Omron E2ER/E2ERZ Proximity Sensors use high-frequency oscillation. They resist heat, chemicals, and water better than Rectangular Sensors. They are available in both shielded and unshielded models.
Proximity Sensors are available in models using high-frequency oscillation to detect ferrous and non-ferrous metal objects and in capacitive models to detect non-metal objects. Models are available with environment resistance, heat resistance, resistance to chemicals, and resistance to water.
Omron E2ER/E2ERZ Proximity Sensors Features and Benefits
- Fluororesin cable that withstands cutting
- A sealing method that eliminates gaps at cable joints and the resin filling work together to block ingress of cutting
- IP67G * degree of protection (JIS C 0920 Annex 1).

- Use the Sensor within the range in which the setting indicator (green LED) is ON (except D2 Models).
- The response frequency 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.
- The IP67G is the degree of protection which is defined according to the JIS (Japanese Industrial Standards).
- The IP67 indicates the same level of protection as defined by the IEC, and the G indicates that a device has resistance to oil.
- The Oil-resistant Component Evaluation Standards are OMRON’s own durability evaluation standards.
The Pre-wired Connector Model meets the degree of protection when it is correctly connected with an XS5@R Oil-resistant Connector. The degree of protection is not satisfied with the part where there is no XS5FR Oil-resistant Connector connected and cable wires are uncovered. And as for the Pre-wired Models, the degree of protection is not satisfied with the part where cable wires are uncovered
