BEI Sensors H20 User Manual

Model H20® Incremental Encoder

The H20 is an extremely rugged encoder designed to economically
fill the resolution range up to 4096 cycles per turn. This compact
unit features a shock resistant disc, heavy duty bearings, and EMI
shielding. The H20 conforms to NEMA 4 and 13 requirements. The
H20 is also available in a hub shaft style with a flexmount (inset) for
easy mounting directly to small motors. Typical applications of the
H20 include machine control, process control, agricultural machin­ery, textile equipment, robotics, food processing, and metering.

Special Models of the H20 Incremental Encoder are available with one or
more of the following certifications. Consult factory for details.

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 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
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
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. 5V/V. 5V/OC, 5V/OCR and 9V/OC can be intrinsically safe line
driver and open collector outputs available on certain model variations. They are intrinsi­cally safe only when installed per the controldrawing noted on the certification label
affixed to the encoder body.

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.
