E3ZR-C, Omron-Oil-resistant Photoelectric Sensors

 E3ZR-C, Omron-Oil-resistant Photoelectric Sensors

These 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.


Fiber Units for Reliable, Stable Operation in Cutting Oil Environments

  • Fluororesin cables that strongly resist cutting
  • Sealing methods that prevent gaps at joints block the ingress of cutting
  • IP67G * degree of protection (JIS C 0920 Annex 1)

*1. Values in parentheses indicate the minimum required distance between the Sensor and Reflector.

*2. 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.

*3. 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.
