MSA-316DS-2 is a RG316 double shielded 2 foot 50 ohm (0.61 meter) coax cable assembly with a 10-32 (Microdot compatible) connector on one end and a SMA connector on the other end.

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.

10-32 (M) Connector Details These connectors have threads that are the same as those on a 10-32 (UNF) machine screw. They are commonly used in non-destructive testing (NDT) and aerospace, on transducers, accelerometers, strain gauges, and force and acoustic sensors, among other applications. These connectors are often confused with 1/4-32 connectors; they look similar, varying only slightly in size. If in doubt, check your mating connector using a thread gauge or caliper: 1/4-32 threads have a minor diameter of approximately 5.4 mm, while 10-32 threads have a minor diameter of about 3.9 mm. See a thread chart for more details.

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.
