The H25 is the flagship of the BEI Sensors product line. It was designed from the ground

up for the industrial marketplace. The H25 offers features such as EMI shielding, 40 lb.

ABEC 7 bearings, matched thermal coefficients on critical components, and custom high-

efficiency optics. The encoder meets NEMA 4 and 13 requirements when ordered with

the shaft seal. Typical applications include machine control, process control, the wood

processing industry, oil well logging, industrial weighing, agricultural machinery, textile

equipment, web process control, robotics, and food processing.

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

). 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

). 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. 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.

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. 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
