DESCRIPTION
The SQ-ASx series sensors act like
acceleration sensitive switches that open or
close when accelerated past an acceleration
threshold.
SQ-ASC series

microcontroller. The sensor is fully passive,
requires no signal conditioning, and operates
with zero current or only 50 nA depending on
model.

SQ-ASX SERIES
ON/OFF SHOCK AND ACCELERATION SENSOR
THEORY OF OPERATION
Acceleration causes a spring and/or weight to either open or close a circuit depending on model.
FUNCTIONAL BEHAVIOR
SQ-ASA
The SQ-ASA series sensor is a normally closed device. It is designed to be sensitive only in one direction. However, it will
exhibit some off axis sensitivity. Typical cross axis open signals are in the 2 – 8 mS range, where on axis open signals are
proportional to the duration of acceleration above the threshold.
SQ-ASB
The SQ-ASB series sensor is a normally closed device. It is designed to be sensitive in all directions. It is about 4 times
more sensitive off axis than on axis. Typical cross axis open signals are in the 2 – 8 mS range, where on axis open signals are
proportional to the duration of acceleration above the threshold. NOTE: If better accuracy is required, choose the cross axis
specification that matches your requirements and use two sensors at 90 degrees to one another, logically “OR’ed” together.
SQ-ASC
The SQ-ASC series sensor is a normally open device. It is designed to be sensitive only in one direction and is very immune
to cross axis acceleration. Only if a cross axis event is 10 times greater than the rated threshold may the sensor trigger in a
cross axis mode.
SQ-ASD
The SQ-ASD series sensor is a normally open device. It is designed to be sensitive in all directions. The sensor will trigger
radially or in the terminal 12 direction when acceleration is applied. In the terminal 21 direction, the sensor will trigger
after the acceleration is removed (rebound effect). NOTE: If using the rebound trigger in the 21 direction is not
appropriate for the application, mount two sensor parallel in opposite directions.
SQ-ASE
The SQ-ASE series sensor is a normally open device. It is designed to be sensitive in a radial direction. The sensor will
trigger radially when acceleration is applied. NOTE: To achieve an omnidirectional response mount two sensors at 90
degrees to one another in any plane, logically “OR’ed” together.
