High data transmission speeds in ever-smaller footprints

Fischer Connectors Group’s ultra-miniature, rugged series of connectors, cable assemblies and electronic solutions has been extended to help engineers add more functionality and meet high-speed data acquisition and transmission requirements in applications with extreme limitations in space, even in harsh operating environments.

The flagship product line Fischer MiniMax Series, which already includes one of the smallest and densest connectors in the world, now includes three connectors and their associated cables with new options in pin layout, body size and data speed.

The increased density and optimised 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, maximising performances while minimising the integration burden.

The Fischer MiniMax connector in size 06 includes up to 12 power and signal contacts in a footprint of just 10 mm. This represents a density factor of 0.83, a unique technological feature for a connector with standard 0.5 mm contacts. The density factor is equal to the receptacle diameter divided by the number of contacts available in that receptacle size.

When ruggedised for durable life cycles, lightweight and ultra-miniature solutions further increase flexibility and facilitates design integration for demanding applications. The main reliability features of the Fischer MiniMax Series are 5,000 mating cycles, 360° EMC shielding, IP68 sealing, 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.
