🎯 What a “Stereo Socket” (TRS) really is • There is a widely used standard called the “phone connector (audio)” family — plugs & sockets originally used in telephone switchboards, now common for headphones, audio cables, instruments, etc.  • The version that carries stereo sound (left + right) uses 3 contacts — known as “Tip-Ring-Sleeve” (TRS). The contacts correspond to: • Tip → Left audio channel • Ring → Right audio channel • Sleeve → Ground / return reference  • The socket is the female end (jack), into which the male plug (with tip/ring/sleeve) is inserted. Typical Uses & Form-factors • Standard versions: 3.5 mm mini-jack (common in phones, laptops, MP3 players) and 6.35 mm (¼″) jack (used in guitars, pro audio gear, headphones, amplifiers)  • On PCBs or inside devices you might find panel-mount or PCB-mount stereo sockets, often made of plastic + metal contacts. They let you plug in external stereo plugs to route audio signals.  • In many such sockets, there might be internal switching contacts: when no plug is inserted, certain pins are connected (e.g. to built-in speakers), but when a plug is inserted, those internal connections break and signal is rerouted to the plug — that’s how many headphone-sockets mute internal speakers automatically.  ✅ What I conclude about “STEREO2-3RC socket” • There is no recognized standard or datasheet publicly available under the exact label “STEREO2-3RC socket.” • The closest, functioning relevant hardware is a 3-pole stereo socket (female jack), sometimes referenced simply as “stereo socket” or “3.5 mm stereo jack socket.” • If you saw “2-3RC” in documentation or a catalog — likely it’s either a mis-print or proprietary part-code, not a standard designation. If you want, I can pull up 5–10 example stereo socket datasheets (with schematics, pinouts, mounting types) — that helps ensure you get exactly what you need rather than chasing ambiguous labels.
