Discover the ZMDC-25S Micro Connector: Small Size, Big Performance

The ZMDC-25S micro rectangular electrical connector is a compact powerhouse designed to meet the demands of modern connectivity. Its sleek dimensions—5.65mm shorter in length and 1.24mm narrower than the ZMDM series—make it an ideal choice for space-constrained applications. But don’t let its size fool you; this connector packs a punch. With a contact spacing of 1.91mm and row spacing of 1.65mm, it ensures reliable connections even in tight spaces. Whether you’re dealing with extreme temperatures (ranging from -55°C to +125°C) or challenging environments, the ZMDC-25S delivers. Its impressive insulation resistance of 5000 mΩ, mechanical life of 500 cycles, and shock resistance (490m/s²) make it a go-to solution for engineers seeking reliability and performance.
When precision matters, the ZMDC-25S steps up. Its low contact resistance (8 mΩ) ensures efficient signal transmission, while the 800V pressure resistance provides peace of mind in critical applications. Whether you’re designing medical devices, industrial machinery, or automotive systems, this connector has you covered. Its vibration resistance (10-2000Hz, 196m/s²) further enhances its durability. Imagine a connector that combines compactness, robustness, and versatility—all in one package. That’s the ZMDC-25S. Get connected today and experience the power of small yet mighty engineering.

Key Features of the ZMDC-25S Connector

Frequency Range: The ZMDC-25S operates across a wide frequency spectrum, spanning from 0.2 MHz to 250 MHz. This versatility makes it suitable for various applications, including HF/VHF communication systems and instrumentation.
Mainline Loss (Insertion Loss): When signals pass through the ZMDC-25S, the mainline loss (insertion loss) is typically a mere 0.35 dB. This low loss ensures efficient signal transmission, critical for maintaining data integrity in high-frequency environments.
In-Out Coupling: The coupling between the input and output ports is carefully engineered. At 0.2 MHz, the coupling factor is approximately 19.44 dB, gradually increasing to 19.58 dB at 250 MHz. This precise coupling minimizes signal leakage and optimizes performance.
Directivity: Directivity matters in connectors, especially when precision is paramount. The ZMDC-25S boasts excellent directivity, typically around 33 dB. This means that it efficiently directs signals from one port to another, reducing unwanted reflections and ensuring reliable data transfer.
Input Power Handling: With a robust design, the ZMDC-25S can handle up to 4 watts of input power. Whether you’re dealing with demanding industrial applications or sensitive radio equipment, this connector won’t back down.
Temperature Resilience: Operating temperature extremes won’t faze the ZMDC-25S. From icy -55°C to scorching +125°C, it maintains its performance. Engineers can rely on this connector even in harsh environments.
Connector Type: The ZMDC-25S features SMA connectors—a popular choice due to their durability and ease of use. These connectors ensure secure connections, making installation hassle-free.
