Linearity
A Servo-Tek DC tachometer generator provides a Linearity at any speed is better than 0.1% of the
convenient and economical means of converting output at that RPM.

determined by output voltage polarity. Output (in
either direction) is held to a tolerance of 0.25% of
the average output.
Construction
Most of our DC tach generators are housed in
aluminum casings protected in accordance with
Mil-C-5541 or Mil-A-8625 or high performance
plastics. Alnico permanent magnets are used.
Armature shafts are stainless-steel, and rotate
on fully shielded stainless-steel ball bearings.
Commutators are manufactured from an alloy
containing at least 90% silver.
Armature
laminations are wound with Isomid insulated wire,
over Teflon slot insulation. The entire armature
is then baked, resulting in a NEMA Class H
insulation system.
SB-740A-2
Stability
Optimum brush and commutator combination
gives 0.1% stability. Highly stable output gives no
evidence of long-term drift.
Breakdown Voltage
Servo-Tek DC tachometer generators are factory
tested with an AC potential of 1250 volts RMS
applied for one second between (either) terminal
and shaft. E-Series units are tested with 500 volts.

Many
outstanding features make it particularly
suitable for use in all types of servo systems.
Although the diameter is only 0.760” the
E-Series provides up to 3 V/1000 RPM output.
The flange mounting arrangement provides a
convenient assembly method, and the sturdy
.187 shaft diameter permits the heavier loading
frequently encountered where pulleys or belt
drives are employed. The output bearing is fitted
with a seal to help prevent the contamination that
can occur in industrial applications.
Almost any Servo-Tek DC tachometer generator
can be manufactured with special configurations,
various electrical specs and shaft modifications
such as flats, pinions, holes, etc. Consult sales
department regarding your special requirements.
With output up to 50V/1000 RPM, D-Series
generators are ideal for applications where high
output voltages are required. Typically, these are
slow speed applications.

CS-7514F-51C and SA-7356F-1
SB-7483H-1
F-Series (1-8 volts/1000 RPM)
H-Series (5-16 volts/1000 RPM)
Servo-Tek low ripple DC tachometer generators
satisfy the need for a cost effective, very
low ripple tachometer. In addition to being the
first economical low ripple units of their type, the
F-Series tachometers incorporate all the desirable
features of the standard units such as temperature
compensation, long brush life, excellent linearity,
and small dimensions.
The H-Series DC tachometer generators are low
ripple units possessing all the same traits as the
F-Series, but with the B-length armature. This
means a slightly higher output voltage.
J-Series (16-30 volts/1000 RPM)
The J-Series DC tachometer generators are low
ripple units possessing all the same traits as the
F-Series, but with the D-length armature. These
generators are ideal for applications where high
outputvoltageswithlowripplesignalsarerequired.
The ripple voltage does not exceed 1.5% RMS
and 3.5% peak to peak at any speed in excess of
40 RPM on any F-Series, H-Series or J-Series DC
tachometer generator.
Other shaft sizes and mounting configurations are
available.

ST-13212 and ST-12970
Sealed Tachometer Generators
Ruggedized Tachometer Generators
Servo-Tek manufactures a complete line of sealed
units which are resistant against the harmful
effects of fluids. These units employ a one-piece
housing, a special shaft seal, and a form-fitted
rubber boot on the terminal end. Servo-Tek sealed
units meet electrical specifications after storage at
49ºC with 95% relative humidity for 24 hours.
These units are capable of enduring vibration
with amplitudes up to 0.03” total excursion at
frequencies from 4 Hz to 55 Hz in each of three
mutually perpendicular axes with no evidence of
physical damage. These units are available with a
low ripple output up to 30V/1000 RPM.
Servo-Tek ruggedized DC tachometer generators
are designed with sturdy aluminum housings and
strong mounting flanges. Other features offered
include extra-heavy armature shafts and bearings.
The mechanical flexibility of the ST-13212 allows
for the internal tachometer to be repaired or
replaced, without having to replace the expensive
anodized casting. The ST-13212 supplies outputs
from 2.6 to 50V/1000 RPM and runs at speeds
up to 5000 RPM. The shaft size is 5/16” in
diameter. The ST-12970 comes equipped with a
rubber coupling. It allows the unit to be driven
by a motor shaft with 0.167” wide slot. The
ST-12970 is also available with outputs up to
24V/1000 RPM and can run at high speeds.

end plate. Because the Servo-Tek overhung unit
is self-generating and provides an analog output,
it makes for an excellent alternative to the encoder.
No D-A conversion will be necessary! Mounts
easily using a 10-32 threaded shaft. No coupling or
mounting brackets will be required.
ST-7565A-2
Part Number: ST-7565A-2
Output Voltage: 7 VDC ± 5%, no load, per 1000 RPM at 25ºC
Internal Resistance: 270 Ohms typical at 25ºC
Ripple: 5% RMS of DC output voltage at speeds over 40 RPM
Linearity: 0.1% max., 0 to 4000 RPM
Bidirectional Output: 0.5% of nominal output in both CW and CCW directions
Polarity: Red wire positive with CCW rotation viewing shaft end
Temperature Coefficient: 0.05% per ºC of nominal output at 25ºC from -20ºC to 50ºC
