HS25 Disc Resolutions
1. The typical hollow shaft product is supported by, and clamped to, the driving
shaft. A flexible tether is used to keep the housing from rotating.
2. The rubber shaft seal is recommended in virtually all installations. The most
common exceptions are applications requiring a very low starting torque or those
requiring operation at both high temperature and high speed. For these excep-
tions, a felt shaft seal is recommended. Felt seals require very low starting torque
and can virtually eliminate frictional heat. Encoders ordered with felt shaft seals
will have an enclosure rating of IP50 and will have less than 1/10th the Starting
Torque specified under Mechanical Configurations.
3. Non-standard index widths and multiple indices are available by special order. Consult
factory.
4. Complementary outputs are recommended for use with line driver type (source/sink)
outputs. When used with differential receivers, this combination provides a high degree
of noise immunity.
5. Output IC’s: Output IC’s are available as either Line Driver (LD) or NPN Open
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 replace-
ment 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).
15V/V: Multi-voltage Line Driver (4469*): 100 mA source/sink. Input voltage 5 to
15 VDC +/- 5% standard (Note: V
out
= V
in
). 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 90
mA typical (plus load current). This is a direct replacement for the 4469 Line
Driver.
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
current is 120 mA typical. This replaces prior IC’s with designations of 3904, 7406,
3302, 681 and 689. 5V/OCR, 15V/OCR, 24V/OCR: Open Collector (3904R*,
7406R*, 7273R*): Current sink of 70 mA max. Includes internal pull-ups sized
at approximately 100 ohms/volt. Max current source is 10 mA. Supply current
is 100 mA typical, 120 mA with internal pull-ups. The 5V/OCR, 15V/OCR and
24V/OCR are often replaced by the 28V/V in system upgrades.
3904, 3904R, 4469, 5V/V, 5V/OC, 5V/OCR, 9V/OC: Intrinsically safe line
driver and open collector outputs. These drivers are specific to intrinsically safe
encoders, and are installed per the appropriate control drawings listed in Table
2.1 on page 48.
6. 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.
7. Higher frequency response may be available. Please consult with the factory.
8. Extended temperature ratings are available in the following ranges:
-40 to 70°C, -40 to 85°C, –20 to 105°C and –40 to 105°C depending on
the particular model. Some models can operate down to -55°C. Extended
temperature ranges can affect other performance factors. Consult with factory
for more specific information.
9. Mating straight plug receptacles may be ordered from the factory:
For M12 use MS3116F12-10S, For M14 use MS3106F14S-6S
For M14/19 use MS3116J14-19S, For M16 use MS3106F16S-1S
For M18 use MS3106F18-1S, For M20 use MS3106F20-29S
