Frequently Asked Questions
How many contacts does STX-3680-5NB have and what audio configurations does it support?
STX-3680-5NB features 5 contacts, accommodating a 3.5 mm TRS or TRRS plug. The 5-contact design supports stereo audio (left and right channels at approximately 1 V RMS) plus one or more switching contacts for headphone insertion detect or microphone channel routing, making it suitable for 4-pole headset jacks.
What mounting style does STX-3680-5NB use and how does that affect mechanical durability?
STX-3680-5NB uses through-hole mounting, which anchors the 3.5 mm audio connector body to the PCB via soldered pins. This provides significantly higher pull-out force resistance than surface-mount alternatives, typically withstanding more than 10 N of cable strain before mechanical failure, making it preferable in handheld devices subject to repeated cable insertion.
For a headset combo jack design, why would STX-3680-5NB be chosen over a 3-contact 3.5 mm connector?
STX-3680-5NB provides 5 contacts versus the 3 contacts of a standard TRS jack, adding switching contacts that can detect headphone insertion and route microphone signals without requiring an external detection circuit. This reduces BOM count and PCB area in headset combo jack applications while maintaining the standard 3.5 mm plug interface compatible with headphones and headsets worldwide.
Which professional audio or industrial voice applications benefit from Kycon STX-3680-5NB?
STX-3680-5NB is used in professional audio mixers, field recorders, industrial intercoms, and voice communication terminals requiring a 3.5 mm audio interface rated for frequent cable connections. The through-hole construction withstands repeated mating cycles and provides the mechanical stability needed in rack-mount equipment and handheld radio accessories operating across -40°C to +85°C environments.
