The IFM E21103 is a fibre optic through-beam sensor designed for object detection in industrial automation applications. It features an M3 sensing-head thread and a 2000 mm total fibre length. Its high-flex design allows the fibre to be routed through compact machine spaces with a minimum bending radius of 3 mm. The PMMA fibre construction provides flexible and reliable optical transmission. The fibre can be cut to the required length for convenient installation.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The E21103 works as a through-beam fibre optic sensor with compatible IFM fibre amplifiers. It is suitable for detecting objects across a defined sensing path. Compatible amplifier options include OB50, OBF, OCF and OO50. The available range depends on the selected amplifier. This provides flexibility for different machine and automation requirements.
The fibre is designed for applications where a very small bending radius is required. Its minimum bending radius is approximately 3 mm. The PMMA fibre and PE sheath provide a flexible construction for routing through restricted spaces. The straight aluminium sensing head provides a compact sensing interface. This makes the fibre useful in machinery with limited mounting space.
The E21103 uses an M3 sensing-head thread and a 14.5 mm sensing-head length. Its compact head design is suitable for small sensor mounting locations. The 2000 mm total length provides sufficient flexibility for many industrial installations. The fibre can be cut to size using the appropriate cutter. The product is supplied with mounting accessories for convenient installation.
