Between-Series RF Adapter: OSM (SMA) to TNC
The 1059169-1: Both ends are plug-style with male pin center contacts, and the adapter body is straight, meaning signal passes through without a right-angle bend. The conversion type is between series, so this is not a simple gender-changer — it transitions between two distinct connector families. The body is machined from stainless steel, providing mechanical strength and corrosion resistance for field-deployed cable assemblies. The dielectric is PTFE, the standard choice for maintaining consistent characteristic impedance and low insertion loss through the RF path. Both ends use threaded coupling, which gives a vibration-resistant connection — important when the adapter is part of a cable run subject to movement or equipment shock. The adapter is free-hanging (in-line), meaning it has no panel-mount flange and is intended to be spliced into a coaxial cable assembly.
What It Connects: SMA and TNC Interfaces
The convert-from end is a TNC plug with a male pin. The convert-to end is an SMA plug with a male pin. This means the adapter accepts a TNC jack (female) on one side and an SMA jack (female) on the other. It is compatible with standard SMA connectors — any SMA jack with a female center contact will mate directly with the SMA plug end. Similarly, any standard TNC jack will mate with the TNC plug end. The OSM designation in the adapter series is an older name for what is now universally called the SMA connector interface. The two are mechanically identical, so this adapter works with any standard SMA connector.
