E2E-X DC 3-Wire Models, Omron-Standard Proximity Sensor

 E2E-X DC 3-Wire Models, Omron-Standard Proximity Sensor

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 and Benefits

  • Standard Sensors for detecting ferrous
  • A wide array of variations. Ideal for a variety of
  • Models with different frequencies are also available to prevent mutual
  • Superior environment resistance with standard cable made of oil-resistant PVC and sensing surface made of a material that resists cutting
  • Useful to help prevent
  • Cable protector provided as a standard feature
