Product Description
The LHi 968 series with standard Dual Element configuration is performance-proven in high-end
applications. The LHi 968 design provides for a reduced sensitivity to EMI and excellent White Light
Immunity (WLI). The PYD 1398 has higher RF immunity and is optionally available with grading
for lower white light sensitivity.
