Omron, E2FM Series

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

The one-piece completely stainlesssteel 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

Main Performance Comparison to Previous OMRON Products

The chemical resistance has been certified by Ecolab Europe

*1. The response frequency of the DC switching section is an average value. Measurement conditions are as follows:
standard sensing object, a distance of twice the standard sensing object, and a set distance of half the sensing
distance.
*2. NC (normally closed) models are also available. Contact your OMRON representative.
