Discover the HUADA ZMDM-31PS Micro Connector: Compact, Reliable, and Versatile

The HUADA ZMDM-31PS micro rectangular electrical connector redefines compact connectivity. Imagine a connector that’s 2.78mm shorter, 5.4mm narrower, and 3.9mm lower than its predecessor—the J29A series. It’s like fitting a high-performance engine into a sleek sports car chassis. Whether you’re designing cutting-edge medical devices, aerospace avionics, or rugged military equipment, the ZMDM-31PS delivers. Its crimping cross-sectional area accommodates 0.15mm² to 0.35mm² wires, ensuring secure connections. Plus, it meets the stringent GJB2446A standard, so you can trust it in critical applications. Small in size, big on performance—that’s the ZMDM-31PS promise.
Beyond dimensions, this connector boasts resilience. It laughs in the face of extreme temperatures, from a chilly -55°C to a sizzling +125°C. Its mechanical life spans 500 cycles, surviving the rigors of repeated use. Even under pressure—4.4 KPa, to be precise—it stands firmAnd when it comes to contact resistance, it’s a mere 8 mΩ—ensuring efficient power transfer. So, whether you’re building life-saving medical equipment or pushing the boundaries of aerospace technology, the HUADA ZMDM-31PS connector is your compact powerhouse.
