L1M5-196LN-12 is a RG196 low noise 12 foot 50 ohm (3.66 meter) coax cable assembly with a L1 (Lemo 1 compatible) connector on one end and a 5-44 (mini-Microdot compatible) connector on the other end.

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". If you are looking for the smaller 0.25" diameter NIM/CAMAC connector, those are over here.

About M-Series Connectors

Click to enlarge There are multiple sizes of connectors which practitioners tend to call "Microdot". The most common size uses 10-32 threads, but there are also 5-44 and 1/4-32 variants, as shown in this image. This style of connector was pioneered by Malco in the late 1950's and early 1960's. Malco was later bought by Microdot, which was later bought by Tyco. Because of this history, users in the industries that use this connector style still call this a "Microdot connector", or even "Malco Connector", even though there are now multiple manufacturers making compatible connectors. "Microdot" is a trademark of Tyco. The connectors we provide are compatibles made by various manufacturers. They are often improved designs, mechanically more durable than the original Malco connector.

5-44 (M5) Connector Details These connectors have threads that are the same as those on a 5-44 (UNF) machine screw. They are commonly used on accelerometers, strain gauges, and NDT applications. They are commonly used in non-destructive testing (NDT) and aerospace, on transducers, accelerometers, and strain gauges, among other applications. The NDT industry often calls these "mini-Microdot" connectors.

About 50 ohm cable assemblies

About Low Noise Cable

Low noise cable is generally not recommended for RF use. In our own testing, we see characteristics which differ from ordinary cable, including phase delay and impedance variations with frequency. In the field, we've seen mixed results in the GHz range; low noise cables seem to provide the best results at signal frequencies in the low MHz or lower. Ultrasonic NDT, for example, uses low-noise cable with signals as high as 100 MHz, but in transient pulse trains, where phase delay is less critical. The results you get will depend on the application, and as always you will want to do your own testing before ordering large quantities.

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.
