E4B-LS70E4 Omron Ultrasonic Proximity Sensor NEW

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.
