The Omron E2EW-QX12B3T18-M1TJ 0.3M Inductive Proximity Sensor is designed for industrial automation systems that require dependable metal detection together with flexible connector installation. Unlike fixed-cable versions, this model incorporates a short 0.3 m pigtail cable terminated with an M12 connector, providing convenient routing inside machine panels while simplifying sensor replacement.
As a member of the E2EW Series, the sensor combines a fluororesin-coated sensing surface with a stainless-steel housing to improve durability in environments exposed to welding spatter, oil, coolant, and mechanical stress. IO-Link COM3 communication supports parameter configuration, diagnostics, and device identification within modern automation architectures.
Technical Description
The Omron E2EW-QX12B3T18-M1TJ 0.3M Inductive Proximity Sensor features an M18 cylindrical body with quasi-flush installation and a nominal sensing distance of 12 mm. It operates on a 10–30 VDC supply and provides both Normally Open and Normally Closed PNP switching outputs.
The integrated 0.3 m pigtail cable allows installers to position the connector away from confined mounting locations while maintaining compatibility with standard M12 extension cables. This configuration is often selected for machinery where direct connector access would otherwise be restricted.
Operating Principle
The sensor detects conductive metal objects through electromagnetic induction. An oscillator inside the sensing head creates a high-frequency electromagnetic field. When a metallic object enters this field, eddy currents are induced within the target, causing measurable changes to the oscillator circuit.
The internal electronics continuously monitor these changes and activate the switching output when the defined sensing threshold is reached. Since detection occurs without physical contact, there is no mechanical wear during normal operation.
IO-Link communication enables parameter storage, sensor identification, status monitoring, and diagnostic information exchange with compatible IO-Link masters.
