Import Ds-100a Adult Finger Clip Spo2 Sensor — Buy in wholesale FOB from Supplier in China

The DS-100A adult finger clip SpO2 sensor is a reusable pulse oximetry sensor designed for compatibility with Nellcor monitoring systems including models N40, N100, N200, N290/5, N390, N3000, and N600. It features a durable plastic housing with a silicone finger clamp, a 1.5-meter cable with a 5-pin LEMO connector, and operates on a standard 2.5V to 5.5V input range. The sensor delivers SpO2 readings with an accuracy of ±2% within the 70% to 100% saturation range, and a pulse rate accuracy of ±2 bpm.

The sensor uses red and infrared LEDs with a photodiode detector to measure oxygen saturation, adhering to ISO 80601-2-61:2017 standards for pulse oximeter safety and performance. The finger clip is engineered for consistent pressure distribution, minimizing motion artifact interference. The outer casing is made from medical-grade ABS plastic, and the internal components are sealed against dust and light leakage. Typical industry sensors of this type use a single-use adhesive pad for pediatric models, but the DS-100A is designed for adult reuse, with cleanable surfaces suitable for disinfection with 70% isopropyl alcohol.

This sensor is purchased by hospitals in Southeast Asia, clinics in Latin America, and home care providers in Eastern Europe seeking cost-effective replacements for discontinued Nellcor sensors. Buyers typically order in batches of 100 to 500 units. Packaging is in individual polybags with a label showing lot number and expiry date, and cartons hold 50 units. Trade terms are FOB Shenzhen, with lead times of 7 to 14 days after payment confirmation. Certifications are not listed on the source data; buyers should request a copy of the CE or ISO 13485 declaration before shipment.
