Description
 This connector is engineered for heavy-duty infrastructure where internal chassis components must interface with external 1/4″ feeder lines. The clamp design is preferred over crimping for its superior mechanical strength and electrical stability, especially in high-vibration environments. It utilizes PTFE (Teflon) insulation for high voltage handling and integrated silicone O-rings to achieve an IP68 waterproof rating, shielding internal equipment from moisture ingress.
The 4-hole flange ensures that the connector can withstand the significant installation torque required for 7/16 DIN plugs (up to 25-30 Nm) without shifting. The silver-plated phosphor bronze inner contact and non-magnetic materials are critical for achieving PIM levels of ≤ -155 dBc, preventing signal interference in sensitive 5G and LTE networks.
Key Technical Advantages
-
Chassis Stability: The 4-hole square flange allows for secure bolting to metal enclosures, providing a low-resistance electrical ground and superior mechanical support.
-
Low PIM Engineering: Designed with non-magnetic materials and high-pressure contact points to ensure ultra-low PIM (≤ -155 dBc), which is vital for receiver sensitivity.
-
Field-Installable Clamp: The clamp mechanism allows for reliable, airtight assembly using standard wrenches, eliminating the need for specialized hydraulic tools.
-
Weatherproof Integrity: Rated for IP68 protection, ensuring a secure seal against rain, dust, and environmental oxidation in exposed locations.
-
High Power Handling: Capable of dissipating significant average and peak power, making it suitable for both macro and small-cell transmitter interfaces.
