The IFM E21166 is a plastic protective pane designed for compatible DUALIS vision sensors used in demanding industrial and food-related applications. It protects the sensor front pane from contamination, impact and mechanical damage. The compact 57 × 42 × 4.9 mm design provides convenient integration with compatible sensor systems. It uses a black die-cast zinc housing and PMMA lens. The design is intended to support process reliability where sensor protection is important.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The E21166 is specifically designed as a protective window for applications associated with food-industry environments. Its purpose is to protect the front optical surface of the vision sensor against contamination and physical damage. This helps maintain consistent sensor operation during production processes. The protective construction provides an additional barrier between the sensor optics and the surrounding environment. It is suitable for compatible DUALIS vision systems.
The protective pane helps reduce the exposure of the sensor front surface to dirt, impact and shock. This is particularly useful in industrial production environments where equipment may be exposed to mechanical contact or contamination. The robust design supports dependable sensor operation. The accessory is designed for easy and economical installation. It can be replaced when required without replacing the complete vision sensor.
The E21166 uses a PMMA lens combined with a black die-cast zinc housing. Its compact 57 × 42 × 4.9 mm dimensions allow convenient integration with compatible vision sensors. The product weighs approximately 42.7 g. The compact construction adds protection without significantly increasing the overall sensor assembly size. It is supplied as one piece.
