Knock sensors are essential components that protect automotive engines from pre‑ignition damage. Mounted on the engine block or cylinder head, they detect high‑frequency vibrations caused by detonation or knocking and convert them into electrical signals for the engine control unit (ECU). This real‑

Proximity, position, and displacement measurements are essential in a wide range of industries—from valve control and level detection to safety systems, machine operation, and process automation. Modern magnetic sensors deliver the reliability and cost‑efficiency demanded by these applications. Rece

A flame sensor is a highly sensitive detector that monitors for the characteristic light emitted by combustion. Operating within the 760 nm to 1100 nm wavelength range, it can identify flames from a distance of up to 100 cm and with a detection angle of 600 °, making it ideal for safety‑critical app

Parking is a core skill for every driver, yet it can become a challenge—especially for newcomers or when space is limited. Traditional methods rely on mirrors and judgment, which can result in minor bumps or even larger collisions. Modern vehicles counteract these risks with parking sensors that del
