Cylindrical Proximity Sensor
E2B
Perfect fit
for standard environments
• Embody two seemingly contradictory characteristics: value-for-
money and high reliability
• All 372 Models
• Four different sizes: M8, M12, M18 and M30
• Single and double sensing distances, Shielded and unshielded
• A choice of short and long bodies, two connecting methods and four
output types
• Operating temperature: –25ºC to 70ºC
• Water resistance: IP67
• With an all-round 360º visible indicator

Features
Wide Variation
“Double Distance” Close at Hand
Perfect Fit to Your Application Needs
With no less than 372 models in the family.
You can choose the one that exactly meets your needs.
E2B series can save cost & your time via single source.

Reliable Performance
360-degree indication
Easy visibility for 360º even in
dark locations so you can mount
the sensor in any direction.
* The 360-degree indication is only for
Pre-wired Models of M12, M18, and
M30.
* The other models (Pre-wired Models
of M8 and all the Connector Models)
have 4 LEDs at 90-degree intervals,
which realize clear visibility from a
360-degree angle.

IP67
We have performed not only a specified
test for rating the degree of protection
(IP67) for catalogs, but also tests with oil mist which appears onsite.
Simulation tests has been performed with attachment of high
concentration of oil mist.

“Double distance” saves space and
reduces costs
With the double distance, you can get
almost the same sensing distance with a
sensor that is one size smaller.
