Reed Switch Glass

"Reed Switch Glass" – a name derived from its application: The glass encapsulation of reed switches using special cut to size precision glass tubing.

SCHOTT’s 8516 reed glass tubing was specially developed for the encapsulation of reed switches. Typical tubing diameters range from just more than 1 to more than 5 mm. According to individual customer requirements, tubing is precisely cut to size. Sections can be as short as 5 mm for truly miniaturized applications. To ensure excellent rim quality, all sections are slightly fire-polished at both ends.

8516 is green due to its high iron content, which ensures particularly high IR absorption rates. This enables our customers to seal this glass in their process absolutely contamination free by using light (e.g. using Nd-Yag lasers or tungsten halogen lamps) rather than flames.
