Product Description
TNC-PM-1.1 — TNC Male Replacement Pin - 50-Pack
1.1mm Bore for RG-58A / LMR-195 Coaxial Cable. Replace damaged TNC male center pins without replacing the entire connector. The TNC-PM-1.1 is a spare/replacement center pin contact designed for TNC male crimp-style connector assemblies using coaxial cable with a larger center conductor, including RG-58A and LMR195.
Each center pin features a 1.1mm bore hole sized to accommodate the larger center conductors found in these cable types. The machined metal contact provides a reliable electrical connection when properly crimped or soldered into a compatible TNC male connector body.
A convenient bulk pack for RF technicians, cable assemblers, ham-radio operators, installers, repair shops, and anyone who regularly terminates RG-58A or LMR195 coaxial cable.
Key Features
- 50 Count Bag
- 1.1mm bore hole for larger center conductors
- Designed for RG-58A and LMR195 coaxial cable
- Replacement for damaged, lost, corroded, or improperly terminated TNC center pins
- Ideal for 3-piece TNC male crimp connector assemblies
- Gold-plated conductive surface helps provide excellent electrical conductivity and oxidation resistance
- Precision-machined construction
- Useful for connector repair, custom cable assembly, RF equipment, test leads, and field service
- Allows replacement of the center contact without discarding an otherwise usable TNC connector
Cable Compatibility
| Coaxial Cable | Conductor Bore Size |
|---|---|
| RG-58A | 1.1mm |
| LMR195 | 1.1mm |
Important: Center-pin bore dimensions must match the coaxial cable's center conductor. The TNC-PM-1.1 is specifically intended for cables with approximately 1.1mm center conductors and is not a universal replacement for all TNC connectors.
Repair & Replacement
The TNC-PM-1.1 is an economical solution when the center contact of a TNC male connector becomes damaged, bent, corroded, lost, or improperly terminated. Replacing only the center pin can save an otherwise serviceable connector and cable assembly.
It is also well suited for technicians and installers building custom RF, radio, communications, test-equipment, CCTV, and instrumentation cables where individual connector components are needed.
Electrical Performance
The center contact is intended for use in compatible TNC connector assemblies where maintaining a proper center-conductor connection is critical to signal integrity. The finished connector's impedance and frequency performance depend on the complete TNC connector design, cable, and termination—not the replacement pin alone.
