Specifications for TNC Connectors

TNC Series connectors are miniature sized, and weatherproof and are electrically similar to BNC Series, except that they have a coupling method which utilizes a screw system giving them additional resistance against shock and vibration. They are especially designed for use from DC to 18 GHz, in vibration exposed equipment like in commercial and military radio telecommunications systems and avionics equipment. These connectors are particularly useful for applications in computer and medical equipment and test instrumentation. TNC Series have a constant impedance of 50 ohms and are available in a variety of cable configurations.

3 Piece Crimp

TNC three piece crimp connectors feature the same semi-captive contacts as the BNC which “click” into place assuring perfect installation. Each crimp pin has a vent hole for optional soldering. Soldering is recommended for all stranded conductors 26 AWG or smaller.

Part Number	RG/U Cable	Fig. No.
510A205F	58A/U, 58C/U, Stranded, 141/U	57
510A204G	59/U, 62/U, 210/U	57
510A204FV	58A/U, 58C/U, 141/U Plenum	58
RoHS compliant

Standard Clamp and Taper Grip

TNC standard clamp style is a simplified version of the original military style. It is required that the contact be soldered to the center conductor of the cable. The Taper Grip style connectors require little cable preparation. Strip off all but a length of center conductor, push the taper under the cable’s shield, solder the contact, and assemble.

510A304F	58A/U, 58C/U, Stranded, 141/U	50
510A304G	59/U, 62/U, 210/U	50
RoHS compliant

Twist-On

TNC Twist-On connectors are field installable and require no tooling other than a stripping tool for the cable preparation. The center conductor is inserted into Bomar’s unique Posi-Con™ contact, as the connector twists firmly onto the cable’s outer jacket.

Part Number	Gender	RG/U Cable	Fig. No.
510A405F	Male	58A/U, 58C/U, Stranded, 141/U	53
