SleepSense Inductive Interface Cables connect any SleepSense Inductive Belt to nearly any PSG system. Designed as plug and play replacements for Piezo Effort Sensors, SleepSense Inductive solutions are compliant with the new regulatory sleep center guidelines. The output of Inductive bands is exactly proportional to the cross section area of the band's closed loop around the body, changing as the patient breathes. Inductive Interface Cables measure these inductance changes to generate a reliable replication of respiration waveforms. Key Connector, 244cm length
