Acceleration causes a spring and/or weight to either open or close a circuit depending on model.

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 12 direction when acceleration is applied. In the terminal 21 direction, the sensor will trigger

after the acceleration is removed (rebound effect). NOTE: If using the rebound trigger in the 21 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.
