InLine 92504J Conector de cabos ficha jack TRRS de 3,5 mm 4 polos / bloco de terminais 4 ligações, preto, verde

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: 4-pin 3.5 mm jack with assigned terminal strip (L, R, V, +) – ideal for audio, headset, or control cables in prototyping and test environments.
Side terminal strip for space-saving installation: Compact connection solution with adjacent screw terminal strip – ideal for narrow adapter panels or confined test environments.
Versatile industrial applications: For signal processing, control engineering, multimedia interfaces, or development laboratories with analog audio integration.
High signal quality:Insulation resistance ≥ 10 MΩ at 300 V DC and rated current up to 1 A – robust and suitable for continuous operation under industrial conditions.

The InLine® 3.5 mm 4-pin jack-to-terminal block adapter offers an easy way to wire analog audio and microphone signals without soldering. The 3.5 mm jack plug (TRRS) is directly connected to a 4-pin screw terminal block. The connections are clearly labeled: L (left), R (right), V (microphone/voltage), + (common ground or shielding) – ideal for signal splitting in headset or combo plug applications.
The screw terminals with a 5.0 mm pitch support wires in the 18–26 AWG range. Wiring is tool-assisted using a flat-blade screwdriver with a blade width ≤ 2.5 mm. The compact design allows for use in confined installation situations, e.g., in test setups, development laboratories, or audio interfaces. The EVA insulation layer provides protection when mounted on conductive surfaces.

How to use

Insert the 3.5 mm TRRS plug into the adapter jack and prepare conductors in the 18–26 AWG range. Loosen the screw terminals with a flat-blade screwdriver (blade width ≤ 2.5 mm), insert the stripped wire ends into the corresponding labeled terminals (L, R, V, +) and tighten the screws to secure the conductors. Verify connections and ensure the adapter is mounted on a non-conductive or EVA-protected surface to avoid shorts. Observe the rated current and operating voltage limits during use.

Recommendations

For reliable long-term performance, use stranded or solid copper conductors within the specified AWG range, avoid exceeding 1.0 A per pin, and keep the operating temperature between –10 °C and +70 °C. When installing in confined or metallic enclosures, ensure the EVA insulation layer is intact and properly positioned to prevent contact with conductive surfaces.
