What Is the GE TS-SA4-GE Compatible Adult Soft Tip SpO2 Sensor?

The GE Healthcare TS-SA4-GE compatible SpO2 sensor is a reusable, aftermarket adult soft-tip finger 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 soft-tip design uses a flexible, one-piece sleeve that conforms to the finger, applying gentle, even pressure without a hinged clip. This makes it a good choice for longer-term continuous monitoring, restless patients, and patients where a rigid clip may cause discomfort or pressure points. The 9.8 ft (3.0 m) cable gives enough reach from the bedside or stretcher to a wall-, pole-, or anesthesia-mounted monitor without an extension. The sensor is reusable after cleaning and disinfection according to facility protocol and ships one per bag.

When to Replace Your GE TruSignal Soft Tip 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 on a well-perfused patient, or when the soft sleeve is torn, stretched, or no longer holds the finger snugly, or the cable jacket is damaged near the sensor or connector. Soft-tip sensors are cleaned frequently, so inspect the sleeve for wear and discoloration during routine checks.

Cross Reference and Interchange Part Numbers

This compatible TruSignal adult soft tip SpO2 sensor, IPR Medical SKU SS-016-AS30, cross-references to GE Healthcare / Datex-Ohmeda part number TS-SA4-GE, and interchanges with Praymed PSC0128-L and Unimed U410S-121. The OEM TS-SA4-GE has a longer cable, about 13 ft, so confirm the 9.8 ft (3.0 m) length suits your setup. IPR Medical also stocks the matching direct-connect TruSignal adult finger clip, GE TS-F4-GE (SKU SS-016-AF30), and ear clip, GE TS-E4-GE (SKU SS-016-AE30).
