Circular Connector Details

Circular connectors, also called "push-pull" or "quick connect/disconnect", are commonly used in non-destructive testing (NDT), physics, and aerospace, on transducers, flaw detectors, and other applications.

This style of connector was pioneered several decades ago by the Swiss connector manufacturer LEMO. Because of this history, practitioners in the industries that use this connector style still tend to call this a "LEMO connector", even though there are now multiple manufacturers making compatible connectors. "LEMO" is a registered trademark of LEMO USA.

We source our connectors from multiple vendors. The connector we provide to you may be made by LEMO, or may be a compatible model from an aftermarket manufacturer. If you have a preference, please feel free to contact us for a quote.

Our circular connectors come in two different sizes. The L1 connectors have a diameter of roughly 0.5". The L00 connectors have a diameter of roughly 0.25", and are often used in physics and engineering applications for interconnection between NIM/CAMAC modules. For further reference, see:

About 50 ohm cable assemblies

This cable assembly has a characteristic impedance of 50 ohms. 50 ohm coax cable, connectors, and adapters are commonly used in GPS and wifi (802.11 wireless LAN) antennas, ham transceivers, and other radio frequency (RF) analog and digital signaling, microwave, radar, hi-fidelity professional audio, non-destructive testing (NDT), oil and petroleum production, ultrasonic transducers, accelerometers, strain gauges, and some professional video applications.

About Low Loss Cable

This is Belden's 7805 "low loss" cable. It's similar to RG174, but with a solid copper core and a layer of foil added under the braid. This combination causes less attenuation, providing roughly 50% more signal as measured in decibels. 7805 also works better at higher frequencies, and is rated up to 6 GHz. The foil layer also provides for better EMF shielding versus braid alone.

We see this cable used in fixed-place permanent installations such as wifi and GPS antenna extensions, other RF applications, low-voltage signal sources including radiation detectors and strain gauges, high-frequency or fast-rise transient signals, and other low-vibration applications in aerospace, nuclear physics, petroleum refining and chemical processing.

This cable is not recommended for use in applications where it will undergo repeated cycles of flexing or vibration -- the solid core will eventually break under those conditions. You may instead want one of these stranded-core RG174 variants:

RG174 standard has a stranded core and PVC jacket.
RG174 TPR has a stranded core and TPR jacket. The TPR jacket provides for more flexibility, most useful in bench and handheld applications.
RG174 low noise has a stranded core, PVC jacket, and a carbon layer under the braid. The carbon layer reduces flexing-induced static and provides some additional shielding. It's best at lower frequencies -- see the notes on that page.

We hi-pot test our cable assemblies for high-voltage breakdown between core and braid. See About Hi-Pot Testing for why this might matter to you, particularly for physics or NDT applications. Caution: We make no claims as to the safety of this product for high-voltage use. These voltages can kill. Do not handle or approach any cable or conductor carrying high voltage; this includes insulated cables, nearby metal parts, water, and other conductive materials. Engineering and design for safety in your application are your responsibility.
