What Is the M1940A Compatible SpO2 Adapter Cable?

The IPR Medical SA-023-24 is a compatible aftermarket (not OEM) SpO2 adapter cable that replaces OEM part M1940A. At 7.9 ft (2.4 m), this reusable adapter pairs with sensors of the technology identified in the Specifications table.

Compatible Monitor Models

Compatibility for OEM part M1940A spans dozens of listed models, all collected in the Compatible Monitor Models table on the Specifications tab. Because several model numbers carry letter suffixes or are listed in combined form, match the exact number on your equipment label to the table before ordering.

Design and Construction

Intended for use with the sensor technology shown in the Specifications table, the SA-023-24 is a reusable adapter with a 7.9 ft (2.4 m) cable, packaged one per bag. Clean it between patients according to facility protocol, and look it over for wear each time it is reconnected.

When to Replace Your SpO2 Adapter Cable

An adapter that is due for replacement usually shows physical wear first: cracks or cuts along the jacket, kinks that will not relax, a damaged connector body, bent pins, or a strain relief that is coming loose. On the monitor, watch for intermittent SpO2 values, repeated sensor alarms, and readings that shift when the cable is bumped. A quick swap to a known-good adapter, with the same sensor still attached, confirms whether the cable needs replacing.

Cross Reference and Interchange Part Numbers

Order this compatible adapter in place of OEM part M1940A; OEM number M1940B cross-references to it as well. Further down the Specifications tab, the Cross Reference / Interchange Part Numbers table sorts the matching aftermarket numbers by brand.
