Description
The MA3M3M is a circular metal adapter engineered for professional audio applications, converting a 3-pin XLR male connector to a 3-pin XLR male connector. Built with a rugged zinc alloy housing, the adapter delivers long-term durability and consistent electrical performance, making it suitable for use in live sound, broadcast, and studio environments where reliable signal continuity is essential.
Key Features
- Circular Metal Construction: A robust circular metal body provides a compact, durable form factor for demanding professional use.
- 3-Pin XLR Male to Male: Enables direct male-to-male XLR connections, ideal for converting or extending existing cable runs.
- Zinc Alloy Housing: Rugged zinc alloy housing ensures long service life and high reliability under repeated use.
- Low Contact Resistance: Contact resistance of ≤3 mΩ supports stable, low-loss signal transmission.
- High Dielectric Strength: Rated at 1.5 kV DC dielectric strength for safe, reliable electrical isolation.
- Smooth Mating Action: Insertion and withdrawal forces of ≤20 N allow for easy, controlled connection and disconnection.
- Long Service Life: Rated for over 1,000 mating cycles, ensuring dependable performance over time.
Material and Environmental Specifications
- Contacts: Made from copper alloy for excellent conductivity.
- Contact Plating: Gold-plated contacts enhance corrosion resistance and signal reliability.
- Insert: PA (nylon) insert provides electrical insulation and structural support.
- Housing: Zinc alloy housing offers strength and impact resistance.
- Flame-Retardant Rating: UL 94 HB rated materials for baseline fire safety.
- Protection Class: IP40 rated, protecting against solid objects larger than 1 mm.
- Operating Temperature Range: Functions reliably from -30°C to +80°C, suitable for varied environments.
Packaging and Accessories
- Individual Packaging: Each unit is packed 1 piece per bag for protection and cleanliness.
- Carton Packing: 50 pieces per inner carton, with 5 inner cartons per master carton (250 pieces per master carton).
- No Accessories Included: The MA3M3M ships as a standalone adapter with no additional screws, nuts, or fastener plates.
Product Dimensions
- Compact Length: Overall length of 76.00 ± 0.50 mm for easy integration into cable runs.
- Dual Diameter Profile: Body diameter of ø18.90 ± 0.20 mm, with a wider section of ø20.12 ± 0.20 mm for secure gripping and connector shielding.
Usage Notes
- Simple Inline Connection: The adapter requires no assembly — simply align and mate the male XLR connector on each end with the corresponding female XLR connectors of the cables or devices being connected.
- No Tools Required: Designed for tool-free, hand-tight connection and disconnection, consistent with its rated ≤20 N insertion/withdrawal force.
- Signal Direction Independent: As a male-to-male 3-pin adapter, it can be used to join two female-terminated cables or extend a signal chain where needed.
