What Is the Compatible Masimo Red MNC SpO2 Adapter Cable?

The Masimo Red MNC compatible SpO2 adapter cable (IPR SKU SA-009RB-24) is an aftermarket replacement for Masimo 2642, a cable that allows Nellcor Oxismart-style SpO2 sensors to be used on monitors and defibrillators equipped with a 20-pin Masimo Red input. It is a compatible replacement, not an OEM Masimo product, built to match the fit, form, and function of the original. Facilities that stock Nellcor sensors can use this cable to run those sensors on Masimo SET-equipped devices, which simplifies sensor inventory across mixed fleets. At 7.9 ft (2.4 m), it provides more reach than the 3.9 ft (1.2 m) version, making it a better fit for bedside, ED, and procedural settings where the monitor sits farther from the patient.

Compatible Monitor Models

This compatible adapter cable works with the Physio-Control Lifepak 15 monitor/defibrillator and Masimo-equipped Zoll X Series units. It is also compatible with Masimo pulse oximeters including the Radical-7, Rad-5, Rad-5v, Rad-8, Rad-57, Rad-57c, Rad-57cm, Rad-57m, Rad-87, Rad-97, Pronto, and Pronto-7, as well as the Comen K12 Pro. Confirm that your device is configured for Masimo SET oximetry with a 20-pin Red input before ordering.

Design and Construction

The cable terminates in a 20-pin Masimo Red monitor connector on one end and a Nellcor-style 9-pin sensor connector on the other, so Nellcor Oxismart-compatible sensors plug in directly at the patient end. The 7.9 ft (2.4 m) length allows the cable to be routed along a bed rail or stretcher without placing tension on the sensor site. The cable is reusable and supplied one per bag.

When to Replace Your Red MNC SpO2 Adapter Cable

Adapter cables take repeated flexing, pulling, and cleaning, and the connector ends are typically the first point of failure. Replace the cable when you see intermittent “sensor off” or “no sensor” alarms that clear when the cable is moved, signal dropouts that persist after a new sensor is installed, cracked or loose connector housings, bent or recessed pins, or cuts and kinks in the jacket. If a known-good Nellcor sensor fails to read on a monitor that passes self-test, the adapter cable is the fastest item to rule out. Keeping a spare on hand minimizes downtime on critical monitoring channels.

Cross Reference and Interchange Part Numbers

This compatible cable cross-references to Masimo 2642 (Red MNC) and 2641 (Red MNC), and Physio-Control 11996-000366. Aftermarket interchange numbers include Datrend MCSA009RB24 and Unimed U708-87M. The OEM Red MNC cables are offered in 4 ft (2641) and 10 ft (2642) lengths and share the same 20-pin Red to Nellcor interface, so these references identify the connector configuration rather than the exact length. This listing is the 7.9 ft (2.4 m) compatible version.
