Omron E2FM DATASHEET
Inductive Proximity Sensor in full metal housing
E2FM
• Full body stainless steel housing for
highest mechanical protection
• Low frequency modulation for metal
chip immunity
• Flame retardant cable for high protection against welding spatter damage
Application
E2FM
Full body stainless steel housing with 0.8 mm thick sensing face protection
0.8 mm
Brush Test
Continuous Impact
Test
The stainless-steel
head shows minimal
wear when cleaned
with a metal brush.
More than 20 times
the durability of
standard sensors.
E2FM Standard sensor
Standard sensor E2FM
The standard sensor
with 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).
