MetaClamp® LED Ring Light Series SGL

The new MetaClamp® LED Ring Light Series SGL is a powerful yet compact illumination system for sanitary processing equipment providing illumination and viewing through the same window.

This unique combination sight/light glass incorporates the L.J. Star MetaClamp® system with METAGLAS® safety windows. They can be used to view the interior of either new or existing sanitary processing equipment.

Unlike other solutions that used separate viewing and fiber optic light assemblies, this innovative and compact design mounts directly onto sanitary ferrules for use in combined sight and light ports (single port). The design is both less expensive and more durable for industrial settings, since it uses fewer sub-assembly components.

METAGLAS® safety windows with the MetaClamp® sanitary connection provide the strongest, most secure sanitary viewing option available. Essentially immune to catastrophic failure, these windows are comprised of stainless steel and borosilicate glass, fused together to create a window so uniformly compressed it tolerates both extreme pressure and temperature, serving reliably for years in applications where conventional soda lime or BoroPlus™ windows fail repeatedly.

Three sizes of the SGL Light attach directly to either a 2-1/2”, 3”, 4”, 6” or 8” MetaClamp® view port, which eliminates separate mounting of the light source. The polished housing is made of 316 stainless steel, which carries NEMA 4X and IP68 ratings.
