Coaxial Connector Telegärtner J01008A0012

The Telegärtner J01008A0012 coaxial connector combines a BNC female interface with a TNC male interface in a single adapter designed for high-quality signal transmission. It is intended to provide a reliable link between devices with different coaxial connector types, maintaining impedance continuity and low insertion loss. The connector is suitable for professional telecommunications, broadcasting, and measurement setups where stable RF performance and mechanical robustness are required.

Advantages

This adapter offers precise mechanical fit and secure coupling between BNC and TNC connectors, reducing the risk of intermittent connections. Its construction is engineered to preserve signal integrity across the connection, providing low reflection and minimal attenuation at typical RF frequencies. The compact form factor and durable materials ensure longevity in rack-mounted and field environments.

Suitable for

• Connecting BNC-equipped test equipment to TNC-equipped devices
• Integrating mixed-connector systems in broadcast and production racks
• Temporary or permanent cabling solutions in RF measurement setups
• Telecommunications interconnects where connector type conversion is needed

Key specifications

• Connector types: BNC (female) to TNC (male)
• Impedance: Designed for 50 ohm coaxial systems
• Construction: Precision metal housing for mechanical stability
• Environmental durability: Suitable for typical professional indoor and sheltered field use
• Compatibility: Works with standard BNC and TNC cables and devices designed for 50 Ω operation

How to use

Align the BNC female side with the corresponding BNC male connector and engage the bayonet coupling until it locks. On the TNC side, align the keyed male connector and rotate until a secure threaded engagement is achieved. Verify the mechanical connection is firm and, if applicable, perform a continuity or insertion-loss check with suitable test equipment to confirm signal integrity before placing the connection into service.

Usage recommendations

Use the adapter with 50 Ω systems and avoid exposing it to prolonged moisture or corrosive environments. For best RF performance, minimize the number of adapters and transitions in a signal path and periodically inspect connector interfaces for contamination or wear.
