Withstands Harsh Environments Where the
Workpiece Can Rub against the Sensor
• Completely stainless-steel housing
• Long-distance detection equivalent to or greater than Proximity
Sensors with Resin Heads *1
• More than 20 times *2 the durability of Proximity Sensors with Resin Heads
• Spatter-resistant Models with fluororesin coating are available.
• Aluminum chip immunity
• Pre-wired Smartclick Connector Models are also available.
*1. The actual sensing distance will vary with the size or material of the object.
For details, refer to Engineering Data.
*2. Test results for stainless-steel brush rotating at 130 rpm.
Be sure to read Safety Precautions on page
4.
Note: Models with a fluororesin coating also use vinyl chloride for the cable material and
require separate protection.

Safety Precautions
(Unit: mm)
WARNING
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Item
Model
E2EF-(Q)X2D1
Never use this product with an AC power supply.
Otherwise, explosion may result.
E2EF-(Q)X3D1
E2EF-(Q)X7D1
Precautions for Safe Use
The following precautions must be observed to ensure safe operation.
1. Do not use the Sensor in an environment where inflammable or
explosive gas is present.
2. Do not attempt to disassemble, repair, or modify any Sensors.
3. Power Supply Voltage
Do not use a voltage that exceeds the rated operating voltage
range. Applying a voltage that is higher than the operating voltage
range may result in explosion or fire.
4. Incorrect Wiring
Be sure that the power supply polarity and other wiring is correct.
Incorrect wiring may cause explosion or fire.
5. Connection without a Load
If the power supply is connected directly without a load, the internal
elements may explode or burn. Be sure to insert a load when
connecting the power supply.

Note: The influence from other non-magnetic surrounding metals is nearly the
same as that from aluminum.
Mutual Interference
When installing two or more Sensors face-to-face or side-by-side,
ensure that the minimum distances given in the following table are
maintained.

Do not use the Sensor under ambient conditions that exceed the
ratings.
1. Do not use the Sensor in the following locations.
(1) Outdoor locations directly subject to sunlight, rain, snow, or
water droplets
(2) Locations subject to atmospheres with chemical vapors, in
particular solvents and acids
(3) Locations subject to corrosive gas
2. The Sensor may malfunction if used near ultrasonic cleaning
equipment, high-frequency equipment, transceivers, cellular
phones, inverters, or other devices that generate a high-frequency
electric field. Refer to the OMRON website (www.ia.omron.com/)
for typical measures.
3. Laying the Sensor wiring in the same conduit or duct as highvoltage wires or power lines may result in incorrect operation and
damage due to induction. Wire the Sensor using a separate
conduit or independent conduit.
4. Cleaning
Never use thinner or other solvents. Otherwise, the Sensor surface
may be dissolved.

Chips from Cutting Aluminum
Normally, chips from cutting aluminum will not cause a detection
signal to be output even if it adheres to or accumulates on the
detection surface. In the following cases, however, a detection signal
may be output. Remove the cutting chips in these cases.
