The FT 55-RLHM reliably detects black to shiny surfaces. A black object measuring just 2 mm in size can be reliably recognised even at a distance of 1 m. Sensor setup is quick and simple thanks to user-friendly operating elements and an LCD display in which the distance value is continuously visible. This makes FT 55-RLHM the most efficient sensor of its category. Pre-configured application modes make settings particularly reliable and simple.
