IFM E21324 is a fibre optic diffuse reflection sensor designed for object detection in industrial automation and robotic applications. It features a straight M3 sensing head and a 2000 mm fibre optic assembly. The sensor uses a bending-resistant design for flexible routing in compact machine installations. It is compatible with OBF, OO50 and OCF fibre optic amplifiers. The robust PMMA, stainless-steel and PE construction supports dependable operation in industrial environments.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
E21324 detects objects using the diffuse reflection principle. The sensor receives reflected optical energy from the target and works with a compatible fibre optic amplifier. This arrangement provides a compact detection solution without requiring a separate reflector at the target location. It is particularly useful for detecting objects within a defined machine sensing area. The design supports reliable detection for industrial automation applications.
The sensing head uses a straight configuration with an M3 sensing head thread. This compact arrangement allows installation in areas where space is limited. The straight sensing head provides convenient orientation toward the target. The stainless-steel sensing head contributes to mechanical durability. The compact construction makes the sensor practical for machine builders and automation integrators.
The 2000 mm fibre assembly allows the sensing point to be positioned away from the amplifier. The fibre has a minimum bending radius of approximately 5 mm, allowing flexible routing around machine components. PMMA is used as the fibre material, while PE provides the protective sheath. The stainless-steel fibre head provides additional mechanical strength. This combination is suitable for industrial environments and robotic applications.
The sensor can be used with OBF, OO50 and OCF fibre optic amplifier types. Its fibre range is approximately 10 mm with OBF, 30 mm with OO50 and 190 mm with OCF High Power. This allows users to select the amplifier according to the required sensing distance. The flexible amplifier compatibility makes the E21324 suitable for different automation layouts.
