2.5mm Audio Jack – Through Hole Right Angle Headphone Connector (DC 30V 1A)

This high-quality 2.5mm audio jack is a compact, reliable through-hole right-angle headphone and microphone connector designed for space-constrained PCB applications. Rated for DC 30V 1A, it delivers stable audio signal transmission for portable devices, communication equipment, medical instruments, consumer electronics, and industrial audio systems.

The connector features a durable PA66 insulation housing that provides excellent mechanical strength, thermal stability, and electrical insulation. The terminals are made from high-conductivity Phosphor Copper with gold (Au) plating, ensuring superior contact reliability, low signal loss, corrosion resistance, and extended mating cycles.

Available in multiple switch configurations to meet diverse circuit requirements:

• No Switch
• Tip Switch (TS)
• Ring Switch (RS)
• Tip & Ring Switch

These options allow designers to select the exact functionality needed for stereo audio, mono audio, microphone detection, or audio insertion detection.

This 2.5mm audio jack is engineered with identical dimensions, pin layout, mechanical tolerances, and electrical specifications as the popular CUI Devices (Same Sky) models SJ1-42514, SJ1-42515TS, SJ1-42515RS, and SJ1-42516. It serves as an excellent drop-in alternative, offering the same performance and PCB compatibility while providing a cost-effective sourcing solution.
