About the LC Interface

The LC series connectors are commonly used in high power applications for applications in the mil/aero and industrial equipment markets. The design of the interface allows for the outer diameters to engage prior to the inner diameters giving the user a measure of protection for the high voltage environment. Incorporating a polyethylene dielectric, the LC connector is designed for optimal use with cables that utilize the same polyethylene dielectric such as RG217. Voltage rating is up to 5000 volts.
