E2A Cylindrical Proximity Sensor 1

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.

Please read and understand this catalog before purchasing

the products. Please consult your OMRON representative if

Precautions ■ Safety Precautions Wiring Power Supply Be sure to wire the E2A and load correctly, otherwise it may be damaged. Do not impose an excessive voltage on the E2A, otherwise it may be damaged. Do not impose AC current (100 to 240 VAC) on any DC model, otherwise it may be damaged. Load Short-circuit Do not short-circuit the load, or the E2A may be damaged.
PAGE 15
Wiring Maintenance and Inspection High-tension Lines Periodically perform the following checks to ensure stable operation of the Proximity Sensor over a long period of time. Wiring through Metal Conduit: If there is a power or high-tension line near the cable of the Proximity Sensor, wire the cable through an independent metal conduit to prevent against Proximity Sensor damage or malfunctioning. Cable Extension Standard cable length is less than 200 m. The tractive force is 50 N. 1.
