Shock & Acceleration Sensor — SQ-ASD

The SQ-ASD series sensor is a normally open acceleration switch. 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.
