Cylindrical Proximity Sensor
E2A
Safe Mounting with Greater
Sensing Distance
• 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.
