E2EH-X D DC 2-Wire Models, Omron-Proximity Sensor

 

E2EH-X D DC 2-Wire Models, Omron-Proximity Sensor[/caption]

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.

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

*1. Use the yellow indicator on D1 Models as a guide.

*2. 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.

*3. The residual voltage of each E2EH-X@D@ DC 2-Wire Model is 5 V. When connecting to a device, make sure that the device can withstand the residual voltage. (Refer to page 9.)

*4. Operation with power supplied for 1,000 h has been verified at 110°C. Do not bend the cable repeatedly at 100°C or higher.

*5. IP69K Degree of Protection Specification

IP69K is a protection standard against high temperature and high-pressure water defined in the German standard DIN 40050, Part 9. The test piece is sprayed with water at 80°C at a water pressure of 80 to 100 BAR using a specified nozzle shape at a rate of 14 to 16 liters/min.

The distance between the test piece and nozzle is 10 to 15 cm, and water is sprayed horizontally for 30 seconds each at 0°, 30°, 60°, and 90° while rotating the test piece on a horizontal plane.
