The SQ-ASB series is a closed shock sensor device. The sensor is sensitive in all directions. The usual cross axis open signals are 2 to 8 mS. The axis open signals are proportional to the acceleration above the threshold. The sensor consist of an on/off shock and acceleration sensing. Make sure to select the cross axis specifications that matches the user's needs to achieve a better accuracy. The series is use on GPS tracking, RFID, vehicle electronics, security, anti-tamper, anti-theft and alarms.
