The Nellcor DS100A adult hard-shell SpO2 sensor is a reusable finger-clip pulse oximetry probe built to the DS100A reference for Oxismart-technology patient monitors. It positions the emitter and detector over an adult fingertip to deliver continuous SpO2 and pulse-rate readings, connecting to the monitor through a 9-pin DB9 plug at the end of a 3.0-metre cable. This Nellcor DS100A Oxismart SpO2 sensor is supplied as new stock, giving hospitals, clinics, and biomedical suppliers a dependable, lower-cost option for adult finger-clip monitoring with extra cable reach.
Nellcor DS100A Adult SpO2 Sensor Built for Oxismart Monitors
Unlike newer OxiMax-only sensor lines, this probe is engineered for the earlier Oxismart sensor interface still running on many hospital and clinic monitors today. Confirm your monitor’s sensor port is Oxismart (non-OxiMax) before ordering, since Oxismart and OxiMax sensors are not interchangeable.
- Spring-loaded hard-shell clip holds the sensor in a stable position on an adult finger
- Reduces motion artefact and signal dropout during routine vitals checks
- Reusable housing lowers cost-per-patient compared with disposable sensors
- Longer 3.0m cable gives extra reach between the patient and the monitor
- Lightweight, low-profile clip comfortable for extended monitoring sessions
9-Pin DB9 Connector for Oxismart Sensor Ports
Connector Details
- 9-pin DB9 male connector, built to the Oxismart-mould sensor port pinout
- Secure pin engagement for a stable, consistent signal
- No adapter required on monitors using the Oxismart 9-pin interface
3.0m Cable: Extra Reach, Durable Build
Cable Benefits
- 3 metres (9.8ft) length – ideal for monitors positioned away from the bedside
- Durable cable jacket resists kinking and cracking from routine cleaning
- Lightweight cable construction reduces strain at the connector

Use Cases of Nellcor DS100A Adult
Hospital & Clinical Monitoring
Suited to wards, recovery rooms, and outpatient clinics that need continuous or spot-check adult SpO2 monitoring on Oxismart-supported monitors positioned further from the bedside.
Emergency & Transport Care
The extra 3.0m cable length and durable reusable build support repeated use in ambulance, emergency department, and transport monitoring settings.
Home & Long-Term Care Monitoring
A cost-effective reusable option for long-term home or aged-care SpO2 monitoring under clinical supervision.
Care & Maintenance
- Wipe the sensor housing and cable with a soft cloth dampened with a mild disinfectant between patients; do not immerse in liquid or autoclave.
- Inspect the clip spring and cable jacket regularly for cracks, kinks, or exposed wiring before each use.
- Store coiled loosely at room temperature, away from direct sunlight and sharp bends at the connector.
- Discontinue use and replace if readings become inconsistent or the housing is damaged.
Frequently Asked Questions
What monitors does Nellcor DS100A Adult Oxismart SpO2 sensor work with?
It’s built for monitors using the Oxismart 9-pin (DB9) sensor interface. Check your monitor’s sensor port before ordering, since Oxismart sensors do not plug into OxiMax-only ports.
Is this the same as the OxiMax DS100A sensor?
No. This is the Oxismart (non-OxiMax) version of the DS100A reference, supplied with a 3.0m cable. If your monitor uses OxiMax, see our Nellcor DS100A OxiMax SpO2 sensor instead.
Is this sensor new or refurbished?
It is supplied as new stock.
How long is the cable?
The cable measures 3 metres (approximately 9.8ft).
Can this sensor be reused on multiple patients?
Yes. It’s a reusable sensor for repeated clinical use following your facility’s standard cleaning and disinfection protocol between patients.
