E2EM-X@X@ DC 2-Wire Models, Omron-Long-distance Proximity Sensor

E2EM-X@X@ DC 2-Wire Models, Omron-Long-distance Proximity Sensor

 E2EM-X@X@ DC 2-Wire Models, Omron-Long-distance 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.


  • Long-distance detection at up to 30 mm enables secure mounting with reduced problems due to workpiece
  • No polarity for easy wiring with DC 2-wire
  • Cable protector provided as a standard
