Omron, E2EF Series

Long-distance Detection*1 Equivalent to or Greater Than Proximity Sensors with Resin Heads

Installation is possible at the same distance as Proximity Sensors with Resin Heads
The metal heads of the E2EF achieve the same distances for the same sizes as the E2E Proximity Sensors with Resin Heads.
This allows you to use Proximity Sensors that withstand friction with the workpiece without major changes to mounting brackets.

*1. The actual sensing distance will vary with the size or material of the object.
For details, refer to Engineering Data.

More than 20 times*2 the durability of Proximity Sensors with Resin Heads.

[Head thickness 0.4 mm *3]

Thick Metal Head That Resists Friction with the Workpiece

The 0.4-mm*3 metal head exhibits almost no wear due to friction with the workpiece or cleaning with metal brushes.
This helps prevent equipment down time due to sensor failure and reduces the frequency of replacement.

*2. Stainless-steel brush test with M12 model.
*3. For M12 model.

Stable Detection in Harsh Environments with Splatter Resistance and Durability

Spatter-resistant models with fluororesin-coated head are also available. Reduces adhesion of spatter to achieve stable detection. The tough all-stainless steel housing with a flame-retardant cable enables reliable application where spatter is present near welding machines.

Reduced Cleaning Frequency with Spatter Countermeasures

The spatter countermeasures reduce the risk of malfunction due to the buildup of metal debris or spatter.
Frequent cleaning with metal brushes is not required.
