LMS- Moisture-sealed IP 56/ NEMA 4c
VCC’s LMS Series Litepipe® provides display panel moisture seal and 180° viewing angle.
This lens and Litepipe® unit was developed to provide moisture sealing and dust control for display panels when the LED is attached to a circuit board. The LMS Series is designed for use with surface mount LEDs as well as standard thru-hole LEDs, horizontally or vertically circuit board mounted.
The Litepipe® is tubular in shape attached to a lens. The lens is fitted with a gasket that provides sealing for both moisture and dust. Panel assembly is easily accomplished. Slip the unit through a .281” panel opening and slide the retaining ring (RNG 268) over the Litepipe® barrel. While holding the lens surface tightly against the panel, press the ring on using a 5/16” deep socket. The gasket is compressed as the ring is forced into place against the rear of the panel. This leaves the circuit board free from attachment to the display panel allowing for easy board insertion or removal.
The Litepipes® are molded from an optical grade acrylic plastic for clarity and optimum light transmission. The Litepipe® tooling is highly polished providing a smooth, scratch-free surface to the finished Litepipe®. This produces an optimum surface for maximum light refraction and ultimate transmission. The lenses are molded from polycarbonate that is rated UL 94-V0.
Tests by an independent testing laboratory have shown that the LMS lens unit meets IP 56/ NEMA 4 requirements providing an effective seal against water and dust. In addition to the water tests, the unit and its retaining system have been tested up to 6Gs of shock and from 0 to 2000 Hz of vibration. Tests also included storage and operating temperature ((-40°C to +85°C), solar, ice and UV). The conclusion attained upon completion of these tests was that the LMS Series exceeded all test criteria.
