Omron E2EW-QX12C118 2M Inductive Proximity Sensor

The Omron E2EW-QX12C118 2M Inductive Proximity Sensor is designed for stable non-contact detection of metallic objects in industrial automation systems. Equipped with a fixed 2 m cable, this model combines reliable inductive sensing with IO-Link COM3 communication, allowing both conventional switching and digital diagnostics in modern manufacturing environments.

Its fluororesin-coated sensing face helps reduce welding spatter adhesion, while the SUS303 stainless-steel housing enhances mechanical durability in applications exposed to coolant, oil, dust, and vibration. The cable connection makes the sensor suitable for installations where permanent wiring is preferred.

Technical Description

The Omron E2EW-QX12C118 2M Inductive Proximity Sensor features an M18 cylindrical housing with a quasi-flush mounting design and a nominal sensing distance of 12 mm. It operates on a 10–30 VDC supply and provides an NPN Normally Open switching output together with IO-Link COM3 communication.

The robust construction allows reliable operation in demanding industrial environments. The fixed 2 m cable offers straightforward installation for machinery where connector interfaces are not required.

Operating Principle

The sensor generates a high-frequency electromagnetic field at its sensing surface. When a conductive metal object enters the sensing range, eddy currents are induced in the target. These currents alter the oscillator characteristics inside the sensor, allowing the internal electronics to recognize the presence of the object and activate the output.

Because the sensing method is completely contactless, mechanical wear is eliminated during normal operation. Through IO-Link communication, operating parameters, diagnostic information, and device identification data can be exchanged with compatible controllers.
