Rugged Interconnects for Harsh Environments eBook

Monitoring of electrical signals ensures that interconnect solutions can withstand shocks of high G amplitude, in compliance with MIL-STD-202 Method 213 and EIA-364-27. Drop resistance tests measure the mechanical deformation that could impact the connection’s functioning and performance following drops or bump shocks from different heights. The most rugged connectors designed by Fischer Connectors, the Fischer UltiMate Series, can withstand random vibration of up to 37.80 Grms and shocks of up to 300 G amplitude (half sine pulse of 3 ms, no discontinuity > 1 μs).

conditions it will experience throughout its service life and establishing chamber test methods that replicate the effects of environments on the equipment rather than imitating the environments themselves. Although prepared specifically for military applications, the standard is often used for commercial products as well. Standardized connectivity products that operate within the temperature range of -55°C to +135°C are available. Cabled connectors overmolded with TPU material withstand temperatures ranging from -40°C to +125°C, whereas soft caps resist a temperature of +85°C. Tailored solutions can be designed to reach much higher or lower temperatures for dedicated applications. For example, IP68/69 sealed and hermetic chromium-plated brass connectors can resist chemicals and extreme temperatures ranging from -100°C to +200°C. The premium materials used in such connectors also allow them to withstand most sterilization methods used in medical applications, such as steam autoclaving per IEC 60601-1.

High-end solutions may be tested for compliance with the U.S. Military Standard 810, Methods 501.6 (high temperature) and 502.6 (low temperature). This standard emphasizes tailoring an equipment’s environmental design and test limits to the Data transmission must remain stable even when there are vibrations. ME-Meßsysteme’s six independent strain gauge sensors rely on the ultra-miniature, vibration- resistant Fischer MiniMax Series. EXTREME TEMPERATURE RESISTANCE

Sterile or aseptic connectors and cable assemblies must be appropriately sealed to withstand ingress from steam saturated with water under at least 15 psi of pressure during multiple autoclave sterilization cycles (up to 1,000 cycles) that usually last 30 minutes. The World Health Organization recommends that hospital instruments and all equipment in the hospital rooms should be saturated in an autoclave at 121°C (250°F) for 30 minutes or 134°C (273°F) for 13 minutes. Fischer Core Series Brass, Stainless Steel, and Plastic 405 connectors are sterilizable in autoclave, Cidex, EtO, gamma radiation, Steris, or Sterrad systems.
