BEI Sensors HS22 Data Sheet

HS22 Incremental Optical Encoder

Specification No. 924-02068

The HS22 series

of hollow shaft

incremental encoder

offers application

advantages over

conventional optical

encoders. This

heavy duty unit

is designed

for ease of

installation to a servo

motor, the encoder’s flexible coupling

fits over the driven motor shaft to provide an accurate, backlash-free

method of attachment.

The mounting method eliminates the need for couplings, sprockets,

or gearing. The integral flex mount provides for a 20-degree angular

adjustment. Through-shaft or blind shaft configurations of the HS22

encoder are available.

Through-shaft units allow for applications where the center of the

encoder must be used for transmission of fluids, cabling, or optics.

Blind shaft units are designed to mate with shaft lengths of 0.50 to

1.50 inch. Standard outputs for both configurations incude: A and B in

quadrature with index and optional commutation signals for brushless

motor control.

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 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 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
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

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
ible 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 of the 2008 BEI Spec 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
