Its streamlined dimensions—5.65mm shorter in length and 1.24mm narrower than the ZMDM series—make it ideal for tight spaces without compromising performance. With a contact spacing of 1.91mm and row spacing of 1.65mm, this connector ensures efficient signal transmission. Whether in extreme temperatures (ranging from -55°C to +125°C) or under pressure (up to 800V), the ZMDC-31PP delivers reliability. Its 500-cycle mechanical life, low contact resistance (8 mΩ), and impressive insulation resistance (5000 mΩ) make it a standout choice for demanding applications.
The ZMDC-31PP connector boasts a compact footprint but packs a punch. Its impact resistance (490m/s²) and vibration tolerance (10-2000Hz, 196m/s²) ensure durability even in challenging environments. With a current rating of 5 A, it handles power efficiently. Whether you’re designing industrial machinery, automotive systems, or consumer electronics, the ZMDC-31PP micro connector combines smart engineering with space efficiency. Trust it to keep your circuits connected seamlessly while optimizing valuable real estate on your PCBs.

Key Features of the ZMDC-31PP Connector

Frequency Range: The ZMDC-31PP operates seamlessly 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 Factor: The coupling factor (also known as coupling loss) is a critical parameter. For the ZMDC-31PP, it falls within the range of approximately 30.66 dB to 31.09 dB. This factor determines how effectively the coupler transfers energy from the mainline to the coupled port.
Mainline Loss (Insertion Loss): When signals pass through the coupled port, there’s a slight loss due to the coupler’s design. The mainline loss for the ZMDC-31PP typically ranges from 0.24 dB to 0.35 dB. This minimal loss ensures efficient signal transmission.
Directivity: Directivity measures how well the coupler isolates the coupled and through ports. In the case of the ZMDC-31PP, directivity values fall between 28.18 dB and 40.64 dB. Higher directivity means better isolation, which is crucial for accurate measurements and signal integrity.
Power Handling Capability: The ZMDC-31PP can handle power inputs with aplomb. Its average power handling capacity ranges from 1 W to 3 W. Whether you’re dealing with low-power applications or more demanding scenarios, this connector won’t flinch.
Operating Temperature Range: From frigid environments to moderate heat, the ZMDC-31PP remains steadfast. It’s designed to operate within a temperature range of -55°C to 100°C. So whether you’re in an Arctic lab or a desert field, this connector keeps performing.
Connector Type: The ZMDC-31PP features SMA connectors. SMA connectors are widely used in RF and microwave applications due to their robust design and excellent performance characteristics.
