MiniMax™ Connectors

Introduction

Fischer Connectors’ MiniMax™ series is a family of high-density miniature circular connectors intended for applications where size, weight, and power constraints are important. The series combines signal and power contacts with support for high-speed interfaces including USB 3.2 Gen 2, Ethernet, and audio/UHD video.

The technically notable aspect of the MiniMax™ range is its effort to bring multiple connection functions into a compact circular format while retaining environmental sealing, electromagnetic compatibility measures, and locking options suited to demanding equipment integration.

What it does

MiniMax™ connectors provide interconnection for power, signals, and supported high-speed data links in a miniature circular connector system. Depending on the connector configuration, the series can support USB 3.2 Gen 2, Ethernet, and audio/UHD video connectivity.

The connectors are designed with high-density miniaturization and offer wire support up to 18 AWG, with current ratings up to 10 A. Their housings provide IP68 sealing to 20 m for 24 hours, while the stated operating-temperature range is -40°C to +135°C.

For mechanical connection, the series is available with push-pull, screw, or quick-release locking systems. Blind-mating capability can simplify connections where the mating interface is not directly visible or easily accessible. The design also includes 360° EMC shielding and corrosion resistance.

Applications

Potential uses that follow from the MiniMax™ connector capabilities include:

• Compact equipment requiring combined power and signal interconnections
• Systems using USB 3.2 Gen 2 or Ethernet links in space-constrained enclosures
• Audio or UHD-video equipment requiring a rugged circular connection format
• Equipment exposed to wet or harsh environments where IP68 sealing is required
• Installations where blind mating or a push-pull, screw, or quick-release coupling mechanism is useful
• High-density cable assemblies using conductors up to 18 AWG

Design considerations

Connector selection should account for the required interface type, conductor size, and current requirement. The stated 10 A maximum current rating and support for wire sizes up to 18 AWG should be evaluated against the needs of the intended power circuit.

The chosen locking system—push-pull, screw, or quick-release—will affect retention, connection workflow, and mechanical integration. Blind-mating capability may be relevant for enclosed equipment or locations with limited access.

For installations exposed to moisture, the IP68 specification is stated as sealing to 20 m for 24 hours. The operating range of -40°C to +135°C, corrosion resistance, and 360° EMC shielding are also relevant considerations for environmental and electromagnetic design requirements. The series lists 5,000 mating cycles and references testing to IEC, EIA, MIL-STD-202, and MIL-STD-810 standards.
