Omron, E4C-UDA Series

last update: December 19, 2013

• 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.
