Omron E2EW-QX20B1T30 2M Inductive Proximity Sensor

Technical Description

The Omron E2EW-QX20B1T30 Inductive Proximity Sensor is designed for dependable non-contact detection of metallic objects in industrial environments where mechanical durability and environmental resistance are essential. Its M30 threaded housing supports installation on production equipment requiring an extended sensing distance while maintaining a compact mechanical design.

This model belongs to Omron’s E2EW Series, which incorporates a full-metal sensing face and a fluororesin-coated stainless-steel housing to improve resistance against welding spatter, abrasive particles, oil, and coolant. The 20 mm sensing distance allows detection of metallic targets without physical contact, reducing component wear and improving repeatability.

The Omron E2EW-QX20B1T30 Inductive Proximity Sensor features a fixed 2-meter PVC cable for straightforward integration with industrial control panels, PLC systems, and machine control circuits.

Operating Principle

The sensor generates a high-frequency electromagnetic field through its sensing surface. When a conductive metal object enters the sensing zone, eddy currents develop inside the target. These currents absorb energy from the oscillator circuit, reducing its amplitude.

The internal electronic circuit continuously monitors these changes and switches the PNP output once the preset threshold is reached. Since no mechanical contact occurs during detection, the sensing process remains stable even in applications involving continuous machine cycles.

Applications

• Automated assembly equipment
• Material handling systems
• Industrial conveyors
• Transfer lines
