Shock & Acceleration Sensor

Shock & Acceleration Sensor

The SQ-ASA series sensor is a normally closed acceleration switch. 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.
