Murata ultrasonic sensor

MA40H1S-R is the Murata 40kHz ultrasonic sensor perfect for human, gesture, object detection and distance measurement.

For its very small size, the Murata’s MA40H1S-R sensor can also be mounted in narrow spaces, making it particularly suitable in both lighting and industrial applications, such as burglar alarms, automatic doors or automotive parking assistance systems.
