WQP-WQP518MA Qingpu 3.5mm Eurorack TS Mono Jack PC Pin

Introducing the industry-standard Qingpu WQP-WQP518MA Eurorack TS Mono Jack, the epitome of quality and reliability for both DIY and professional Eurorack projects. Engineered for precision and durability, this is the most commonly used 3.5mm switched-tip mono jack for Eurorack, distinguished by several key technical advantages:

• Superior Contact Material: The tip contact is constructed from Beryllium Copper (BeCu), offering enhanced elasticity and durability over standard phosphor bronze. A specialized heat treatment process optimizes the BeCu's mechanical properties, ensuring the switch mechanism remains reliable and avoids material failure. This design has been rigorously tested to surpass 20,000 cycles, far exceeding the typical 5,000-cycle life expectancy of similar components.

• Anti-Rotation Bushing: A proprietary square bushing design prevents the jack's body from turning within its mounting hole, even when subjected to high torque from the fastening nut. This ensures a secure and stable installation every time.

• Optimized Internal Structure: The geometry of the tip and the length of the static contact are precisely engineered to ensure a perfect mechanical and electrical interface. This contributes to a stable, low-resistance connection and consistent switch performance for all your CV needs.
