Masimo 4002 RD SET Inf Infant Adhesive SpO2 Sensor, 20/Box
The 4002 is the RD SET counterpart of the 2328 LNCS Inf: the same 3 to 20 kg sizing, with an RD connector for RD SET cables instead of an LNCS connector for LNC cables.78

| Monitors | LIFEPAK 35: Stryker's guide lists an RD SET adhesive, Inf, as 11171-000062 (see the Stryker row)12 LIFEPAK 15: Stryker's store files 11171-000062; the 02/2025 guide lists no RD SET adhesive sensor513 Zoll R Series, Zenix: Zoll 8000-001879; the R Series takes the 14-pin MD14-05 cable, the 4080414 |
| Stryker / Physio-Control Number | Stryker's online store lists 11171-000062 with the barcode FDA registers for the Masimo 4002. Masimo's 2025 cross-reference matches that number to the CS-2 version (4472). Match the Masimo number on your box, or send it to us.563 |
| Zoll Number | 8000-001879 (RD SET Inf, Infant SpO2 adhesive sensor, 20/Box), listed for the R Series and Zenix; Zoll does not print the Masimo number, so the match rests on the name and box size.4 |
| Replacement Tape | Masimo 4046, Replacement Tapes, Inf, the RD SET tape for the Inf size; ask us for the 4046.2 |
| Cross-Reference | See the Masimo 4002 row in the Masimo Part Number Cross-Reference |
Product Highlights:
- Two infant bands: From 3 to 10 kg the preferred site is the great toe (or the toe beside it, or the thumb); from 10 to 20 kg it is the middle or ring finger of the non-dominant hand.1
- RD connector: The sensor tab clicks into the cable with tactile and audible feedback, and only RD SET and RD rainbow SET cables take it; the LNCS Inf 2328 uses LNC cables.187
- Care limits: Not for patients allergic to foam rubber or adhesive tape, not under added tape, and not in an MRI environment.1
- Single patient use: Discard it after the infant, and reapply it to the same infant only while the windows are clear and the adhesive still grips.1

Frequently Asked Questions:
Which patient cable does the Masimo 4002 RD SET Inf plug into?
An RD SET or RD rainbow SET reusable cable. The 4072 and 4792 have the 20-pin monitor end, the 4798 the 25-pin right-angle end, and the 4080 the 14-pin end that Zoll sells for the R Series.8914 Push the sensor tab in, shiny contacts up, until it clicks.1
Does the Masimo 4002 fit the LIFEPAK 35, and which Stryker/Physio-Control number is it?
Stryker's LIFEPAK 35 guide lists an RD SET infant adhesive sensor, 20 per box, as 11171-000062.12 Masimo's 2025 cross-reference matches that number to the CS-2 version, the 4472, yet the barcode on Stryker's shop listing is the one FDA registers for the Masimo 4002.653
What is the Zoll number for the Masimo 4002, and does it fit a Zoll X Series?
The Zoll number is 8000-001879, Zoll's RD SET Inf, Infant SpO2 adhesive sensor, 20/Box.4 Its compatibility field reads R Series and Zenix, with no X Series entry, and Zoll prints no Masimo number, so the match rests on the name and the box of 20. For an X Series, Zoll's 3 ft Inf CS-3, the 4477, is 8000-000132.15
What weight is the Masimo 4002 for, and which digit does it go on?
It is for 3 to 20 kg. Up to 10 kg the great toe is preferred, with the toe beside it or the thumb as alternatives; from 10 to 20 kg use the middle or ring finger of the non-dominant hand, or a toe.1
Is the Masimo 4472 RD SET Inf CS-2 the same sensor as the 4002?
It has the same 3 to 20 kg range and sites, but the 4472 is the cabled version, with a 2 ft flat sensor cable that keeps the reusable patient cable away from the patient.1617
What is the difference between the 4002 RD SET Inf, the LNCS Inf 2328 and the M-LNCS Inf 2512?
Only the connector. The 4002 takes RD SET and RD rainbow SET cables, the 2328 takes LNC and Red LNC cables, and the 2512 takes M-LNC and rainbow RC cables.87
How do I put the Masimo 4002 on an infant's toe or thumb?
Run the cable along the top of the foot, set the detector on the fleshy pad of the great toe, and wrap so the emitter sits on the nail bed directly opposite it. The thumb or the toe beside it also works. Disconnect the sensor from the cable before moving it.1
Who should not use the Masimo 4002, and can it go back on the same infant?
Not for infants allergic to foam rubber or adhesive tape, and never in an MRI environment.1 It may go back on the same infant while the windows are clear and the adhesive grips; otherwise use a new sensor. Do not tape over it.
