Description
The MA3MJ3 is a rugged metal adapter connector engineered to bridge 3-pin XLR male connections to standard 6.35mm (1/4″) female jacks. Built with a durable zinc die-cast shell, this adapter delivers dependable signal transfer for professional audio applications where equipment interfaces don’t natively match. With gold-plated copper alloy contacts, low contact resistance, and a secure latch-lock mechanism, the MA3MJ3 is designed for musicians, audio engineers, and AV technicians who need a reliable, long-lasting connection solution in live sound, studio, and installation environments. Its compact 89.1mm body and precision-machined construction ensure a snug, secure mate that withstands repeated use.
Key Features
- XLR-to-1/4″ Conversion: Converts a 3-pin XLR male connector to a standard 6.35mm female jack, enabling quick compatibility between mismatched audio gear.
- Zinc Die-Cast Shell: A strong, impact-resistant metal housing (ZnAl4Cu1) provides long service life and high mechanical reliability.
- Gold-Plated Contacts: Copper alloy contacts with gold plating ensure low contact resistance (≤3mΩ inner, ≤6mΩ outer) and stable, corrosion-resistant signal transfer.
- Secure Latch Lock: An integrated latch-locking mechanism keeps the connection firmly seated, preventing accidental disconnects during use.
- High Dielectric Strength: Rated at 1.5kVdc (XLR side) and 1kVdc (jack side), safeguarding against electrical breakdown under normal operating conditions.
- Excellent Insulation: Insulation resistance greater than 2GΩ minimizes signal leakage and interference.
- Extended Mating Life: Rated for more than 1,000 mating cycles, supporting frequent connect/disconnect use in touring or rental environments.
Material and Environmental Specifications
- Contact Material: Copper alloy (Cu alloy) contacts for reliable conductivity.
- Contact Plating: Gold (Au) plating resists oxidation and maintains consistent signal quality over time.
- Insert Material: Glass-fiber reinforced polyamide (PA66 + 30% GF) for a rigid, heat-resistant internal structure.
- Shell Material: Zinc die-cast alloy (ZnAl4Cu1) for a tough, durable outer housing.
- Shell Plating: Chrome (Cr) finish for a polished appearance and added corrosion resistance.
- Protection Class: Rated IP40, offering basic protection against solid foreign objects and accidental contact.
- Operating Temperature Range: -20°C to +65°C, suitable for a wide range of indoor and semi-outdoor environments.
Design and Build Quality
- Compact Form Factor: An overall length of 89.1 ± 0.2mm and outer diameter of Ø30.2mm keep the adapter easy to handle without adding bulk to cable runs.
- Precision Manufacturing: Tight dimensional tolerances ensure consistent fit and function across production batches.
- Professional-Grade Finish: The polished chrome-plated shell gives the connector a premium look suited for professional audio equipment.
