The IFM E21169 is a laser-protection window designed for compatible DUALIS vision sensors used in industrial inspection systems. It provides protection for the sensor front pane while incorporating a dedicated laser-protection filter. The compact 57 × 42 × 4.9 mm design uses a black die-cast zinc housing with a PMMA optical window. The filter is made from polycarbonate and is specified for the 880–1064 nm range. It provides a practical protective accessory for applications involving compatible laser wavelengths.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The E21169 is designed to provide additional protection against specified laser wavelengths while maintaining a suitable optical path for the vision sensor. Its filter is specified for the 880–1064 nm range and L5 protection according to EN 207. This makes the accessory suitable for compatible laser-based industrial vision applications. Proper system compatibility should be verified before installation. The protective window provides an additional layer of safety and sensor protection.
In addition to laser protection, the E21169 helps protect the sensor front pane against soiling, impact and mechanical damage. The protective window acts as a physical barrier between the sensor and the surrounding machine environment. This can help maintain the condition of the sensor optics during continuous operation. The robust housing supports industrial installation. The compact design keeps the accessory close to the sensor front.
The E21169 measures 57 × 42 × 4.9 mm and weighs approximately 42 g. The housing is manufactured from black die-cast zinc and the main lens is PMMA. The laser filter uses polycarbonate material. This combination provides a compact protective assembly suitable for compatible DUALIS vision sensors. The product is supplied as one protective pane.
