Standard BNC RF connectors have a bayonet coupling and these can be problematic in applications where they need to be connected frequently or where access is difficult. The push-pull design of the Damar & Hagen BNC-PP and BNC/DS-PP RF connectors overcome these issues and they are also more suitable for use with the latest HDTV technology. BNC-PP connectors are available in 50 and 75 ohms versions and are intended for analogue signal transmission and the BNC/DS-PP 75 ohms connector is intended for digital serial signal transmission. This patented design is completely compatible with a standard BNC interface and also requires no special installation tooling.
Other advantages of these versatile new connectors are that gold-plating both the inner and outer conductor reduces ‘skin effect’ thus improving high frequency properties and the contact resistance is decreased permanently due to the improved corrosion properties. In addition, the contact pressure of the connector’s outer conductor is increased by using contact tongues under-laid with an additional spring washer and this improves operational characteristics making them suitable in high vibration and shock conditions as experienced in outside broadcast vehicles and similar applications.
BNC-PP and BNC/DS-PP RF connectors are available in many versions and cable connectors in both crimp and solder versions can terminate cable sizes from 2mm to 11mm in diameter.
