What Is the GE TS-E4-GE Compatible Ear Clip SpO2 Sensor?

The GE Healthcare TS-E4-GE compatible SpO2 sensor is a reusable, aftermarket adult ear clip pulse oximetry sensor for GE and Datex-Ohmeda monitors configured with TruSignal SpO2. It is a direct-connect sensor with a 9.8 ft (3.0 m) integrated cable, so no separate interconnect cable is needed. It is a compatible replacement, not an original GE part, and it is built to OEM fit, form, and function.

Compatible Monitor Models

This compatible sensor is confirmed for use with TruSignal-equipped GE CARESCAPE B125, B450, B650, B850, and V100 monitors, Dinamap B105M, B105P, B125M, B125P, and B155M monitors, and GE ProCare B20 and B40 monitors. It also fits GE Aisys and Aisys CS2 anesthesia systems and Datex-Ohmeda S/5 monitors, including the F-FM-00 and F-FML-00 frames and S/5 systems with E-series modules. GE monitors have been offered with TruSignal, Masimo, or Nellcor SpO2, and each requires matching sensors, so confirm your monitor’s SpO2 configuration before ordering.

Design and Construction

The adult ear clip attaches to the earlobe, giving clinicians a monitoring site when fingers are unavailable or poorly perfused, such as during surgery, with peripheral vasoconstriction, or when the hands must remain free for procedures. The 9.8 ft (3.0 m) cable provides reach from the patient to a bedside, anesthesia, or pole-mounted monitor. The sensor is reusable after cleaning and disinfection according to facility protocol and ships one per bag.

When to Replace Your GE TruSignal Ear Clip Sensor

Replace the sensor when the monitor reports “SpO2 sensor off,” “no probe,” or sensor fault messages, when readings are erratic or the pleth waveform is weak with good sensor placement, or when the clip spring has weakened, the pads are worn or cracked, or the cable jacket is damaged near the clip or connector. Ear clip sensors are handled and repositioned often, so keeping spares on anesthesia carts and critical care units helps prevent monitoring gaps.

Cross Reference and Interchange Part Numbers

This compatible TruSignal adult ear clip SpO2 sensor, IPR Medical SKU SS-016-AE30, cross-references to GE Healthcare / Datex-Ohmeda part numbers TS-E4-GE and TS-E2-GE, and interchanges with Praymed PSG0128-L and Unimed U910-121. The OEM sensors come in different cable lengths, about 13 ft for TS-E4-GE and 7 ft for TS-E2-GE, so confirm the 9.8 ft (3.0 m) length suits your setup. For a TruSignal interconnect cable, see the compatible GE TS-G3, IPR Medical SKU SA-016-24TS.
