E2FM Additions to the Series
Highly Durable Proximity Sensor for
Tough Environments
■Completely stainless-steel housing
■Aluminum chip immunity
■Embedding installation to metal (steel) fittings
■Chemical resistance certified by Ecolab Europe
■Lineup includes pre-wire models and DC 3-wire NPN
output models with fluororesin coating.
Be sure to read Safety Precautions on
page 8.
Features
One-piece completely stainless-steel housing with a face thickness of 0.8 mm
The face thickness is approximately 4 times that of
previous models (E2ES) to enable sensing in even more
severe conditions than ever.
Brush Test Continuous Impact Test Chemical and Detergent Proof
0.8mm
The stainless-steel head
means almost no wear
when cleaned with a
metal brush.
E2FM E2EQ
(Spatter-resistant)
After 3 Minutes
E2ES E2FM
The E2ES with a
top wall thickness
of 0.2 mm was
penetrated after
10,000 impacts.
The E2FM was
not penetrated
after 250,000
impacts (depth:
0.26 mm).
More than 20 times the
durability of the E2ES!
The one-piece completely stainless-
steel housing of the sensing section
withstands the following chemicals
better.
•Sodium chloride
•Gasoline
•Dilute sodium hydroxide
•Dilute hydrochloric acid
•Mineral oil
•Barium hydroxide
Any many others
Note: Cannot be used for explosion-proof
applications.

Built-in Chip Immunity
Chip immunity performance has been provided to greatly reduce false
signals caused by spatter accumulation and other causes, almost
eliminating the needs for cleaning, e.g., with metal brushes.
Flush Mounting
