MJ-073H – PRO SIGNAL

The MJ-073H, manufactured by PRO SIGNAL, is a 3.5mm (1/8″) audio jack designed for panel mounting. This is a three-pole (TRS) connector, indicating support for stereo audio signals plus a ground return. The jack accepts standard 3.5mm plugs conforming to the TRS configuration, enabling connection of headphones, microphones, and other audio devices. Electrical characteristics, such as contact resistance and insulation resistance, are not specified in the provided information and must be determined through independent testing or by consulting the manufacturer’s full datasheet. The mechanical design facilitates secure retention of inserted plugs via internal spring contacts. The three poles are typically configured as Tip (Left Channel), Ring (Right Channel), and Sleeve (Ground). The specific materials used in the construction of the housing and contacts, as well as current and voltage ratings, are not provided and require further investigation.
