Discover the ZMDC-21PNP Micro Connector: Small Size, Big Impact

The ZMDC-21PNP micro rectangular connector packs impressive performance into its diminutive form. Measuring 5.65mm shorter in length and 1.24mm narrower than its predecessor, the ZMDM series, this connector is a space-saving marvel. Its high pin density makes it ideal for applications in aerospace avionics, radar systems, and medical devices. Despite its small size, the ZMDC-21PNP boasts robust construction, with excellent shock and vibration resistance. Whether in extreme temperatures (ranging from -55°C to +125°C) or under pressure (up to 800V), this connector delivers reliable connectivity.
Let’s delve into the technical details. The ZMDC-21PNP features a contact spacing of 1.91mm and row spacing of 1.65mm. Its conductor cross-sectional area ranges from 0.15mm² to 0.35mm², ensuring efficient electrical conductivity. With low contact resistance (8 mΩ) and insulation resistance of 5000 mΩ, it meets demanding performance standards. This connector can handle a current of up to 5 A and withstands mechanical stress (500 cycles), impact (490m/s²), and vibration (10-2000Hz, 196m/s²). In summary, the ZMDC-21PNP combines compactness, durability, and technical prowess for a wide range of applications.

Key Features of the ZMDC-21PNP Connector
