L1S2C-174TPR-40 is a RG174 flexible (TPR jacket) 40 foot 50 ohm (12.2 meter) coax cable assembly with
a L1 (Lemo 1 compatible) connector
on one end and
a SSMC 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 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.
This cable has a thermoplastic rubber (TPR) jacket (also known as
thermoplastic elastomer or TPE). This material is softer and more
flexible than a standard PVC cable jacket, even at low temperatures.
TPR is resistant to petroleum oils, many chemicals, ozone, and other
environmental contamination sources. TPR-jacketed cables weather well
and are abrasion-resistant. They are not cut-resistant or built to
withstand longitudinal tension, so should not be buried or used in
umbilical tether applications without additional protection.
You've likely seen TPR before -- it's the high-friction, rubbery
material used as the jacket for many test bench leads and patch
cables. The flexibility makes TPR-jacketed cables popular for use
with handheld sensors and probes; we see them used a lot with
ultrasonic contact transducers and eddy current probes. The
flexibility and small bend radius of these cables makes them ideal for
use with microphones, DF antennas, and other handheld or wearable
devices, in robotic or mechatronic remote control and telemetry,
automated or CNC machines, and precision motion control. Popular
outdoor uses include flightline, oil rig, pipeline inspection, arctic,
and other extreme environment applications where flexibility at low
temperature is important.

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.
