The IFM E21248 is a specialised protective housing with an active cooling system designed to shield IFM’s O1D series sensors when operating in extreme industrial environments. By combining robust construction, active cooling capability, and resistance to high temperatures and pressures, this housing ensures long-term reliability and durability of sensitive sensors in the field.

One of the standout features of the E21248 is its ability to handle ambient temperatures ranging from -10 to 180 °C. This wide thermal operating range makes it particularly well-suited for applications in industries such as steel production, glass manufacturing, food processing, and heavy machinery, where elevated or fluctuating temperatures are a constant challenge. The integrated active cooling system ensures that the sensor housed within maintains stable functionality even under extreme heat loads.

Built with exceptional durability, the E21248 is constructed from high-quality anodised aluminium (transparent anodised for the housing, black anodised for the cover and framework), combined with a float glass front lens. This robust material composition provides superior resistance to mechanical stress, thermal load, and corrosion, ensuring the housing’s long service life even in aggressive industrial environments. Additional elements, such as the brass nickel-plated cable gland and nozzle, and FKM sealing, enhance resistance to chemicals, wear, and environmental stressors.

The E21248 is designed not only for durability but also for safety and reliability. With a pressure rating of up to 10 bar, it can be deployed in pressurised environments where additional robustness is required. The float glass front lens ensures clear optical performance, maintaining the accuracy of the O1D sensor while protecting it from dust, debris, or physical impacts.

Compact yet solid, with dimensions of 112 x 70 x 108 mm and a weight of 1270.5 g, the housing offers a strong and stable platform for sensor mounting without occupying excessive space. Its precision engineering ensures that the cooling system, sealing, and optical components work in harmony to protect and extend the operational lifespan of the O1D sensor.

Applications of the E21248 include any industrial setting where O1D sensors are exposed to heat, mechanical stress, or aggressive environments. For example, in high-temperature manufacturing processes, the housing ensures uninterrupted sensor performance, contributing to greater operational uptime and reduced maintenance requirements. Its rugged design also makes it suitable for use in harsh outdoor or heavy-duty conditions where both cooling and protection are vital.

In summary, the IFM E21248 is an essential accessory for protecting O1D sensors in extreme industrial environments. With its active cooling system, ability to withstand temperatures up to 180 °C, pressure resistance to 10 bar, and durable anodised aluminium and glass construction, it ensures reliable sensor performance, long-term durability, and peace of mind for operators working in the most demanding conditions.
