SmartSens Sen-XY: Where high performance meets low power.
Component
High-Resolution/Accuracy

SmartSens SEN-XY (AKA SEN-R)

The foundation of all of PNI's ready-to-integrate® sensor modules, SmartSens Sen-XY and Sen-Z sensors harness the existing power of the Earth's magnetic field to measure relative or absolute position in 2 or 3 dimensions. Small and RoHS compliant, they deliver best-in-class accuracy and resolution, temperature and noise stability, and dynamic range — while using less than 1/10 the power of ordinary sensors.

SmartSens sensors can be oriented in both the horizontal and vertical planes to construct a magnetometer with any number of measurement axes. Optimized for use in game controllers, solid-state navigation devices, and handheld devices with integrated compassing functions, they're ideal wherever power is at a premium and performance can't be compromised.
