Product information

Description

The InLine 92504K wire connector features a 3.5 mm 4-pin TRRS female jack and a 4-terminal block for secure audio and microphone signal routing. Designed with RoHS and TÜV compliance, this black and green adapter provides a reliable connection for custom wiring projects, audio equipment setups, and DIY electronic integrations. It allows solder-free connection of analog audio and microphone signals to screw terminals, making it a practical choice for headsets, combo plugs, and TRRS interfaces.

Advantages

This adapter saves time during installation through quick wiring via screw terminals for 18–26 AWG cables, supported by a flat-head screwdriver. It ensures precise contacting of audio and microphone signals using a clearly labeled terminal strip with L, R, V, and + assignments. The side terminal strip enables space-saving installation in limited areas such as test boxes or distribution panels. High signal quality is maintained through reliable insulation resistance and a rated current of up to 1 A per pin for continuous operation. Additionally, an EVA insulating layer on the underside offers extra protection when mounted on conductive surfaces.

Suitable for

  • Custom audio and microphone wiring projects
  • Connecting headsets and combo plugs to TRRS interfaces
  • Prototyping and testing in development laboratories
  • Integrating analog audio signals into control units and multimedia modules

When it may not be suitable

This adapter is not designed for permanent outdoor installation or environments exposed to moisture without additional weatherproof enclosures. It may also be unsuitable for high-power electrical transmission applications, as its maximum rated current is restricted to 1 A per pin.

Key specifications

  • 3.5 mm TRRS jack socket with 4 poles for stereo and microphone signals
  • 4-terminal block with screw connection and pressure plate
  • Compatible wire gauge: 18–26 AWG
  • Rated current: up to 1.0 A per pin
  • Maximum operating voltage: 100 V between signals
  • Insulation resistance: at least 10 MΩ at 300 V DC
  • Operating temperature range: -10 °C to +70 °C
  • Color: Black and Green
  • Dimensions: 23 x 36 x 12 mm
  • Weight: 9 g

How to use

To use the adapter, strip the insulation from your 18–26 AWG wires to expose the appropriate length of conductor. Insert the stripped wire ends into the corresponding screw terminals on the block, adhering to the labeled assignments for left channel, right channel, microphone or voltage, and ground. Secure each wire firmly by tightening the screws using a flat-blade screwdriver no larger than 2.5 mm. Once the wiring is complete, plug your 3.5 mm 4-pin TRRS cable into the female jack socket to establish the signal path.

What to consider before purchase

  • Verify that your equipment utilizes a standard 3.5 mm 4-pin TRRS connection
  • Check that your wire gauges fall within the 18–26 AWG range supported by the screw terminals
  • Ensure operating currents do not exceed the 1.0 A per pin limit
  • Confirm that the compact dimensions fit your intended installation space

Usage recommendations

Use the InLine wire connector strictly within specified voltage and current limits, and ensure proper cable strain relief in dynamic setups to prevent mechanical stress on the terminal block.
