​1. Product Overview: IFM E11252 High-Temperature Inductive Proximity Sensor

​
The IFM E11252 is a rugged inductive proximity sensor engineered for extreme industrial environments requiring reliable non-contact detection of metallic objects. Featuring a stainless steel (AISI 304) housing with IP69K protection, it operates flawlessly in high-temperature settings (-40°C to +150°C), harsh washdowns, and chemically aggressive conditions. With a sensing range of up to 30 mm for ferrous metals, this sensor delivers precise feedback for automated systems in foundries, steel mills, and food processing plants. Its PNP normally open (NO) output and 10–30V DC power supply ensure seamless integration with PLCs and industrial controllers. The E11252’s compact M30x1.5 design and resistance to mechanical stress make it ideal for heavy machinery and high-vibration applications.

​2. Key Technical Specifications​

• ​Detection Range: 30 mm (for mild steel).
• ​Output Type: PNP, NO (3-wire, 2 m PUR cable).
• ​Supply Voltage: 10–30V DC (±10%).
• ​Current Consumption: ≤25 mA.
• ​Switching Frequency: 500 Hz.
• ​Housing Material: AISI 304 stainless steel.
• ​Protection Class: IP69K (high-pressure/steam resistance).
• ​Operating Temperature: -40°C to +150°C.
• ​Certifications: CE, cULus, IECEx, ATEX (Zone 22).

​3. Industrial Applications and Use Cases

​
The E11252 excels in foundries for detecting molten metal molds and monitoring conveyor belt positions in high-heat zones. In food processing, its IP69K rating ensures hygiene compliance in CIP (Clean-in-Place) systems for tank level monitoring and packaging line automation. Automotive manufacturing uses it to verify engine block positioning during robotic assembly, while steel mills deploy it for coil alignment in rolling mills. Its ATEX certification allows safe operation in explosive dust environments like grain silos and chemical storage facilities. Additional applications include paper mill machinery, plastic injection molding, and offshore drilling equipment exposed to saltwater corrosion.

​4. Competitive Advantages and Unique Features​

• ​Extreme Temperature Tolerance: Reliable performance in -40°C to +150°C, surpassing standard sensors.
• ​Unmatched Durability: Stainless steel housing resorts to corrosion, abrasion, and high-pressure washdowns.
• ​Long Sensing Range: 30 mm detection for large or distant metallic targets.
• ​Safety Compliance: ATEX/IECEx Zone 22 certification for hazardous dust environments.
• ​Low Maintenance: Contactless design eliminates wear, reducing lifecycle costs.

​5. Functional Capabilities and Operational Benefits

​
The E11252 provides fail-safe detection with a rapid response time (≤1.5 ms), critical for high-speed production lines. Its short-circuit and reverse polarity protection enhance system reliability, minimizing unplanned downtime. The PUR cable resists oils, acids, and UV degradation, ensuring longevity in outdoor or chemically aggressive settings. By enabling precise object detection in extreme conditions, it optimizes process efficiency and safety in industries like metalworking, energy, and pharmaceuticals. The sensor’s compatibility with Industry 4.0 networks supports predictive maintenance, transmitting diagnostic data to central systems for real-time health monitoring.
