Knock Sensor KS4-R 0261.231.218-U5G

Knock sensor KS4-R BOSCH 0261.231.218-U5G.

This sensor detects the structural vibrations of spark-ignition engines caused by uncontrolled combustion, ensuring precise monitoring even in extreme conditions. Its seismic mass moves with the vibrations of the engine block, generating a voltage signal via a piezoceramic element. This allows for directly defining the voltage thresholds corresponding to acceleration levels.

Main advantages: robust design, compact housing, and high-precision noise detection. Customizable with different cable lengths and connector options, this sensor adapts to the specific needs of each customer.
