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

The ZMDC-31SS micro rectangular electrical connector is a compact powerhouse designed for efficiency and reliability. Its diminutive size—5.65mm shorter in length and 1.24mm narrower than the ZMDM series—makes it an ideal choice for applications where space is at a premium. Whether you’re working on intricate electronics or tight enclosures, the ZMDC-31SS delivers exceptional performance.
Inside this tiny connector lies a host of impressive features. With contact spacing at 1.91mm and row spacing at 1.65mm, it ensures secure connections without sacrificing space. The conductor’s cross-sectional area ranges from 0.15mm² to 0.35mm², accommodating various wire sizes. Plus, its robust construction withstands temperatures from -55°C to +125°C, making it suitable for diverse environments. Whether you’re building precision instruments or industrial machinery, the ZMDC-31SS is your reliable partner.

Key Features of the ZMDC-31SS Connector

Frequency Range: The ZMDC-31SS covers an impressive frequency range, spanning from a low 0.1 MHz to a robust 250 MHz. Whether you’re dealing with high-frequency applications or need reliable performance in the VHF spectrum, this connector has you covered.
Coupling (dB): Nominal coupling stands at 30 dB ± 0.5 dB. That’s the sweet spot for efficient signal transfer without excessive loss.
Flatness is maintained within ±0.5 dB, ensuring consistent performance across the entire frequency band.
Mainline Loss (dB): Typical mainline loss is a mere 0.4 dB, making it an excellent choice for critical connections.
Even at its maximum, the loss remains impressively low at 0.6 dB.
Directivity (dB): Directivity matters, especially in precision applications. The ZMDC-31SS boasts a typical directivity of 23 dB, with a minimum of 18 dB. This ensures minimal interference and maximum signal integrity.
VSWR (Voltage Standing Wave Ratio): The VSWR, a measure of how well the connector handles reflected signals, maintains a typical value of 1.5:1. Low VSWR means efficient power transfer and reduced signal reflections.
Maximum Power Input: Up to 3 watts (W) can flow through this connector. Robust power handling ensures reliability even under demanding conditions.
Operating Temperature Range: From chilly -55°C to scorching +125°C, the ZMDC-31SS remains unfazed. It’s ready for extreme environments, whether you’re exploring the Arctic or working near industrial machinery.
Insulation Resistance: A solid 5000 mΩ of insulation resistance keeps unwanted leakage at bay.
Mechanical Life: Expect 500 cycles of reliable connection and disconnection. That’s durability you can count on.
Impact Resistance: Withstanding 490 m/s² of impact force, this connector laughs in the face of accidental bumps and jolts.
Vibration Resistance: The ZMDC-31SS dances to the tune of vibrations from 10 Hz to 2000 Hz, maintaining stability at 196 m/s². Shake it, and it’ll stay connected!
Contact Resistance: A mere 8 mΩ of contact resistance ensures efficient power transmission and minimal energy loss.
Relative Humidity: At 40°C and 98% humidity, this connector remains unfazed. Rain or shine, it’s got your back.
Pressure Resistance: Up to 800V of pressure won’t break its stride. Whether it’s high-voltage applications or just a tight fit, the ZMDC-31SS handles it with ease.
