The M58 is a
rugged industrial grade
metric incremental encoder providing a unique combination of performance
and flexibility. The M58 features a wide range of resolutions, up to 80,000
cycles per turn. The robust design of the M58 provides it with excellent
resistance to shock and vibration. IP65 environmental protection level is stan-
dard (or IP67 is available with sealing flange). The M58 is an ideal replace-
ment encoder for metric equipment used in many industries in the US.
The M58 Incremental Encoder is available with the following certifications:
EN 55011 and EN 61000-6-2

Notes
1.Mounting
is usually done either using the D-style square flange mount, E- or G-
style servo mounts, or one of the standard face mounts, F1 for example. Consult
factory for additional face mount options.
2.The
shaft seal is recommended in virtually all installations. The most com-
mon exceptions are applications requiring a very low starting torque or those
requiring operation at both high temperature and high speed.
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 driv-
er outputs directly to circuit common/OV, which may damage the driver.
Unused outputs should be isolated and left floating. Our applications special-
ists would be pleased to discuss your system requirements and the compati-
bility 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 rec-
ommended 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 regu-
lated with 5V (TTL compatible) logic out. Supply lines are protected against
overvoltage to 60 volts and reverse voltage. Outputs are short circuit protect-
ed for one minute. Supply current is 90 mA typical (plus load current).
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.
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 volt-
age 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 des-
ignations 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.

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 spe-
cial 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.

Mating straight plug receptacles may be ordered from the factory:
For mating connector, order part number 924-81201-024
For 2 meter cable, order part number 924-31186-2302
For 10 meter cable, order part number 924-31186-2310
