The IFM E21102 is a fibre optic through-beam sensor designed for reliable object detection in industrial automation systems. It uses a flexible acrylic fibre construction with an M4 sensing-head thread and a total length of 2000 mm. The high-flex design allows installation where small bending radii are required. It supports long-range detection when paired with compatible fibre-optic amplifiers. The fibre can also be cut to the required length for practical installation.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The E21102 operates using the through-beam sensing principle. It is designed for use with compatible IFM fibre-optic amplifiers such as OB50, OBF, OCF and OO50. Depending on the amplifier, the fibre provides different detection ranges. This makes the product suitable for a variety of object-detection applications. The arrangement is useful where conventional sensor installation is difficult.
The fibre optic assembly is designed for applications requiring a small bending radius. It has a minimum bending radius of only 3 mm. The fibre uses PMMA material with a PE sheath and aluminium fibre head. This construction supports flexible routing around machine components. The high-flex design makes it suitable for compact automation installations.
The E21102 has a total fibre length of 2000 mm. The fibre can be cut to the required length using a suitable fibre cutter. This provides flexibility during machine installation and system integration. The M4 sensing-head thread allows suitable mounting arrangements. The long fibre length is useful where the amplifier and sensing point are separated.
