Cylindrical knobs/handles are often used on gear levers and handles instead of ball knobs DIN319.

These GN 519.2 cylindrical handles are made of blue plastic granulate that is FDA compliant as per FDA CFR.21 and EU 10/2011 as well as visually detectable or metal detectable.

The blue colour is used as it is easy to see with the human eye and is also easy to detect with optical monitoring systems. This allows monitoring of the production process, such as in food production, so that the process can be interrupted if foreign bodies are detected.

The plastic of the MDB handle also contains metal-detectable additives. Metal detectors will be triggered by this material from a particle volume of about 0.125 cm3, meaning that even hidden plastic chips can be detected.
