DESCRIPTION
ORDERING INFORMATION
The Model 2422 triaxial accelerometer module combines three orthogonally
mounted model 1210 integrated accelerometers in a rugged case for measuring
accelerations in commercial/industrial environments. It is tailored for zero to
medium frequency instrumentation applications. The anodized aluminum case
is epoxy sealed and is easily mounted via two #8 (or M4) screws. It is relatively
insensitive to temperature changes and gradients. An optional initial calibration
sheet (2422-CAL) and periodic calibration checking are also available.

OPERATION
The Model 2422 produces three differential analog
output voltage pairs (AON & AOP) which vary with
acceleration as shown in the figure (at right). The
outputs can be used in differential mode or single
ended, referenced to halfway between VDD and GND.
The output scale factor is ratiometric to the applied
VDD voltage and at zero acceleration, both AON & AOP
are equal to halfway between VDD and GND. The "Z"
axis is perpendicular to the bottom of the package,
with positive acceleration defined as a force pushing
on the bottom of the package. The "X" and "Y" axis
directions are marked on the cover with positive
acceleration defined as acceleration in the direction
of the axis arrow.

* NOTICE: Stresses above those listed under "Absolute

These are stress ratings only. Functional operation of the
device at or above these conditions is not implied. Exposure to
absolute maximum rating conditions for extended periods may
affect device reliability.
ESD CONSIDERATIONS: The model 2422 accelerometer is
a CMOS device subject to damage by large electrostatic
discharges. Diode protection is provided on the outputs but care
should be exercised during handling of the cable wire ends.
Individuals and tools should be grounded before coming in
contact with the cable wire ends .
PERFORMANCE - By Model: VDD=5.0VDC, TC=25EC.

Notes:
1. Voltages AOP & AON may exceed 0.5 volt above or below the supply voltage, provided the current into or out of the wire is limited to 1mA.
2. Single ended sensitivity is half of values shown.
3. Tighter tolerances are available on special order.
4. 100g versions and above are tested from -65 to +65g.

Model 2422 Analog Accelerometer Module
CABLE SPECIFICATION & LENGTH CONSIDERATIONS
The cable consists of seven 28 AWG (7x36) and one 26 AWG (7x34) tin plated copper wires. The seven smaller 28 AWG
wires are covered by 6.5 mils of Teflon FEP insulation. The larger single 26 AWG wire is covered by 9 mils of black Teflon
FEP insulation. The seven smaller gauge wires surround the single larger gauge (black) wire and the bundle is covered
by a 10 mil thick Teflon FEP jacket with a nominal outer diameter of 0.115”. We do not recommend extending the standard
1 meter cable cable length of the model 2422. If you decide to extend the cable length, we recommend you check each
individual installation for oscillation by tapping the accelerometer and watching the differential output for oscillation in the
20kHz to 50kHz region. If no oscillation is present then the cable length being used is OK for that particular device.
Different devices will tolerate different cable lengths.
