The IFM E21107 is a compact fibre optic diffuse reflection sensor designed for short-range object detection in industrial automation systems. It is suitable for installation in areas where access is restricted and a flexible fibre-based sensing arrangement is required. The sensor uses a straight M3 sensing head and a 2000 mm fibre length for convenient installation. Its high-flex design supports a minimum bending radius of only 3 mm. The product is compatible with suitable IFM fibre-optic amplifiers and can be cut to the required installation length.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The E21107 is designed to operate as a diffuse reflection sensor. It detects objects using reflected light received through the fibre arrangement. With suitable amplifiers, it provides short detection ranges appropriate for compact machine applications. The OCF high-power amplifier provides a higher range than standard amplifier options. This makes the sensor suitable for precise detection close to the sensing head.
The fibre assembly has a minimum bending radius of 3 mm, making it suitable for tight machine layouts. The high-flex design allows the fibre to be routed around components without requiring large installation spaces. PMMA is used for the fibre, while the fibre head is made from aluminium and the sheath from PE. The 2000 mm total length allows flexible positioning between the amplifier and sensing point. This makes installation easier in complex machinery.
The E21107 uses an M3 sensing-head thread for compact mounting applications. Its straight sensing head provides a simple mechanical arrangement for sensor installation. The 20 mm sensing-head length allows convenient positioning at the detection point. The small fibre diameter supports installation in areas where space is restricted. This makes the product suitable for compact automation and inspection equipment.
