Omron E2EW-QX12C118-M1 Inductive Proximity Sensor

The Omron E2EW-QX12C118-M1 Inductive Proximity Sensor is designed for industrial automation systems requiring dependable non-contact metal detection together with digital communication capabilities. This model combines an NPN Normally Open switching output with IO-Link COM3 communication, making it suitable for both conventional control systems and modern data-driven manufacturing environments.

Its M12 connector simplifies installation and replacement, while the fluororesin-coated sensing surface improves resistance to welding spatter. The stainless-steel housing provides mechanical durability for demanding production environments exposed to coolant, oil, dust, and vibration.

Technical Description

The Omron E2EW-QX12C118-M1 Inductive Proximity Sensor features an M18 cylindrical housing with quasi-flush mounting and a nominal sensing distance of 12 mm. It operates from a 10–30 VDC power supply and offers an NPN Normally Open switching output alongside IO-Link COM3 communication for diagnostics and parameter management.

The connector-based design allows rapid sensor replacement during maintenance without disconnecting permanent field wiring. This helps reduce service time and simplifies machine maintenance procedures.

Operating Principle

The sensor operates using electromagnetic induction. A high-frequency oscillator generates an electromagnetic field around the sensing face. When a metallic object enters this field, eddy currents are induced within the target material. These currents influence the oscillator circuit, allowing the internal electronics to detect the object’s presence and activate the output.

Since detection is performed without mechanical contact, the sensing process minimizes wear while providing repeatable switching performance during continuous production cycles.

When connected to an IO-Link master, the sensor can exchange device identification, operating status, parameter settings, and diagnostic information with the automation controller.
