- Different designs and sensing heads for a large variety of applications - For installation in places where access is difficult - For installation in places where access is difficult - For the reliable detection of tiny objects - Resistant to various aggressive chemicals Fibre optic systems are used where mounting space for photoelectric standard sensors is restricted. The evaluation unit and the fibre optics are mounted separately. These systems can therefore be installed in places where access is difficult. In addition to more than 100 types of acrylic and glass fibre optics with different sensing heads, ifm offers a large variety of components for the installation and operation of fibre optic systems. The range covers mounting clamps, special fixtures, coupling systems, cutters, diaphragms and lens attachments.
