L00M-174-5 is a 50 ohm RG174 5 foot cable with a Lemo 00-compatible connector on one end and a 10-32 (Microdot-compatible) connector on the other end.

RG174 alternate designations: RG-174 RG174A/U RG-174A/U

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.
• Belden 9239 low noise RG174 cable available -- see Cables/RG174 low noise.
• RoHS compliance available upon request.

10-32 (Microdot-compatible) Connector Detail: These connector threads are the same as those on a 10-32 (UNF) machine screw. Practitioners in the ultrasonic and eddy current NDT industry, including the aerospace, petroleum oil, gas production, thin-film and wafer inspection segments, tend to call these "Microdot" connectors, but there have been many connector models, of various shapes and sizes, made under the Microdot name. (Microdot Inc. has since been acquired by Tyco; the Microdot trademark registration expired in 2004, though the company still does business under that mark.) Several industries and applications tend to instead call these "10-32" connectors; you will often find this designation on velocity sensors and accelerometers, force sensors, acoustic sensors, various piezoelectric applications, radio (RF) and WiFi tranceivers, and professional audio lapel microphones, to name a few.

About Hi-Pot Testing

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.
