for standard environments
Embody two seemingly contradictory characteristics: value-for-
money and high reliability
All 372 Models
F our 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: –25°C to 70°C
Water resistance: IP67
With an all-round 360° 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 360° 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 Connecto r Models)
have 4 LEDs at 90-degree int ervals,
which realize clear visibility from a
360-degree angle.
Oil-mist env ir onment resistan t!
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.
*1. There are so many kinds of E2E, not all IP69K rated. In detailed part#,
please contact your OMRON representative.

With the double distance, you can get
almost the same sensing distance with a
sensor that is one size smaller.

Ratings and Specifications
Note: 1. The response frequency is an average value. Measurement conditions are as follows: standard sensin g object, a distance of twice the standard sensing object
between sensing objects, and a setting distance of half the sensing distance.
2. When using any model of M8 size a t an ambient temperature between -25°C and 60°C, use a load current of 200 mA max., at an ambie nt temperature between
60°C and 70°C, use a load current of 100 mA max.
