Fujikura Oxygen Sensor Replacement

Looking for a Fujikura oxygen sensor replacement or a compatible Fujikura O₂ sensor alternative? 

Sensore offers proven, supported oxygen sensors designed for direct replacement with long-term availability and expert technical support. 

Sensore provides compatible replacements for Fujikura oxygen sensors. Our solution is built on the same proven sensing principle, ensuring comparable signal behavior, response characteristics, and system integration for existing Fujikura based designs.

Housed in a compact TO-8 package, the sensor features a slightly smaller form factor and is designed to fit the Fujikura mechanical footprint, allowing straightforward integration with minimal or no mechanical redesign. 

In addition to mechanical compatibility, Sensore O2 sensors for Fujikura replacements offer several performance advantages: 

• Fixed heater voltage 

• Improved sensitivity 

• Higher resolution at low oxygen concentrations
   

Full details of the technological and mechanical comparison are available in the Fujikura Cross-Reference Guide

Frequently Asked Questions 

Is this a direct replacement for Fujikura oxygen sensors? 

Our sensors are designed as compatible replacements for Fujikura oxygen sensors, using the same proven sensing technology and a TO-8 housing that fits the Fujikura mechanical footprint. Final suitability depends on the specific Fujikura model and application, which our specialists will confirm before recommendation. 

Does Sensore offer a replacement for the FUJIKURA FCX-UC, FUJIKURA FCX-UWC, or FUJIKURA FCX-ULL sensor part numbers? 

Yes. We can offer direct replacement for these Fujikura sensors. A full mechanical and technological comparison is available in our Fujikura Cross-Reference Guide, including footprint compatibility and key performance considerations.

Which Fujikura oxygen sensor replacement should I choose: SO-E2-xxx or SO-B0-xxx? 

SO-E2-xxx is optimized for applications with frequent heater power cycling, such as systems that power the sensor on and off multiple times per day. 

SO-B0-xxx offers slightly improved linearity, making it better suited to continuously powered systems requiring stable, consistent measurement. 

Our team can help you select the best option based on your operating profile. 

Will replacing a Fujikura oxygen sensor require system revalidation? 

Revalidation requirements depend on your internal procedures and regulatory environment. Because our sensors use the same sensing principle and comparable performance characteristics, many customers find the transition simpler than switching to a different measurement technology. We provide technical documentation to support evaluation and qualification. 

What are the typical lead times for Fujikura replacement oxygen sensors? 

Lead times depend on the sensor variant and order quantity. Standard products typically have short, predictable lead times, and our team can advise on availability for production planning or urgent replacement needs. 

Do you support OEMs transitioning from Fujikura oxygen sensors? 

Yes. We support OEMs and system integrators transitioning from Fujikura oxygen sensors with cross-reference guides, application guidance, and technical documentation. 

Is technical support available during and after the replacement process? 

Absolutely. We provide expert technical and application support throughout the replacement process, from sensor selection and evaluation to long-term operation and supply continuity.
