DIXSG

DIXSG 2PCS BNC Female to TNC Male Coax Adapter

SKU CH-9YAS-RMH38

Two BNC female to TNC male 50 ohm coaxial adapters with pure copper centres and nickel-plated brass bodies rated for 500 mating cycles

  • Details,
  • Low-loss signal path with .2 dB insertion loss at 3 GHz
  • Pure copper center conductor ensures reliable conductivity
  • Nickel-plated brass body resists corrosion across -55 °C to 155 °C
  • Rated for 500 mating cycles for long service life
  • Two adapters included for multiple connection points

Connector type and impedance

This pack contains two BNC female to TNC male coaxial adapters rated at 50 ohms. They join a BNC male cable or device to a TNC female port in security cameras, CCTV systems, DVRs, SDI video, broadcast gear and wireless LAN equipment.

Signal loss and temperature range

Insertion loss is specified at .2 dB at 3 GHz with a VSWR of 1.2 GHz, keeping attenuation low across the operating band. The adapters function from -55 °C to 155 °C, suiting both indoor and outdoor installations.

Pure copper contacts and mating life

Center conductors are pure copper with nickel-plated brass bodies, delivering good conductivity and corrosion resistance. Rated for 500 mating cycles, they replace worn or mismatched ends on existing coax runs without needing new cable pulls.

Questions about this item

How do I install the BNC female-to-TNC male adapter without damaging the centre conductor?

Thread the TNC male pin onto the TNC female port by hand, then tighten a quarter-turn with a wrench; push the BNC male plug straight into the BNC female hole until the bayonet lugs click — forcing it sideways bends the pure copper centre conduct.

When will the nickel-plated brass body or the pure copper centre conduct need replacement?

The adapter is rated for 500 mating cycles; after roughly that many connect-disconnect operations the spring fingers or plating can wear enough to raise insertion loss above the specified .2 dB at 3 GHz.

What is the first performance limit reached during continuous high-power RF use?

Insertion loss reaches .2 dB at 3 GHz and VSWR stays at or below 1.2 up to 1.2 GHz; beyond that frequency the return loss degrades before the -55 °C to +155 °C temperature range becomes a factor.
