E2A Series

last update: December 19, 2013

• Ensures a sensing distance approximately 1.5 to 2 times larger than that of any conventional OMRON Sensor.

• Problems such as the collision of workpieces are eliminated.

• Full range of standard sizes (M8, M12, M18 and M30; both long and short barrels)

• Modular construction simplifies customization.
