Ultrasonic Sensor E4C-UDA

Compact, Cylindrical Reflective Ultrasonic Sensor with Easy Setting


Feature :

Stable operation for a variety of objects regardless of color, transparency, or material (metallic or non-metallic).

Compact M18-sized cylindrical Head.
Product lineup includes Side-view Heads.

Check the sensing object distance and sensing position (i.e., threshold) on the digital display.

Easily make settings for workpiece presence/absence and elimination of background influence by using teaching.

Amplifiers include models with analog outputs.
