Winston Score History

The full picture

First Sensor AG is a German company that makes sensors — small electronic devices that detect things like light, pressure, and gas. Its products are used in medical equipment, industrial machines, and transportation systems. The company is a specialist sensor manufacturer listed in Germany and is now a subsidiary of TE Connectivity, a large global electronics company.

First Sensor earns money by selling sensor components and modules directly to manufacturers who build them into finished products. Most of its business is in Europe, particularly Germany, with some reach into other industrial markets globally. Its competitive position comes from deep technical expertise in custom sensor solutions, which makes it harder for customers to switch suppliers once a product is designed in. The main risk is that demand for its sensors is closely tied to industrial and medical equipment spending cycles, which can slow sharply during economic downturns.
