Low oxygen level can put a strain on cell functioning including the heart and brain.  This is critical in acute medical situations like post-op recovery. TE Connectivity’s SpO2 optical components provide leading accuracy in oxygen level detection. With more than 27 years of proven reliability and expertise, TE Connectivity (TE) has designed SpO2 sensors with best-in-class flexibility to accommodate multiple wavelength options. Our ability to provide both components and complete sensor packages makes us a leading choice for pulse oximetry applications that require high degrees of precision, durability and performance. The EPM-4001 detector assembly uses a silicon planar diffused photodiode specially designed for medical applications. It features high efficiency and fast response. The EPM-4001 detector assembly is spectrally matched to emitter assemblies ELM-4001, ELM-4002 and ELM-4003.
