Fischer Connectors: safe, reliable, rugged solutions for harsh defence environments


About Fischer Connectors


Known for their reliability, precision and resistance to demanding and harsh environments, Fischer Connectors’ connectivity solutions – both electrical and optical connectors, cable assemblies and active devices – are ideally suited for use in defence operations globally.

Tested to MIL-SPEC and IEC standards, Fischer Connectors’ products are engineered to withstand the most extreme field conditions in Dismounted Soldier, Ground, Aerospace and Marine applications. They are ideally suited for military devices, equipment and electronic ecosystems in terms of SWaP requirements (Size, Weight and Power), cable management optimisation and integrated wearable technology for the Dismounted Soldier Modernisation Programme and in line with the Generic Soldier Architecture (GSA).

  • Human factor engineered
  • Rugged, lightweight and compact
  • Easy blind mating, even with gloves
  • Sealed (up to IP68, even unmated) and hermetic connectors
  • Extreme temperature resistance, dust- and sand-proof solutions
  • EMI shielded connectors for reliable data transmission
  • Designed for durability and stealth

  • Configurations of 4 to 24 contacts, sizes 06 and 08 with receptacles of 10mm and 12mm footprint respectively
  • Tough: IP68 (2m/24h) sealing (both mated and unmated), unbreakable keying system withstanding more than 4 Nm of torque, over-molded assemblies withstanding 40kg of pull (break-away) force


Fischer FreedomTM Series: easy mating, easy cleaning, easy integration


Fischer FreedomTM Series: easy mating, easy cleaning, easy integration

The multiple award-winning breakthrough plug & use Fischer Freedom™ Series serves as a versatile technology platform and innovation enabler in connectivity and application design, setting new standards in usability, integration capability and versatility for any defence applications.

  • Low-profile Fischer LP360TM connectors (in metal and high-end & durable plastic), cable assemblies and active devices (LED, USB adaptor, rugged flash drive)
  • 360° blind mating freedom (no key code) with non-magnetic quick-release locking mechanism
  • 4 or 7 signal and power contacts, up to 24AWG, USB 2.0 and Ethernet
  • Fully cleanable (plug and receptacle) thanks to membrane-sealed contacts
  • IP68 sealed to -20m/24h (metal version) IP67 sealed mated and unmated (plastic)
  • Optimized cable management: reduced clutter and snagging thanks to 360o mating freedom and any direction cable plugging and routing, possible cable-free solutions with the direct integration of the plug into the device’s housing.
