Chemical resistant Proximity Sensor
E2FQ Omron Chemical resistant Proximity Sensor use high-frequency oscillation. They resist heat, chemicals, and water better than Rectangular Sensors. They are available in both shielded and unshielded models.
E2FQ Omron Chemical resistant Proximity Sensor Components detect, measure, analyze, and process various changes that occur on productions sites, such as changes in position, length, height, displacement, and appearance. They also contribute to predicting and preventing future events.
- Housing and mounting are made of Fluororesin resistant to chemicals.
- Maximum sensing distance: 10
