Omnidirectional tilt sensor SQ-SEN-815B series

digitalminiature

The SQ-SEN-815B Series, manufactured by SignalQuest, is a tilt sensor which acts like a position-sensitive switch that is traditionally open when horizontally positioned, whereas closed when below the switch-angle. Furthermore, these sensors are generally designed with a resistance against vibration in their horizontal positions. In instances wherein at rest in a horizontal orientation, this sensor will settle in an open state. On the other hand, when tipped from vertical to the switch angle, it will produce constant on-off contact closures while in motion. However, when at rest below the switch angle, it will settle conventionally closed.
