English Introduction
The Omron E2E-X18MEI is an inductive proximity sensor designed for metal object detection in industrial automation applications. With an operating voltage range of 12-24VDC, this cylindrical sensor provides reliable non-contact detection for position sensing and limit control in machinery, metallurgy, and chemical processing equipment. Its robust construction ensures long-term operation without mechanical wear. 515
Key Features
Utilizing high-frequency oscillation principle, the E2E-X18MEI demonstrates high sensitivity to ferrous metals. The stainless steel housing and PBT sensing face offer excellent resistance to cutting fluids and industrial contaminants. It features built-in surge protection and short-circuit prevention, with NPN output configuration supporting 0.4kHz response frequency. The 18mm sensing distance (±10%) remains stable across -25°C to +70°C operating temperatures. 1229
Mechanical Design
This sensor provides M30 threaded mounting options with either cable or connector versions (standard 2m cable). The compact cylindrical form (42mm diameter × 60mm length, 130g weight) facilitates installation in confined spaces. Optimized electromagnetic design minimizes mutual interference while maintaining vibration resistance (10-55Hz) and shock endurance (500m/s²). 310
Typical Applications
Ideal for position detection, object counting, and equipment protection in automated systems. Common uses include tool positioning in CNC machines, product counting in packaging lines, and safety limit switching in metallurgical equipment. The IP67-rated sealed construction ensures reliable performance in environments with cutting fluids or coolants. 627
Performance Benefits
The sensor delivers precise detection with fast response, maintaining consistent repeat accuracy. Contactless operation eliminates arcing and mechanical wear issues. With residual voltage below 3V (at 100mA load), it demonstrates excellent compatibility with most PLC inputs. Standardized dimensions allow easy replacement or upgrade within the E2E series. 1423
