SQ-SEN-6XX ON/OFF TILT SENSOR RoHS compliant, lead-free SMD package DESCRIPTION The SQ-SEN-6xx series acts like a position sensitive switch that is normally open when vertical and normally closed below or between the switch angles. It is designed to be non-sensitive to vibration in the vertical position. When at rest in a vertical position, the sensor will settle in an open state. When tipped down from vertical to the "switch angle" it will produce continuous on/off contact closures while in motion. When at rest below or between the switch angles, it will settle normally closed. The sensor can be used to produces CMOS or TTL pulses to interrupt (wake up) a microcontroller. Alternatively, these pulses can be counted to estimate the amount and duration of activity. The sensor is fully passive, requires no signal conditioning, and operates with currents a low as 0.25 μA.

SQ-SEN-6XX ON/OFF TILT SENSOR THEORY OF OPERATION The SQ-SEN-6xx series sensor acts like a position sensitive switch which is open or closed depending on orientation. When resting in a normally open orientation contacts are virtually guaranteed to be open. When resting in the normally closed orientation contacts are not guaranteed to be closed. A good rule of thumb is that they will be closed 95% - 99% of the time when at rest. When in a normally closed orientation vibration will cause the sensor to chatter open and closed. The engineer should design his or her software to look for...
