Philips SpO2 Sensor Technologies and Compatibility Guide
Philips patient monitors may use different SpO2 technologies, including Philips FAST, Masimo, Masimo SET, and Nellcor OxiMax. These technologies are not always interchangeable. For correct sensor selection, the monitor model, SpO2 module type, connector type, and sensor technology should be confirmed first.
This page lists general information about common Philips SpO2 sensor technologies in the maintenance and replacement market.
1. Philips FAST SpO2 Technology
Philips FAST SpO2 technology is widely used in many Philips and older HP/Agilent patient monitors. The typical connector is an 8-pin Philips-style connector.

2. Philips Masimo SpO2 Technology
Some Philips monitors use Masimo SpO2 modules. Older Philips Masimo modules may use Masimo sensors without SET technology. The connector is different from the Philips FAST connector.

3. Philips Masimo SET and Masimo Rainbow Modules
Later Philips modules may use Masimo SET technology. These modules may use a different connector and pinout from older Philips Masimo modules. Some newer modules use a 25-pin Masimo connector.

4. Philips Nellcor OxiMax SpO2 Module
Some Philips modules use Nellcor OxiMax sensors. The connector appearance may look similar to other SpO2 connectors, but the technology is different. For Nellcor OxiMax modules, there is usually a purple circle around the female port area.

5. Compatibility Notes
Philips FAST, Masimo, Masimo SET, and Nellcor OxiMax sensors are different SpO2 systems. A sensor should be selected according to the monitor model and SpO2 module type, not only by connector appearance.
- Confirm the patient monitor model.
- Confirm the SpO2 module type.
- Check the connector shape and pin count.
- Check whether the module uses Philips FAST, Masimo, Masimo SET, or Nellcor OxiMax technology.
- Confirm whether an adapter cable or extension cable is required.
6. General Sensor Condition Checks
SpO2 sensors may become defective after long-term use. Common damage areas include the sensor tip, cable wire, connector tail, and internal conductor. Long-term bending may break the inner conductor even when the outside cable jacket still appears normal.
If the sensor tip has no red light, the issue may be related to the LED emitter, cable, connector, extension cable, or module. If the red light is present but the reading is unstable, the issue may be related to the photodetector, cable condition, connector contact, sensor technology, or patient-side signal quality.
7. Replacement Information
Before selecting a replacement Philips SpO2 sensor, it is recommended to confirm the monitor model, module type, connector type, original sensor part number, or connector photo.
