Omron E4B Ultrasonic Sensors
The E4B Ultrasonic Proximity sensor family packages low-profile size and multi-functionality with ease of use. This sensor ensures the stable detection of a variety of objects, regardless of color, transparency, or the material of the object. Reliability and accuracy of detection is attained by limiting the ultrasonic beam width to a narrow 8 degrees, allowing the user to detect smaller objects more consistently without detection interference from backgrounds. The E4B sensor is factory-sealed to protect against dust and dirt while shielded both mechanically and electrically from impact and electrical noise.
