MJ2135 - PCB Mount 4-Pole 3.5mm Phone Audio Connector Socket

The MJ2135 is a 4-pole 3.5mm PCB-mount audio socket designed for modern audio applications requiring stereo audio plus microphone or control signals, such as headsets, smartphones, tablets, and embedded audio devices.

This connector supports TRRS (Tip-Ring-Ring-Sleeve) 3.5mm plugs and is ideal for compact PCB designs where reliable signal integrity and mechanical stability are essential. The socket body is manufactured from PA66/CF resin, providing excellent mechanical strength, heat resistance, and durability for long-term use.

All internal contact components-including the tip, ring, and sleeve springs-are made from phosphor bronze (PBs) with silver (Ag) plating, ensuring low contact resistance, stable conductivity, and enhanced corrosion resistance. This makes the MJ2135 suitable for both consumer electronics and industrial audio applications.

Designed for direct PCB mounting, the MJ2135 offers secure solder connections and precise alignment, making it easy to integrate into audio circuits and compact electronic assemblies.
