PROEL S232S - 6.3 mm Stereo TRS Jack Connector with Gold-Plated Contacts and Spring Protection
The Proel S232S is a 6.3 mm (1/4") stereo jack connector designed for maximum reliability in professional audio environments. Part of Proel's renowned connector series, this model stands out for its extremely robust mechanical construction combined with highly conductive components, ensuring clean and uninterrupted signal transmission.
Unlike generic connectors, the S232S features a nickel-plated metal (brass) housing that protects the internal solder joints from impacts, being stepped on, and everyday wear and tear on stages or in studios. Its most distinctive feature is the inclusion of a flexible strain relief spring on the back. This steel spring protects the cable at its most vulnerable point (the connector outlet), preventing excessive bending and internal breakage that often cause noise or signal dropouts after prolonged use.
The audio quality is guaranteed thanks to its gold-plated contacts . This finish isn't just for looks; gold provides superior resistance to oxidation and corrosion, ensuring a perfect electrical connection for years, even in humid environments. It's the ideal choice for technicians, musicians, and installers who need to make their own balanced or stereo cables to a superior standard.
Main features
-
Professional Standard Format: 6.35 mm (1/4 inch) male jack connector compatible with any standard stereo or balanced input or output.
-
TRS (Tip-Ring-Sleeve) configuration: Designed for stereo (left/right) or balanced mono (+/-/ground) signals.
-
Gold-Plated Contacts: Improves electrical conductivity and prevents corrosion, eliminating noise from poor connections.
-
Rugged Metal Housing: Nickel-plated brass body with a bright silver finish, designed to withstand the usual abuse on tours and in studios.
-
Integrated Cable Protection: Flexible helical spring on the back that acts as a strain relief, accommodating cables up to 7 mm in diameter (approx.).
-
Ergonomic Solder Terminals: Optimized internal design for easy tinning and secure conductor attachment.
Product benefits
-
Cable Longevity: The rear spring absorbs mechanical stress, preventing the cable from snapping right where the connector ends, which is the number one cause of instrument cable failures.
-
Crystal Clear Signal: Thanks to the gold plating, contact resistance is minimized, resulting in pure audio transmission, without loss of high frequencies or introduction of distortion.
-
Connection Versatility: Being a TRS connector, a single model can be used both to repair high-end headphones and to manufacture balanced line cables for studio monitors.
-
Professional Appearance: Its metallic finish and classic design offer a polished, high-end aesthetic, ideal for visible studios or permanent installations.
Use cases
-
Balanced Cables: Making cables to connect audio interfaces to studio monitors (balanced signal).
-
Headphone Repair: Replacing damaged connectors on studio or Hi-Fi headphones that use a large plug.
-
Insert Connections: Manufacturing of "Y" cables for mixing consoles that use a single jack for send and return.
-
Stereo Instruments: Connection of keyboards, synthesizers or effects pedals that have stereo output in a single jack.
-
Fixed Installations: Use in patch panels and patchbays where durability and zero maintenance are required.
Frequently Asked Questions
-
Does this connector work for a standard guitar cable?
Yes, it physically fits, but for a standard guitar (which is mono), the S232 (without the final "S") or S230 model is recommended. If you use this S232S model on a guitar, you'll need to leave one pin unconnected or bridge it, but ideally, for mono instruments, you should use a TS (mono) connector. This model is TRS (Stereo/Balanced).
-
What is the maximum cable diameter it accepts?
The flexible protective spring has an approximate inner diameter of 7.3 mm, making it ideal for standard audio cables between 6 mm and 7 mm.
-
Is it difficult to weld?
No. The internal terminals of the Proel connector are well-spaced and accept solder well. However, being a TRS (three-pole) connector, it requires slightly more precision than a single-pole connector. Basic soldering experience is recommended.
-
Does the casing unscrew?
Yes, the metal casing unscrews to access the soldering points and slide the protective sleeve over the cable before soldering.
