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. 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: Vout = Vin). 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 cur-
rent).
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.
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 cur-
rent is 120 mA typical. This replaces prior IC’s with designations of 3904, 7406,
3302, 681 and 689.
4. 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.
5. Extended temperature ratings are available in the following ranges: -40 to 70°C, -40
to 85°C. Some models can operate down to -55°C. Extended temperature ranges can
affect other performance factors. Consult with factory for more specific information.
SSI output provides effective synchronization in a closed-loop control system. A clock pulse train from a controller is used to clock out sensor data:
one bit of position data is transmitted to the controller per one clock pulse received by the sensor. The use of a differential driver permits reliable
transmission of data over long distances in environments that may be electrically noisy. The encoder utilizes a clock signal, provided by the user inter-
face, to time the data transmission. Receiving electronics must include an appropriate receiver as well as line terminating resistors.
Features : Synchronous transmission Transmission lengths to 1000 feet Accepts clock rates from 100 KHz to 1.8 MHz
Data Transmission Sequence
1. Output driver of the encoder is a MAX 491 transceiver in transmit mode. The
recommended receiver is a MAX 491 transceiver in receive mode.
2. Controller provides a series of pulses (or differential pulse pairs) on
the CLOCK input lines.
3. On the first HIGH-to-LOW CLOCK transition, the encoder latches its data
at the current position and prepares to transmit.
4. Controller reads data on the falling edge of the next 15 clock cycles.
5. The first bit is a START bit and is always HIGH.
6. Next comes 13 data bits beginning with the most significant bit (MSB)
and ending with the parity bit. On 12 bit encoders, bit 13 is LOW. When
parity is not ordered, parity is LOW.
7. After the last CLOCK HIGH-to-LOW transition, a minimum of 40 micro-
seconds must pass before the beginning of the next CLOCK series.
Interfacing Long Data Lines
Cable impedance can create a transmission delay, in effect, shifting the
phase relationship between the clock pulse and the data. If this phase shift
exceeds 180°, then the wrong bit position will be sampled by the receiver.
As a result, the maximum allowable clock frequency is a function of the
cable length. For 24 AWG, stranded, 3 pair cable (BEI part number 37048-
003 or equivalent) the group delay is 1.36ns/ft. The table below shows
the maximum transmission rate allowable as a function of cable length to
ensure a phase shift of less than 90°.

SPECIFICATION ADDENDUM, Serial Synchronous Interface SSI):
SSI output provides effective synchronization in a closed-loop control system. A clock
pulse train from a controller is used to shift out sensor data: one bit of position data is
transmitted to the controller per clock pulse received by the sensor. The use of a
differential driver permits reliable transmission of data over long distances in
environments that may be electrically noisy. The encoder utilizes a clock signal,
provided by the user interface, to time the data transmission. Receiving electronics must
include an appropriate receiver as well as line terminating resistors. An optional parity
bit is available to validate the transmitted data.
Features:
Synchronous transmission
RS422/485 compatible
Transmission lengths to 1000 feet
Accepts clock rates from 100 KHz to 1.8 MHz
Parity bit option is available
Data Transmission
Sequence:
1. Data from the encoder is sent with a MAX 491 transceiver in transmit mode. It is
recommended to use any RS-422/485 compatible receiver and provide a termination resistor
based on the RS-422/485 specification for your specific voltage and DATA line length.
2. The CLOCK signals are RS-422/485 compatible, differential TTL, with 180 Ohm termination
resistors internal to the encoder. A series of pulses from the controller, on the CLOCK
lines, advances the data.
3. On the first HIGH-to-LOW CLOCK transition, the encoder latches its data at the current
position and prepares to transmit. The DATA signal during this transition is a START bit,
which is always HIGH.
4. The encoder shifts data to the DATA line on each LOW-to-HIGH clock transition, beginning
with the MSB. The controller reads data on the HIGH-to-LOW transiton of the next 12 clock
cycles ending with the LSB. The parity bit (if parity option is specified) is clocked out on
the 14th clock cycle. When the parity option is used, the 13th bit output is a logic LOW on
a 12 bit Encoder or the LSB of a 13 bit Encoder.
5. Parity is even. The sum of all data bits and the parity bit is even.
6. After the last CLOCK LOW-to-HIGH transition, a minimum of 30 microseconds must pass
before the beginning of the next CLOCK series.

Interfacing Long Data Lines:
Cable impedance creates a transmission delay, shifting the phase relationship between the clock pulse and the data. If this pulse shift exceeds 180 , then the wrong bit position will be sampled
by the receiver. The maximum allowable clock frequency, therefore, is a function of the cable
length. For 24 AWG, stranded, 3 pair cable (BEI part number 37048-003 or equivalent) the group
delay is 1.36nS/ft.The table below shows the maximum transmission rate allowable as a function
of cable length to ensure a phase shift of less than 90 .
CLOCK: Maximum (KHz) = 92,000/Cable Length (ft)
*Connector is a MS3102E18-1P, 10-pin connector on the encoder body and mates to an MS3106F18-1S connector or can be used with a standard cable/connector assembly, BEI P/N: 924-31186-18XX.
(XX = cable length in feet, ie. 10 = 10 feet)
Direction Control: Standard is CW for increasing count when viewed from the shaft end. Direction Control (Pin C) is normally HIGH (or N/C) and is pulled up internally to the positive supply voltage. To reverse the count direction,
Pin C must be pulled to LO (0V)

Direction of Count: Standard is CW increasing when
viewed from the shaft end. Pin R is normally HI (or N/C)
and is pulled up internally to +V. To reverse the count
direction, Pin R must be pulled LO (COMMON ).
Latch control: Encoder outputs are active and provide
continuous parallel position information when Pin
U is HI (or N/C). Pin U is pulled up internally to +V.
When Pin U is LO (COMMON) the encoder outputs
are latched at the logic state that is present when the
latch is applied and will stay latched until Pin U is no
longer grounded.
M18 Connector is a MS3102R18-1P, 10-pin connector
on the encoder body and mates to an MS3106F18-1S
connector or can be used with a standard cable/con-
nector assembly, BEI P/N 924-31186-18XX (Where XX
= 10, 20 30 or 50 for a 10, 20, 30, or 50 foot length).
This is the preferred connector for SSI output.
M14/19 Connector is a MS3112E14-19P, 19-pin
connector on the encoder body and mates to an
MS3116J14-19S or equivalent.
