Omron 2 Wire 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.
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 E2EH-X D DC 2 Wire Features
- Improved resistance to detergents and rusting
- Applicable to 120?C (with DC 3-wire connection) (Heat resistance verified to 1,000 hours.)
- Resists typical detergents and disinfectants used in the food industry
- Water-resistant under high-temperature, high-pressure cleaning based on DIN 40050-9. (Pressure: 8,000 to 10,000 kPa, Water temperature: 80?C, For 30 s at all angles
