Product Description:
Rectangular Ultrasonic Proximity Sensor with Built-in Amplifier
? Stable operation for a variety of objects regardless of color, transparency, or material (metallic or nonmetallic).
? Ultrasonic beam expansion of approx. 8 Detect small objects of 20 x 20 mm min.
? With reflective models, setting sensing zones ensures detection without influence by the background.
