The gateway to 25 sensing specialists.

Amphenol Sensors is the sensor business of Amphenol Corporation — one of the world's largest designers and manufacturers of interconnect, antenna, and sensor systems.

Over decades, Amphenol has built its sensor portfolio through the careful acquisition of category-leading specialists: pressure pioneers like NovaSensor, temperature experts like Thermometrics and Telaire's CO₂ infrared technology, calibration leaders like Kaye, and many more.

Each brand keeps its own identity, engineering teams, and product roadmap. We don't dilute their expertise into a generic catalog — we let them stay best-in-class at the specific physical quantity they measure.

This site exists to point you to the right brand. Browse by what you need to measure, by your industry, or directly by brand. When you've found the right specialist, we'll send you straight to their team.
