L1SA-196LN-50 is a 50 ohm RG196 low noise 50 foot cable with
a Lemo 1-compatible connector
on one end and
a SMA connector
on the other
end.
RG196 alternate designations: RG-196
This cable has a conductive PVC layer added around the polyethylene
dielectric; this layer helps to increase shielding, dissipate static
charge, and reduce mechanically-generated electrical noise as the
cable is flexed. This extra protection is useful for long cable runs,
low-voltage signals, high-vibration environments, in applications
including aerospace, automotive, NDT, DX ham radio, strain gauges and
accelerometers, and extremely high fidelity professional audio and
video production.
This cable assembly has a
characteristic
impedance of 50 ohms.
50 ohm cable, connectors, and adapters are commonly used in wifi
(802.11 wireless LAN) antennas, ham tranceivers, 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.

Cable Features:
- Our mass-produced cables are manufactured in our own
facilities; our custom-made cables are handcrafted by
experienced specialists in the heart of Silicon Valley.
- We hi-pot (high voltage) test our cable assemblies to 1500V
(low noise to 500V, SMA and SMB to 1000V). See About Hi-Pot Testing
below for why this might matter to you, for both high and low-voltage
applications.
If you plan to use
this cable in a high-voltage application, please read the
safety-related caution in that section.
- RoHS compliance available upon request.
About Hi-Pot Testing
High-power applications can cause cables to fail if the cables aren't
built right. High transmit power in radio, or composite materials,
air-coupled scanning, and other high power domains in nondestructive
testing, can cause radio transmitters or NDT pulser-receiver equipment
to drive antennas or ultrasonic transducers with energies that can
exceed 1000 volts. But the connectors made for small-diameter cable
are typically designed and rated by manufacturers for as little as 30
volts. Too often the result is arcing, dielectric breakdown, poor
signal performance, and in most cases an eventual total cable or
connector failure, as carbon traces build up and cause a short between
conductors. But entire industry segments use these low-voltage
components anyway, often for historical reasons dating back to times
when power demands were not as high.
The same defects which cause high-voltage breakdown can cause
problems in low-voltage applications as well. Contamination or
air-gap issues affect the cable's impedance at the point where the
defect exists, causing internal reflections, leading to signal loss,
noise, and, in extreme cases, damage to transmitter circuitry.
In order to prevent this and other mishaps from happening to you, we
test to destruction when selecting suppliers and connector designs.
During assembly, we use techniques and materials that we've evolved
over time to greatly improve the voltage-carrying capacity of these
parts. Before shipping, we test each and every cable assembly we
build -- we don't simply pull a few out for an audit check. Even with
this added cost in our manufacturing process, we still ship some of
the least-expensive cables in the industry, and we're content knowing
that these cables will perform reliably in the field.
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. The hi-pot test results
mentioned here are not an indicator of human, animal, or
equipment safety around these cables when carrying high voltage. We
do not test for high-voltage breakdown of the external
insulating jacket, and field conditions can easily contaminate or
damage the outside jacket and its insulating capacity. In a
high-voltage application, you should ensure that you are using the
braid for earth ground -- though that alone is not enough to ensure
safety. When we work with these voltages, we take extensive safety
precautions, and you need to as well.
