Discover the ZMDC-31S1S Connector: Small Size, Big Impact

Compact Design, High Performance: The ZMDC-31S1S connector series combines small dimensions with impressive capabilities. Measuring 5.65mm shorter in length and 1.24mm narrower than its predecessor (the ZMDM series), this connector is ideal for space-constrained applications. Its contact spacing of 1.91mm ensures efficient connections, while the conductor area ranges from 0.15mm² to 0.35mm². With a temperature range of -55°C to +125°C, high insulation resistance (5000 mΩ), and low contact resistance (8 mΩ), the ZMDC-31S1S delivers reliable performance even in challenging environments.
Robust and Reliable: Built to withstand mechanical impact (490m/s²) and vibration (10-2000Hz, 196m/s²), the ZMDC-31S1S connector ensures durability. Its current rating of 5 A and pressure resistance up to 800V make it suitable for various industrial and electronic applications. Whether in automotive systems, consumer electronics, or industrial machinery, the ZMDC-31S1S micro connector offers a compact solution without compromising performance.

Key Features of the ZMDC-31S1S Connector

Frequency Range: The ZMDC-31S1S operates efficiently across a broad frequency spectrum, spanning from 0.1 MHz to 250 MHz. Whether you’re dealing with high-frequency signals or lower-frequency applications, this connector has you covered.
Coupling Performance: Nominal coupling is set at 30 dB, with an impressively tight tolerance of ±0.5 dB. This precise coupling ensures consistent signal transfer between ports.
The flatness of the coupling response remains remarkably stable across the entire frequency range. So, whether you’re dealing with narrowband or broadband signals, the ZMDC-31S1S maintains its performance.
Mainline Loss (Insertion Loss): When signals pass through the coupled port, the mainline loss (insertion loss) is typically a mere 0.5 dB. This low loss minimizes signal attenuation, making it an excellent choice for critical applications.
Exceptional Directivity: Directivity, which measures the isolation between the input and coupled ports, is a standout feature. The ZMDC-31S1S achieves approximately 23 dB of directivity, ensuring minimal signal leakage and cross-talk.
Return Loss for Signal Integrity: At the input port, the return loss is optimized. This means that unwanted signal reflections are effectively suppressed, maintaining signal integrity and reducing interference.
Temperature Resilience: Operating temperature ranges from -55°C (chilly environments) to 100°C (warmer conditions). Whether it’s a frigid outdoor setup or a heated industrial environment, the ZMDC-31S1S remains reliable.
Mechanical Specifications: The ZMDC-31S1S features SMA coaxial connections, a popular choice for RF applications.
