The SleepSense Limb Movement Sensor (#1770) with Safety DIN Connectors is placed on the wrist or ankle and produces a signal that is directly proportional to the hand or leg movement. The internal Piezo film element converts every movement to a small analog voltage that provides a clear, reliable indication of that movement. The sensor may be connected to any AC (low level) channel on the recorder. Warranty: 1 Year - Free of Defects in Materials and Quality Workmanship.
