SAA or 1.0/2.3 M Solder Type for LMR240 Cable

Description

The SAA series, universally known as the 1.0/2.3 connector, is a subminiature RF interface designed to maximize port density in modern telecommunications environments. This male (plug) solder-type variant is specifically adapted for LMR240 coaxial cable, which offers lower attenuation than standard micro-cables while maintaining flexibility. Unlike standard crimp versions, the solder-type center contact provides a fused, low-resistance electrical bond, ensuring maximum signal transparency for high-capacity digital circuits (E1, E3, DS3) and professional video applications.

Maintaining a strict 75-Ohm impedance, this connector is vital for preventing signal reflections and bit errors in high-speed data transmission. The push-pull coupling mechanism allows for quick, tool-free mating with a secure tactile “lock,” enabling rapid deployment in high-density equipment racks. Manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation, it delivers exceptional electrical stability and superior protection against environmental oxidation, even in demanding central office or broadcast exchange environments.

Key Technical Advantages

• Permanent Solder Termination: The solder-cup center contact provides a high-conductivity fused connection, offering superior electrical permanence and lower contact resistance compared to standard crimp pins.

• LMR240 Low-Loss Integration: Specifically calibrated for the dimensions of LMR240 cable, allowing for longer cable runs with reduced signal degradation compared to micro-diameter cables.

• Ultra-High Density Footprint: The compact 1.0/2.3 interface allows for significantly higher port density on equipment panels than traditional 75-Ohm connectors like BNC or SMZ.

• Push-Pull Coupling Mechanism: Features a secure, vibration-resistant mating system that provides a distinct tactile click, ensuring a complete and reliable electrical path without the need for tools.

• Superior Corrosion Protection: Premium gold-over-nickel plating on all critical surfaces ensures long-term durability and low contact resistance in professional infrastructure.

Key Features

• Interface Type: SAA / 1.0/2.3 Male (Plug) with 75-Ohm impedance.

• Termination Method: Solder center contact with a high-strength outer crimp ferrule for mechanical strain relief.

• Cable Compatibility: Optimized for LMR240 and compatible low-loss 75-Ohm coaxial cables.

• Premium Construction: Features a gold-plated brass body and a high-performance PTFE dielectric for thermal stability during soldering.

• Industrial Application: Ideal for high-density Digital Distribution Frames (DDF), telephony racks, and modular broadcast exchange equipment.
