Mini-BNC Connectors

Amphenol RF Mini-BNC Connectors are designed for telecommunication and broadband applications for higher connector densities while preserving the positive characteristics of the Amphenol full-size BNC connectors for 75Ω systems. This allows 40% more interconnects in the same area. The Mini BNC series provides a positive locking bayonet system that offers a key advantage over a threaded alternative with quick connect/disconnect and a positive mechanism that can be felt when mated. These connectors are an ideal drop-in replacement for most high-density applications using SMB or SMZ jacks.
