What Is the Compatible Masimo Pediatric Soft Tip SpO2 Sensor?

The compatible Masimo pediatric soft tip SpO2 sensor (IPR SKU SS-009RB-PS10) is a reusable finger sensor for pediatric patients on Masimo SET-equipped monitors and defibrillators. It is a compatible aftermarket replacement, not an OEM Masimo product, built to match the fit, form, and function of the original. The sensor uses a direct-connect design: its 3.3 ft (1.0 m) cable terminates in a 20-pin Masimo Red connector that plugs straight into the monitor, so no separate patient cable is required. This keeps setup simple and removes one connection point from the signal path.

Compatible Monitor Models

This compatible sensor works with Masimo pulse oximeters and Pulse CO-Oximeters including the Radical-7, Radical (20-pin), Rad-5, Rad-5v, Rad-8, Rad-57, Rad-57c, Rad-57cm, Rad-57m, Rad-87, Rad-97, Rad-97 NIBP, Rad-97 with NomoLine Capnography, Pronto, Pronto-7, and Pronto with Next Generation SpHb. It is also compatible with Masimo-equipped configurations of the Physio-Control Lifepak 15 monitor/defibrillator and the Zoll X Series, as well as the Comen K12 Pro. Confirm that your device has a 20-pin Masimo Red SpO2 input before ordering.

Design and Construction

The soft tip design wraps the patient’s finger without the spring pressure of a clip-style sensor, which improves comfort for children during extended monitoring and reduces movement-related dislodgement. The sensor is sized for pediatric patients weighing approximately 22 to 110 lbs (10 to 50 kg). Because it is reusable, the sensor can be cleaned and returned to service between patients according to your facility’s reprocessing protocol, which lowers per-patient cost compared to single-use adhesive sensors. Each sensor is supplied one per bag.

When to Replace Your Pediatric Soft Tip SpO2 Sensor

Reusable sensors wear with repeated cleaning and handling. Replace the sensor when you see torn, stretched, or hardened soft tip material that no longer holds the finger securely, discoloration or residue over the emitter or detector windows, cracked or loose connector housings, bent pins, or cuts and kinks in the cable. Persistent “sensor off” alarms, low signal quality, or readings that drop out when the cable is moved also indicate the sensor should be swapped. If a sensor fails to read on a monitor that passes self-test, try a known-good sensor first to isolate the problem quickly.

Cross Reference and Interchange Part Numbers

This compatible sensor cross-references to aftermarket interchange number Unimed U103S-87. It is designed as a direct-connect alternative for Masimo SET devices with a 20-pin Red sensor port. When matching to your existing stock, confirm the connector type, patient size, and soft tip style rather than relying on cable length alone.
