The N connector is an RF coaxial connector.

50ohm vs 75ohm

There are two incompatible versions of the N type connector that have a different size internal pin. The 75ohm version has a larger pin than the 50 ohm version and as a result can damage many female 50ohm connectors. using a 50ohm male connector with a 75ohm female wont do any damage although a good connection probably wont be made.
