Miniature connectors deliver more options for high-speed data transmission

Fischer Connectors Group has expanded its flagship MiniMax series of ultra-miniature, rugged connectors and cables with new options for pin layout, body size, and data speed. Comprised of three miniature connectors (sizes 06, 08, and 10) and their related cables, the new options enable the interconnect solutions to meet high-speed data transmission requirements in applications with space constraints and harsh environments.

The new pin-layout configuration offers seven contacts (4× signal, 3× power) in a 10-mm receptacle (size 06), supporting up to 22 AWG and three locking mechanisms (quick-release, push-pull, screw). The new 14.0-mm (size 10) body size with 12 signal and power contacts offers high power up to 8 A and supports USB 3.2 Gen 2 (10 Gbits/s, 1 m), making it suited for high-speed intercom boxes and hubs.

The series also offers ultra-high density with 30 contacts (24× signal, 6× power) in the 14.0-mm (size 10) body size. The higher density option supports multi-protocol data transmission such as HDMI, USB, Ethernet. It extends the high-density layout for instrumentation, unmanned systems, as well as sensor and IoT interconnection applications.

The Fischer MiniMax series claims one of the smallest and highest density connectors. The connector in size 06 includes up to 12 power and signal contacts in a 10-mm footprint, representing a density factor of 0.83, which is a unique feature for a connector with standard 0.5-mm contacts, said the company.

Key environmental features include 5,000 mating cycles, 360° EMC shielding, IP68 sealing (20 m/24 h), <10^-6 mbar l/second gas sealing, and an operating temperature range from -40°C to 135°C. The connectors also offer high corrosion resistance. Other features include blind mating, three secure locking mechanisms, and cable assemblies with straight or angled bend-relief overmolding.

The MiniMax connectors are tested to IEC, EIA, and MIL-STD quality and reliability standards. This makes them suited to a variety of harsh environment applications such as defense and security, UAVs, and industrial instrumentation.
