SME 4-Pin Tonearm Connector | Turntable Headshell Plug Adapter

HUXUAN SME Standard 4-Pin Tonearm Connector for Turntable Headshell

Upgrade or restore your turntable's signal path with this precision-engineered SME-type 4-pin tonearm connector. Designed as a direct replacement for worn or damaged headshell adapters, this connector delivers a secure mechanical lock, stable electrical contact, and consistent audio signal transmission — all in a featherlight 5 g CNC aluminum alloy body. Made in Mainland China.

Why Choose This SME Tonearm Connector?

• Precision SME Standard Fit: 7.94 mm connector diameter engineered for accurate insertion into SME-type tonearms. An alignment notch prevents incorrect installation, ensuring a snug, wobble-free fit — no forcing or modification required.
• Stable 4-Pin Gold-Plated Contacts: Low contact resistance and reliable left/right channel separation help reduce signal loss, intermittent sound, and channel imbalance commonly caused by worn or poorly plated connectors.
• CNC Aluminum Alloy Construction: Precision-machined aluminum body with a durable, corrosion-resistant matte silver finish. The knurled grip ring makes installation and removal easy, even in tight spaces. Built for long-term use, not disposable swaps.
• Lightweight at Only 5 g: Minimal impact on tonearm effective mass maintains original tonearm balance and tracking characteristics — especially important for entry-level and mid-range tonearms with limited counterweight adjustment.
• Secure Anti-Rotation Locking Structure: Mechanical locking groove and alignment slot prevent rotation during playback, keeping electrical contacts stable and signal integrity intact at all times.

Frequently Asked Questions

Q: Is this SME tonearm connector compatible with all turntables?

A: This connector is designed specifically for SME-type tonearms that use the standard SME bayonet-style 4-pin interface with an inner diameter of approximately 8.0 mm. It is not a universal fit — please verify your tonearm uses the SME standard interface before purchasing.

Q: Will this 5 g connector affect my tonearm's tracking or balance?

A: At just 5 g, this connector is engineered to have minimal impact on tonearm effective mass. It is designed to maintain your tonearm's original balance and tracking characteristics, making it suitable for entry-level through mid-range tonearms with limited counterweight adjustment.

Q: Do the gold-plated contacts actually improve audio quality?

A: Gold-plated contacts offer lower contact resistance and improved corrosion resistance compared to bare metal alternatives. This helps maintain stable signal transmission, reduces channel imbalance, and minimizes signal loss — contributing to cleaner, more consistent audio output from your turntable.

Q: How many connectors are included in the package?

A: Each purchase includes one (1) SME 4-pin tonearm connector. If you require multiple connectors for a project, please order the appropriate quantity.
