The IFM E21133 is a protective cover designed for O1D optical distance sensors. It provides additional protection to the sensor front pane against contamination, impact and mechanical damage. The compact 42 × 4.6 × 42 mm design enables convenient installation without adding significant bulk. The cover uses a black die-cast zinc bezel, transparent PMMA front pane and FPM sealing.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The protective cover helps protect the front optical area of compatible O1D sensors from environmental contamination and accidental mechanical contact. This can help maintain reliable sensing performance in industrial environments where dust, dirt or impacts may occur.
The bezel is manufactured from black-finished die-cast zinc, while the front pane uses transparent PMMA. An FPM seal provides additional protection around the cover assembly. Stainless-steel screws are supplied for installation.
The compact 42 × 4.6 × 42 mm dimensions make the E21133 suitable for installations where space is limited. Its dedicated design provides a practical protection solution for compatible O1D sensors.
