protected for one minute. Supply current is 90 mA typical (plus load cur-
rent).
Note:
Limit encoder load to 2.5W max at ambient. Example at 12 VDC: 2.5W/
(+12VDC minus +5VDC) = 357 mA total allowed current. Consult factory for your
specific requirements.
28V/OC:
NPN Open Collector (3904*, 7273*). Current sink of 80 mA max. Current
sourced by external pull- up resistor. Output can be pulled up to voltage other than
supply voltage (30 V max). Input voltage 5 to 28 VDC
+
/- 5% standard. Supply cur-
rent is 120 mA typical. This replaces prior IC’s with designations of 3904, 7406,
3302, 681 and 689.

Special –S at the end of the model number is used to define a variety of non-
standard features such as special shaft lengths, voltage options, or special testing.
Please consult the factory to discuss your special requirements.
5.
Extended temperature ratings are available in the following ranges: -40 to 70°C, -40
to 85°C. Some models can operate down to -55°C. Extended temperature ranges can
affect other performance factors. Consult with factory for more specific information.
* Products manufactured prior to April 2007 used the line driver IC number instead of voltage output in model number.
