The Microdot 10-32 right-angle plug for RG316 is the 50 Ω subminiature coaxial connector that terminates RG316 or RG174 sensor leads with a 90-degree exit, keeping the cable low and out of the way where there is little headroom above the instrument. Its 10-32 UNF threaded coupling — the interface engineers simply call "Microdot" or "M5" — is the de-facto standard fitted to piezoelectric and IEPE accelerometers and to dynamic pressure and force transducers from makers such as PCB Piezotronics, Dytran, Endevco, Kistler and Bruel & Kjaer. The threaded coupling is the point: it cannot shake loose under the vibration these instruments are built to measure, and the right-angle body adds clearance without giving that up.

Microdot 10-32 is the established interface across vibration and modal testing, machine condition monitoring, bearing and rotating-machinery diagnostics, NDT and ultrasonic flaw detection, acoustic emission, and aerospace and automotive instrumentation. The right-angle exit earns its place wherever an accelerometer sits under a cover, inside a housing, or close to an adjacent fixture: the lead turns immediately at the connector rather than standing proud, which protects the cable from snagging and reduces strain at the joint. On RG316, the PTFE dielectric also gives wider temperature tolerance and better mechanical durability than PVC-jacketed coax, suiting test rigs and engine or powertrain work where the lead sees heat or repeated flexing.
In assembly the centre conductor solders into a slot in the contact and a cap is fitted over the body to complete the right-angle joint; the cable is crimped at the ferrule. Cable-strip figures are not quoted here because the supporting RFShop documents disagree on the exact strip lengths — follow the dimensions printed on the datasheet that ships with the part, and prepare the braid clean and untwisted. The plug mates with any standard 10-32 Microdot jack, the socket fitted to most IEPE and piezoelectric accelerometers and transducers.
Need a straight version instead of right-angle, the same connector on flexible RG174 for lighter routing, or a finished lead rather than loose parts? See the full Microdot sensor & instrumentation range, order it pre-fitted to a custom cable, or check which connector fits which cable if you are unsure of your coax.
