Cable gender changer InLine 92504J — audio/video connector adapter

The InLine 92504J cable gender changer is a compact 3.5 mm TRRS jack-to-terminal block adapter that lets you wire analog audio and microphone signals without soldering. The TRRS 4-pin jack is directly connected to a 4‑pole screw terminal block with clearly labeled contacts: L (left), R (right), V (microphone/voltage) and + (common ground/shield). The adapter supports quick wiring in confined installation spaces such as test setups, development laboratories, or compact AV interfaces and provides EVA insulation on the underside for mounting on conductive surfaces.

Advantages

Time is saved during installation thanks to screw terminals that accept 18–26 AWG and are tool-assisted using a flat-head screwdriver with blade width ≤ 2.5 mm. The side-mounted terminal strip enables space-saving installation on narrow adapter panels. The design maintains high signal quality with insulation resistance ≥ 10 MΩ at 300 V DC, a rated current of up to 1.0 A per pin and a maximum operating voltage of 100 V between signals, making it suitable for continuous use in industrial or laboratory environments.

Suitable for

• Prototyping and test environments for audio/headset wiring
• Development laboratories and engineering test benches
• Multimedia interfaces and compact AV installations
• Temporary connections, repairs, and signal splitting for headsets or combo plugs

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.

Usage 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.
