E3F PHOTOELECTRIC SENSORS
The quick way to install reliable and accurate sensing

By using the same optical sensing module you get
the same proven optical performance with minimum
tolerance variations and the highest durability.
So, with the new generation of photoelectric
sensors you get the highest reliability and best
price/performance available.
Omron’s new generation of photoelectric sensing modules
are at the heart of all next generation compact square and
M cylindrical photoelectric sensors.
Reliable sensing performance guaranteed!
Selling more than a million pieces per year,
Omron is a leading supplier of both M18
cylindrical and compact square photoelectric
sensors. Thanks to our ongoing commitment
to achieving the highest reliability, accuracy
and value for money, we have taken the
proven and ultra-reliable technology of the
E3Z photoelectric sensor and applied
it to the E3F family.

M18 plastic housing
Installation times can be significantly reduced with the EFZ.
The snap-in mechanism provides fast and vibration proof
mounting. The Laser welded compact M body measures
less than  mm in length and provides highest protection
and durability.
Minimize your installation costs
With Omron’s E3F family you need not worry about
lengthy installation times because the cylindrical shape
means that these sensors are quick to fit and align.
The customer benefit is clear: minimised installation
time and costs.
