Times Microwave SZ-240-TM TNC Male Connector

Times Microwave SZ-240-TM TNC Male Non-Solder Crimp Connector (LMR-240)

The Times Microwave Systems SZ-240-TM (Stock Code: 3190-2582) is a high-performance 50-Ω TNC straight male (plug) RF coaxial connector engineered specifically for 240-size low-loss flexible coaxial cables, including LMR-240, LMR-240-UF, and TCOM-240. Belonging to Times Microwave's Spring-Finger (SZ/EZ) series, it utilizes a solderless captive spring-finger center pin along with a crimp outer ferrule. This configuration eliminates assembly errors, cold solder joints, and heat damage to the cable's foam dielectric.

Constructed with an Alballoy-plated brass body (Copper-Tin-Zinc alloy) for high corrosion immunity, a gold-plated beryllium copper pin, and PTFE (Teflon) insulation, the SZ-240-TM operates reliably up to 6 GHz with low VSWR. The threaded TNC coupling interface provides weather-tight mechanical retention that resists severe hull vibration, engine harmonics, and thermal cycling in marine and offshore installations.

Key Features

• Solderless Center Pin Assembly: Captive beryllium copper spring-finger pin eliminates soldering, reducing assembly time and preventing thermal degradation of cable insulation.

• High Vibration Resistance: Threaded TNC coupling interface prevents loosening and signal intermittent disconnects under severe vessel hull pounding.

• Alballoy Tri-Metal Body Plating: Offers non-magnetic, corrosion-resistant surface protection superior to standard nickel plating in harsh marine salt-air environments.

• Low Loss up to 6 GHz: Precision-machined 50-Ohm architecture maintains low VSWR and stable signal integrity across VHF, UHF, Cellular, GPS, and Wi-Fi marine frequencies.
