Built for use in desktop or mobile applications, the SLK-80 features a conductive plastic case, adjustable green backlighting that is also available in a night vision (NVIS) compatible configuration, and is sealed to IP68 specifications. The conductive plastic case for the SLK-80 was designed for additional electro magnetic interference (EMI) performance. It has multiple ground access points internal to the PCB electronics, and is designed and intended for use in very harsh EMI environments requiring 461 standards.
