Discover the ZMDC-31SL5 Micro Connector: Compact, Reliable, and Versatile

The ZMDC-31SL5 micro rectangular connector combines compact dimensions with impressive performance. 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 cross-sectional area ranges from 0.15mm² to 0.35mm². With a temperature range spanning from -55°C to +125°C, the ZMDC-31SL5 delivers reliability even in challenging environments.
Designed for durability, the ZMDC-31SL5 boasts a mechanical life of 500 cycles, impact resistance (490m/s²), and vibration tolerance (10-2000Hz, 196m/s²). Its low contact resistance (8 mΩ) ensures efficient signal transmission. Whether in industrial machinery, automotive systems, or consumer electronics, the ZMDC-31SL5 stands out as a reliable and space-saving connector solution.

Key Features of the ZMDC-31SL5 Connector

Frequency Range: The ZMDC-31SL5 operates efficiently across a frequency range spanning from 0.1 MHz to 250 MHz. Whether you’re dealing with high-frequency (HF) or very high-frequency (VHF) applications, this connector has you covered.
Coupling and Directionality: With a coupling value of 30 dB ±0.5 dB, the ZMDC-31SL5 ensures effective signal transfer. Additionally, its directivity—measuring the isolation between input and coupled ports—is a minimum of 23 dB. This robust directivity minimizes unwanted signal leakage.
Impedance Matching (VSWR): The Voltage Standing Wave Ratio (VSWR) is a critical factor for impedance matching. The ZMDC-31SL5 maintains a VSWR of 1.5:1 maximum, indicating excellent impedance alignment. This feature contributes to reliable signal transmission.
Mainline Loss and Efficiency: The mainline loss (insertion loss) is typically 0.5 dB. This low loss ensures minimal signal attenuation, making the ZMDC-31SL5 an efficient choice for your applications.
Power Handling Capacity: When it comes to power, the ZMDC-31SL5 can handle up to 3 watts of input power. This robust power handling capability ensures stability even under demanding conditions.
Temperature Range and Durability: Operating temperatures span from -55°C to +100°C. Whether you’re in extreme cold or heat, the ZMDC-31SL5 remains reliable. Its rugged construction ensures longevity and performance consistency.
Connector Type and Dimensions: The ZMDC-31SL5 features SMA connectors, known for their durability and versatility.
Dimensions: Length (A): Approximately 1.50 inches (38.10 mm)
