2440-002 Datasheet, PDF (2/3 Pages) List of Unclassifed Manufacturers – TRIAXIAL ANALOG ACCELEROMETER MODULE

Model 2440 Triaxial Analog Accelerometer Module
SIGNAL DESCRIPTIONS
+VS (Power): Reddish brown wire. Apply +11 to +16 Volts
DC with respect to OUTPUT REF.
-VS (Power): Black wire. Apply -11 to -16 Volts DC with
respect to OUTPUT REF.
OUTPUT REF (Input): White wire. The X, Y & Z outputs
are referenced to this potential. This input is usually
tied to a potential halfway between the +VS and -VS
voltages. This input may also be used to offset the
output but the voltage difference between this input
and either supply voltage (+VS or -VS) must be greater
than or equal to 11V.
X, Y & Z (Outputs): Green, Light Brown & Light Blue wires
respectively. These output voltages are proportional
to acceleration; they increase with positive
acceleration and decrease with negative acceleration.
At zero acceleration the output is nominally equal to
zero volts with respect to OUTPUT REF.
PERFORMANCE - By Model: V_S=±12 to ±16VDC, T_C=25EC.
