PROEL S120 - 3.5mm Male Mono Mini Jack Connector with Metal Housing and Spring
The Proel S120 is a professional audio connector designed to offer maximum reliability and durability for your custom connections. Part of Proel's renowned S Series , this component stands out for its mechanical robustness and excellent conductivity, making it an essential piece for sound engineers, musicians, and electronics enthusiasts looking to repair or build their own signal cables.
Unlike conventional plastic connectors, the S120 features a robust nickel-plated brass construction, giving it a sleek silver finish and superior resistance to shocks and drops. Its clever design incorporates a flexible spring strain relief system, crucial for protecting the solder point and extending cable life by preventing common breakages from excessive pulling or bending.
Main features
-
Integral metal construction: Housing made of brass with a nickel finish, providing effective shielding and high resistance to physical wear.
-
Spring strain relief: Includes a flexible metal spring on the back that protects the integrity of the cable at the connector outlet, allowing smooth bends without damaging the inner core.
-
Standard 3.5mm Mono Format: Compatible with the vast majority of audio equipment that uses 1/8 inch TS (Tip-Sleeve) connections.
-
Easy assembly: Designed for clean and safe soldering, with accessible internal terminals that facilitate tinning and conductor fixing.
Product benefits
Choosing the Proel S120 connector guarantees clean, uninterrupted signal transmission. Its main advantage lies in its longevity ; thanks to its metal housing and protective spring, this connector withstands intensive use on stages, in studios, or in fixed installations much better than cheaper molded alternatives. Furthermore, its nickel-plated finish ensures excellent corrosion resistance, maintaining the quality of the electrical contact over time.
Use cases
-
Equipment repair: Ideal for replacing damaged connectors on lavalier microphones, control pedals, or old power supplies.
-
Modular Synthesizers (Eurorack): Perfect for manufacturing high-quality custom patch cables for modular systems that require TS mono connections.
-
Triggers and Sensors: Frequently used in cables for electronic battery triggers or infrared sensors that use this connection standard.
-
Fixed installations: Creation of custom cables for the integration of audio systems where a specific length and professional finish are required.
Frequently Asked Questions
Does this connector work for stereo headphones?
No, the Proel S120 is a mono connector (TS - Tip/Sleeve). If you use it with a stereo signal, it will either combine the left and right channels or mute one of them. For stereo headphones, you need a TRS (Tip-Ring-Sleeve) connector.
What cable thickness does the spring support?
The flexible spring is designed to accommodate cables with an outer diameter of up to approximately 5 mm . Thicker cables may not fit inside the spring, while very thin cables will work perfectly and remain protected.
Does it require welding?
Yes, this is a cable-mount connector. You will need a soldering iron and basic wire stripping tools to make the connection correctly.
