Omron E2EW-QX12C318-M1 Inductive Proximity Sensor

The Omron E2EW-QX12C318-M1 Inductive Proximity Sensor is designed for reliable, non-contact detection of metallic objects in industrial automation systems. As part of the E2EW Series, this model combines an M18 threaded stainless-steel housing with a fluororesin-coated exterior and a metal sensing face, making it suitable for applications where mechanical durability and environmental resistance are important. The sensor features a 12 mm sensing distance, a three-wire DC PNP normally open output, and an M12 connector for efficient installation and maintenance.

Technical Description

The Omron E2EW-QX12C318-M1 Inductive Proximity Sensor is intended for detecting metallic targets without physical contact. The quasi-flush mounting design provides flexibility during machine integration while maintaining stable sensing performance. The stainless-steel housing helps protect the sensing element from mechanical impacts, and the fluororesin coating contributes to improved resistance against contaminants commonly encountered in industrial production environments.

The integrated M12 connector simplifies replacement and maintenance by allowing the sensor to be disconnected without removing fixed wiring from the control cabinet.

Operating Principle

The sensor generates an electromagnetic field at the sensing face. When a conductive metal object enters the sensing range, eddy currents are produced within the target. These currents modify the internal oscillator characteristics.

Once the detection threshold is reached, the internal electronics switch the PNP normally open output. Because detection occurs without physical contact, there is minimal mechanical wear, allowing consistent operation throughout continuous production cycles.

Typical Applications

• Automated assembly equipment
