Fischer Circular Connectors - Versatile solutions to meet your requirements
Posted on 20 May 2025
More than 70 years of world-renowned expertise, know-how and pioneering innovation in harsh-environment connectivity technologies such as ruggedness and endurance, sealing and hermeticity, miniaturization and high density, and faultless data transmission.
Wide range of shell sizes, keying options and pin configurations.
All our series feature rugged connectors
Heavy-use or safety-critical applications must be designed to withstand specific levels of mechanical stress and environmental conditions without degrading power, signal, or data transmission.
To endure the toughest conditions, our circular connectors, cables and electronic solutions are built and assembled with robust materials and a rugged design:
- Mechanical endurance to resist abrasion, wear, and intensive use – up to 10,000 mating cycles without any loss of signal or power
- Design and assembly robustness – resistance to vibration and shock, safe and extremely robust locking (push-pull, breakaway, screw) and keying (with easy error-proof blind mating as well as color-coding identification), mating-rotation resistance, ultra-resistant resin sealing (body and contact block), cable tensile strength up to 400 N (central strength member)
- Material mix (housing, plating, insulating, sealing, overmolding, jacketing) for increased hardness, flex endurance and resistance to environmental conditions such as high temperatures, radiation, corrosion and salt fog, chemicals (sterilization, disinfection and decontamination proof)
- 360° shielding ensuring EMI/RFI protection for faultless data transmission (data integrity and security).
‘Ruggedization’ methods and processes pertain to the entire designing, engineering and manufacturing chain of our circular connectors, cable assembly and electronic solutions – from choosing high-quality materials for housing, coating, plating, insulating and sealing, to overmolding or jacketing cables to protect the insulation and conductor core against environmental aggression and chemical deterioration, etc.
