SQ-SEN-6XX ON/OFF TILT SENSOR On / off tilt sensing Normally open when vertical Normally closed when below or between the switch angles Non-sensitive to vibration or lateral movement when open FUNCTIONAL DIAGRAM 6XX SERIES SINGLE SIDED SQ-SEN-660, SQ-SEN-675 Simple Interface - No signal conditioning required Surface Mount - RoHS & REACH compliant, lead-free, Halogen free Made in USA - fully automated production, 100% testing, worldwide quality and price leader Zero-power Normally - < 50 nA when activated Activation Angle - Available in 60°, 75°, 45°, or 45° bidirectional Miniature Size - 3.3 mm x 6.9 mm Industrial Rated - 10 year life, -40º to 85º C Motion triggered wake-up GPS tracking, RFID, vehicle electronics Security, anti-tamper, anti-theft, alarms 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. The 6xx series is designed to be non-sensitive to vibration or lateral movement when vertical. 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 produce 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 as low as 50 nA.

SQ-SEN-6XX ON/OFF TILT SENSOR

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...
