The FIA-A-V is a high-speed fork light barrier sensor with integrated electronics and an analog output (0 to +5V), offering a switching frequency up to 100 kHz for fast, precise detection tasks. It uses a 905 nm infrared LED and can detect objects as small as 0.05 mm with high reproducibility, making it suitable for fine edge detection and high-speed process monitoring. Its aluminum housing is IP67-rated, oil-resistant, and built for industrial use, with available options for circular or rectangular apertures and various fork sizes. The sensor includes a blast-air connector to prevent contamination of the optics, supporting stable performance in dusty or oily environments. Typical applications include precision positioning, wire or thread break detection, and monitoring of fast-moving objects in packaging, textile, and automation systems.
