Discover the HUADA ZMDM-31PWP1 Connector: Compact Design, Robust Performance

The HUADA ZMDM-31PWP1 connector redefines compactness. With dimensions 2.78mm shorter in length, 5.4mm narrower, and 3.9mm lower than its predecessor (the J29A series), it’s a space-saving marvel. Whether you’re designing handheld devices, wearables, or IoT gadgets, this connector ensures efficient use of board real estate. Its volume reduction by approximately 40% compared to J29A opens up new possibilities for miniaturized electronics. Plus, the 1.91mm contact spacing and 1.65mm row spacing make it ideal for densely packed PCBs.
Beyond its size, the ZMDM-31PWP1 shines in reliability. It meets the GJB2446A standard, making it a trusted choice for rugged applications. The crimping cross-sectional area accommodates wire sizes from 0.15mm² to 0.35mm², ensuring secure connections. Operating between -55°C and +125°C, it withstands extreme temperatures. With low contact resistance (8 mΩ), mechanical durability (500 cycles), and pressure resistance (800V), this connector is your go-to solution for critical systems. Whether you’re in aerospace, automotive, or industrial electronics, the HUADA ZMDM-31PWP1 delivers performance without compromise.
