Cable gender changer InLine 92504K — audio/video adapter, model 92504K

The InLine 92504K adapter is a 3.5 mm TRRS (4‑pole) jack to screw terminal block that enables solder‑free connection of analog audio and microphone signals. It converts a 3.5 mm TRRS plug into four clearly labeled screw terminals (L, R, V, +) and is designed for compact, space‑saving installations in test equipment, development labs, multimedia modules, and control units. The underside has an EVA insulating layer for mounting on conductive surfaces.

Advantages

Quick wiring via screw terminals supports 18–26 AWG and is tool‑assisted with a flat‑head screwdriver up to 2.5 mm, saving time during installation. Clear terminal labeling (L, R, V, +) ensures precise contacting of audio and microphone signals for headsets, combo plugs or TRRS interfaces. The side terminal strip and compact housing allow installation in limited space while maintaining high signal quality with insulation resistance ≥ 10 MΩ at 300 V DC and a rated current up to 1.0 A per pin.

Suitable for

• Connecting headsets or TRRS combo plugs to test benches and prototype setups
• Integrating analog audio signals into control units or multimedia modules
• Temporary or bench connections in development and repair labs
• Space‑constrained installations in distribution panels or audio racks

How to use

Insert a 3.5 mm TRRS plug into the jack socket and connect stripped wires (18–26 AWG) to the corresponding screw terminals labeled L (left), R (right), V (microphone/voltage) and + (ground/shield). Secure each conductor with the screw terminal using a flat‑blade screwdriver (≤ 2.5 mm). Ensure correct wiring and tighten screws to obtain reliable contact; do not exceed the rated current and voltage.

Usage recommendations

For best signal reliability, use copper conductors within the specified AWG range, avoid excessive bending at the connection points, and mount the adapter on a non‑conductive surface or rely on the EVA insulation if mounting on conductive surfaces. Verify wiring assignments before powering connected equipment.
