About Audio Connectors

3.5mm phone jacks remain the universal interface for consumer and industrial audio connectivity. Their compact size and standardized plug compatibility simplify audio signal routing in space-constrained designs.

Female jacks with switching functionality enable features like plug detection or source switching. Right-angle versions (like the SJ1-3525NG) optimize PCB layout efficiency in flat-profile devices while maintaining mechanical strain relief.

Packaging

Supplied in protective trays to prevent damage during shipping and handling. Contact PCX for bulk order options.

FAQs

Q: Is this compatible with standard 3.5mm headphone plugs?
A: Yes, it accepts industry-standard 1/8″ (3.5mm) TRS/TRRS mini plugs.

Q: What is the purpose of the two internal switches?
A: Switches enable functions like plug detection, audio source switching, or circuit interruption upon insertion.

Q: Can this handle microphone signals?
A: While designed for stereo audio, it supports mono signals. For TRRS (mic+stereo), verify pin compatibility with our datasheet.

Q: Is the housing RoHS compliant?
A: Yes, all Same Sky connectors meet RoHS environmental standards.

Q: What’s the difference between TRS and TRRS?
A: TRS has 3 conductors (stereo audio). TRRS adds a fourth conductor for microphones or video.

Q: Can I mount this on 1.6mm PCBs?
A: Yes, the through-hole design supports standard PCB thicknesses. Refer to the datasheet for footprint details.
