Powerful, slim, and quiet – ET25 provides automakers with more possibilities for ADAS applications. With only 25 mm thick, ET25 makes it ideal for both rooftop and behind-the-windshield installation. Its range can reach a stunning 250 meters without windshield, with the finest angular resolution reaching 0.05° x 0.05°. The sensor uses just 12 W of power to avoid overheating. At lower than 25 dB, its noise level is less than that of a quiet library,
