InLine® 3.5mm jack socket 4-pin stereo/micro to terminal block
- Time savings during installation: Quick wiring via screw terminals for 18–26 AWG – tool-assisted with flat-head screwdriver ≤ 2.5 mm.
- Precise contacting of audio/microphone signals: 3.5 mm jack socket (TRRS, 4-pin) with clearly labeled terminal strip (L, R, V, +) – ideal for headset, audio, or control cables in test and prototyping setups.
- Side terminal strip for space-saving installation: Compact connection block with adjacent terminals – ideal for limited space, e.g., in test boxes or distribution panels.
- Versatile use in industry: For integrating analog audio signals into control units, multimedia modules, development labs, or test benches.
- High signal quality: An insulation resistance of ≥ 10 MΩ at 300 V DC and a rated current of up to 1 A per pin ensure reliable signal transmission – even in continuous operation.
The InLine® 3.5 mm 4-pin jack-to-terminal block adapter enables solder-free connection of analog audio and microphone signals to screw terminals – ideal for headsets, combo plugs, or TRRS interfaces in industry and laboratories.
The connections are clearly labeled:
L (left), R (right), V (microphone/voltage), + (common ground/shielding).
The screw terminals with a 5.0 mm grid size support 18–26 AWG wires and can be connected using a flat-blade screwdriver ≤ 2.5 mm.
Thanks to its compact design, the jack socket is particularly suitable for space-critical applications in test equipment, audio racks, or embedded systems. An EVA insulating layer provides additional protection when mounted on a conductive surface.
