Ultrasonic Proximity Sensor

E4B

Capable of Setting the Sensing Range
Using an Ultrasonic Beam
Ensures the stable detection of a variety of objects
regardless of the color, transparency, or material
(metallic or non-metallic) of the objects.
Limits the ultrasonic beam width to 8°, thus
detecting minute objects as small as 2 x 2 cm.
Detects objects smoothly while largely suppressing
interference from background objects.
Sealed to resist dust and dirt and emits ultrasonic
waves at a frequency of approximately 200 kHz,
thus providing high immunity from impact and
environmental noise.
