DELOCK panel-mount 3.5 mm 4-pin female-to-female jack, gold-plated, black (91223)

The DELOCK panel-mount 3.5 mm 4-pin female-to-female jack is a compact panel connector designed to extend or join 4-pin 3.5 mm audio lines through equipment enclosures. Its gold-plated contacts provide improved conductivity and resistance to corrosion, while the black housing is intended for visible panel installation in audio equipment, intercoms or custom installations. The jack accepts standard 3.5 mm 4-pin plugs and provides a secure, low-profile interface for signal transfer in tight spaces.

Advantages

This panel-mount jack offers reliable electrical contact due to gold-plated terminals, reducing the risk of signal loss or oxidation over time. The female-to-female configuration simplifies panel-to-panel or panel-to-cable extensions without requiring soldering of internal wiring. Its compact form factor and panel-ready design enable neat installations and easy replacement in repair or upgrade scenarios.

Suitable for

• Joining two 3.5 mm 4-pin audio connectors across a panel
• Panel mounting in intercoms, communication devices, or custom-built equipment
• Repairing or extending existing 4-pin audio cabling without modifying internal circuitry
• Compact installations where space for connectors is limited

When it may not be suitable

This jack is intended for 3.5 mm 4-pin audio connections; it is not suitable for other connector types or for applications requiring different pin counts. It is a passive mechanical connector and does not provide signal conversion, amplification, or shielding beyond the inherent properties of its materials. For environments requiring high-level mechanical strain relief, IP-rated sealing, or specialized locking mechanisms, an alternative connector type may be preferable.

Key specifications

• Connector type: 3.5 mm (1/8") 4-pin female-to-female panel-mount jack
• Contact plating: gold-plated contacts for improved conductivity and corrosion resistance
• Mounting: panel installation with a bezel suitable for visible mounting
• Housing color: black
• Compatibility: accepts standard 3.5 mm 4-pin male plugs used in audio and communication devices

How to use

Prepare a suitably sized mounting hole in the equipment panel according to the jack's mechanical dimensions and insert the jack from the front. Secure the jack to the panel using the provided nut or fastening method and ensure the housing is flush and stable. Connect the external 3.5 mm 4-pin male plugs to each side of the female-to-female jack to extend or join audio lines. Verify correct seating of plugs and check audio continuity after installation.

What to consider before purchase

• Confirm that your cables and devices use a 3.5 mm 4-pin configuration (not stereo 3-pin or other pinouts)
• Ensure the panel cutout dimensions in your equipment match the jack's mounting requirements
• Consider whether gold-plated contacts are needed for your environment (humidity, oxidation risk)
• Check that a passive, non-locking female-to-female jack meets your mechanical retention needs

Usage recommendations

Use the jack for straightforward panel extensions and repairs in audio and communication equipment, and inspect connectors periodically for secure seating and corrosion if used in humid or corrosive environments.
