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 common excep-
tions 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 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 current).
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 cur-
rent). 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 of the 2008 BEI Specifying Guide.
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
* Products manufactured prior to April 2007 used the line driver IC number instead of voltage output in model number.
