Fischer MiniMax connectors

Fischer Connectors has expanded its flagship product line, the Fischer MiniMax Series, with three connectors and associated cables now featuring new options in pin layout, body size and data speed. The new additions include:

New pin-layout configuration: 7 contacts (4x signal, 3x power) in Ø 10 mm receptacle (Fischer Connectors reference ‘size 06’) with a configuration offering up to 22 AWG and a choice of three locking mechanisms (quick-release, push-pull, screw), as an alternative for designing even smaller equipment for the Nett Warrior connectivity ecosystem and for other rugged applications

New body size: Ø 14.0 mm (size 10) with 12 signal and power contacts offering USB 3.2 Gen 2 (10 Gbit/s, 1m) and high power up to 8A, suited for high-speed intercom boxes and next-generation hubs

New ultra-high density: 30 contacts (24x signal, 6x power) in Ø 14.0 mm (size 10), supporting multi-protocol data transmission (such as HDMI, USB, Ethernet) and extending the popular high-density layout offering for instrumentation applications, unmanned systems, and sensor and IoT interconnections.

The increased density and optimized packaging factor offered by the MiniMax series apply to a varied array of lightweight and compact solutions, from various connector configurations, through cable assemblies with straight, right-angle or 60° overmolding, to electronic solutions including hubs, flash drives and flex PCB circuits tailored to the size, weight and power (SWaP) requirements of entire electronic systems and ecosystems. This provides OEM engineers with more flexibility in terms of design when it comes to choosing from different connectivity solutions in line with specific system-level and field-application engineering requirements, harsh operating environments, as well as cost-efficiency criteria.

Smaller connectivity yields big advantages in terms of design integration. For example, the 12 mm diameter receptacle (size 08) with up to 24 power and signal contacts represents up to a 45% space saving compared to standard receptacles with a similar number of contacts. The external dimensions of electronic devices are affected by the growing demand for sensors and mobile (or wearable) electronics as well as for autonomous robotics and vehicles. This implies ever-lighter components. With up to 75% weight saving, the Fischer MiniMax Series achieves both size and weight reduction, maximizing performances while minimizing the integration burden.

When ruggedized for durable life cycles, lightweight and ultra-miniature solutions further increase flexibility and facilitate design integration for demanding applications. The main reliability features of the Fischer MiniMax Series are 5,000 mating cycles, 360° EMC shielding, IP68 sealing -20m/24h, gas tightness to 10-6 mbar l/s, high corrosion resistance, operating temperatures from -40 °C to +135 °C, blind mating, three secure locking mechanisms (quick-release, push-pull, screw), and cable assemblies with straight or angled bend relief overmolding.

YellowScan, a designer of lightweight UAV-lidar mapping solutions for surveying operations, has selected Fischer MiniMax connectors for use in its products due to a variety of factors: space and weight, rugged material, vibration resistance, dust and rain proofing with high IP sealing, large pin count and EMI shielding. YellowScan’s Mapper uses three Fischer Minimax connectors: 4 pins for the external power port; 24 pins (RJ45 and Universal Asynchronous Receiver Transmitter, UART) for the LiveStation port; and 19 pins (USB and General Purpose Input/Output, GPIO) for the optional camera port.

Jonathan Brossard, CEO of Fischer Connectors, commented: “Special know-how, skillsets and miniaturization and ruggedization processes and techniques are required from our R&D and Operations teams to design and manufacture our ultra-miniature, high-density and high-speed connectivity solutions. We are very proud we can provide the design engineering community with some of the smallest and densest connectivity solutions in the world, combined with unparalleled ergonomics and robustness.”

Jérôme Dabonneville, CTO of Fischer Connectors, noted: “The multiplication of sensors – reflecting a growing need for data acquisition and transmission – as well as the constant scale reduction of electronic components are the two main innovation drivers for ever-smaller, lighter and more capable high-density, ultra-miniature connectors, cable assemblies and electronic solutions. Demands for connectivity tailored to electronic devices and systems ensuring signal integrity and maximizing power & data functionality, performance and reliability, while containing or maintaining footprint to a minimum, are on the rise. The new solutions we are now making available to the market completes our Fischer MiniMax range in this direction. Tested to IEC, EIA and MIL-SPEC quality and reliability standards, they allow design engineers to accelerate innovative designs for various challenging applications in defense & security, UAVs and industrial instrumentation, to name just a few of the harsh operating environments for which our ultra-miniature connectivity solutions are particularly well suited.”
