Summary

Fischer Connectors is a Swiss, family-owned circular connector manufacturer, now operating as the connector business unit of the Conextivity Group. Its MiniMax and UltiMate series are widely used in UAVs and robotics for hybrid power+data connectivity in ultra-miniature, sealed shells, including on drones such as Hexadrone’s Tundra and YellowScan’s LiDAR mapping payloads.

Key Facts

  • Founded: 1954 (Walter Werner Fischer, inventor of the world’s first hermetic connector)
  • Type: Component/subsystem supplier — connector manufacturer
  • Status: Active; family-owned through three generations; part of Conextivity Group (formed alongside sister company Wearin')
  • Key metric(s): ~600–700 employees group-wide; four R&D centers, six manufacturing sites including a Portugal plant operational by end of 2023; MiniMax series up to 24 signal/power contacts in a ø12mm receptacle (up to 45% space savings, 75% weight savings vs. standard receptacles per company claims); IP68 sealing over up to 5,000 mating cycles
  • Value chain position: Component/subsystem supplier (circular connectors, cable assemblies, and data/power hub electronics for UAV, robotics, defense, and medical OEMs)

What It Is / How It Works

Fischer Connectors’ core product is the circular connector (as opposed to Micro-D’s rectangular form factor), organized into several series by requirement: Fischer Core (general-purpose), UltiMate (high shock/vibration resistance), MiniMax (ultra-miniature, up to 30 signal and power contacts in a ø14mm shell per the company’s UAV materials), and FiberOptic (single/dual/quad optical channel, including hybrid optical+electrical variants). The company also sells “data and power hubs” (the Keystone series) that aggregate multiple sensor/power feeds into a single ruggedized connector interface, and rugged flash drives for transporting sensitive data in high-vibration environments.

For UAVs specifically, Fischer markets operating temperature ranges from -55°C to +135°C, high shock/vibration resistance, 360° EMC/EMI shielding, up to 1,000 hours of salt-mist corrosion resistance, and IP68/69 dust/water sealing — the same harsh-environment requirements as mil-spec Micro-D connectors, delivered in a circular hybrid-contact form factor rather than a rectangular one. Documented UAV customers include Hexadrone SAS (French UAV manufacturer, uses Fischer UltiMate USB 2.0 and MiniMax connectors on its modular Tundra drone) and YellowScan (LiDAR payload maker, uses three MiniMax connectors on its “Mapper” LiDAR unit for external power, LiveStation RJ45/UART data, and an optional USB/GPIO camera port).

Fischer Connectors is one of two business units under the Conextivity Group, alongside Wearin’ (an IoT wearables startup co-founded by third-generation family members Sabrina and Jonathan Brossard). The group has reported steady double-digit annual growth, doubling order intake over seven years and R&D staff over five years as of a 2023 leadership transition announcement.

Notable Developments

  • 2023-06-01: Generational leadership transition: Sabrina Brossard becomes President of the Board of Directors of Conextivity Group, succeeding her father Peter Fischer (President since 1999); Jonathan Brossard has served as CEO since 2016. The transition occurred a few months before the family group’s 70th anniversary.
  • 2023 (by end of year): New Fischer Connectors manufacturing plant in Portugal becomes operational.
  • 2023-11: Fischer releases new high-speed connectors and cable assemblies for UHD audio/video data transfer at 18 Gbit/s.
