Omron E2EW-QX20B1T30-M1TJ 0.3M Inductive Proximity Sensor

Technical Description

The Omron E2EW-QX20B1T30-M1TJ Inductive Proximity Sensor is designed for industrial automation systems that require dependable metal detection under demanding operating conditions. As a member of the Omron E2EW Series, this model combines a long sensing distance with a rugged stainless-steel housing and a full-metal sensing face, making it suitable for applications where sensors are exposed to welding spatter, cutting fluids, vibration, and mechanical impact.

The M30 threaded housing provides secure installation on heavy industrial equipment, while the integrated 0.3-meter M12 Smartclick pigtail simplifies wiring and enables faster replacement during maintenance. This connection method is particularly useful in automated production lines where minimizing downtime is an important operational objective.

The Omron E2EW-QX20B1T30-M1TJ Inductive Proximity Sensor offers a rated sensing distance of 20 mm and supports flush mounting, allowing installation in compact machine structures without compromising sensing stability.

Operating Principle

The sensor operates using inductive sensing technology. An internal oscillator generates a high-frequency electromagnetic field at the sensing face. When a conductive metallic object approaches the active area, eddy currents are induced within the target. These currents reduce the oscillator amplitude, which is continuously monitored by the internal detection circuit.

When the predefined threshold is reached, the sensor switches its PNP Normally Open output and sends a signal to the connected PLC, motion controller, or industrial automation system. Because no physical contact occurs during detection, the sensing process minimizes mechanical wear and provides stable repeatability throughout long production cycles.
