Superior PIM Performance and Compact Footprint
TC-400-4310M-X combines the proven reliability of the LMR-400 coaxial cable series with the advanced, low-PIM performance of the 4.3/10 mini DIN Male interface. This connector is the ideal choice for modern wireless infrastructure where Passive Intermodulation (PIM) stability is critical.
- Compact 4.3/10 Interface: Offers the same robust mechanical and electrical performance as the larger 7/16 DIN but in a smaller, lighter footprint, allowing for increased port density on modern remote radio heads (RRH) and base stations.
- Solder Center Pin (TC Style): Features a solder-pin inner contact for a permanent, high-integrity electrical bond, making it an excellent choice for stranded center conductors and highly critical installations in LMR-400 coaxial cable.
- Extremely Low PIM: The 4.3/10 design inherently minimizes PIM, which is essential for maintaining signal quality in LTE and 5G networks.
- Superior Environmental Resistance: Constructed with a Silver-plated inner contact and White Bronze (Alballoy) body finish for maximum corrosion resistance and excellent conductivity.
- High Frequency Support: Stable 50 Ohm impedance engineered for reliable performance up to 6 GHz, supporting current and future wireless bands.

The 4.3/10 Advantage in Telecom
The 4.3/10 connector standard is rapidly replacing older 7/16 DIN and N-Type interfaces in modern wireless deployments due to its superior features:
| Feature | 4.3/10 Advantage | Benefit to Your Network |
| Size & Weight | Significantly smaller and lighter than 7/16 DIN. | Increases Port Density on sensitive remote radio heads and small cells. |
| PIM Stability | Design minimizes PIM generation through decoupled electrical and mechanical plane. | Improved Network Quality and higher data throughput, critical for 5G. |
| Installation Torque | Torque requirement is lower and less critical to performance. | Easier, more repeatable installation in the field. |
Installation Method: Maximum Reliability
The TC-400-4310M-X uses the robust TC-style termination method for uncompromised signal transfer:
- Preparation: Use the compatible CST-400 stripping tool to expose the center conductor and braid.
- Solder Pin: The center pin is soldered directly onto the center conductor, ensuring a permanent, low-loss electrical connection.
- Crimp Shield: The outer ferrule is crimped securely over the cable jacket and braid for environmental sealing and superior pull strength.
