VCC has strengthened its LED lens product offering with the development of NEMA 4-rated, low-profile button type lens assemblies. The CMS 442 and HMS 462 have been designed not only to meet the needs of all indoor indication lighting applications, but also harsh environments.
Combining simple and fast assembly with reliability and ruggedness, they have been proven in heavy-duty panel applications that require NEMA 4 and moisture-proof protection.
The lens assemblies feature uniquely designed spiral mating threads that provide an enhanced mounting system. Tested by an independent laboratory, this ruggedised design exceeds all test criteria for NEMA 4 and beyond, including water seal depths down to 100 m, shock up to 6 G, vibration up to 6 G from 0 to 2000 Hz, temperature cycling from
-40°C to +105°C, UV resistance, dust sealing and ice encasement.
Featuring a smooth, clean look with a convex surface protruding just above the panel, their spiral mating threads enable quick assembly to the front panel. With less than a full turn, the lens is tightly mounted to the panel using the included lock washer and retaining ring. The circuit board is completely independent of the display panel, simplifying installation or removal for assembly or repair.
In addition, the lens assemblies increase the aesthetics of display panels. The low-profile design optimises the light output of the LED
by reducing the ambient light effect upon the lens. The lens can increase the viewing angle to 180 degrees by the use of patented VCC diffusion ring technology.
The CMS 442 is used for 5 mm LED applications with a 7,92 mm diameter mounting hole, while the HMS 462 provides a 10 mm LED solution with a 16,56 mm diameter mounting hole. For board-to-panel applications, these lenses can also be paired with VCC light pipes and cable assemblies.
