Quality Levels
ESA/ESCC Quality Level.
The Dole plant (France) is qualified by ESA for the supply of Microminiature connectors Type MTB1, according to the ESCC Generic
Specification N° 3401, and to the applicable ESCC Detail Specification n° 3401/031.
First qualification obtained in 1986 (renewed every 2 years).
Qualification certificate: 141 (MTB1).
Applications: Flight equipments, satellites, launchers (ESA requirements).
FR022 Quality Level.
“Commercial Space Grade”.
C&K Connector Specification CS FR022, amendment to the ESCC Generic Specification n° 3401, for low cost products manufactured:
- in the same ESA qualified site
- through the same manufacturing and control processes
- with the same piece parts
- with lighter controls, documentation and traceability
Applications: Engineering models, ground equipments, testing, some flight equipments (no need for high requirements).
The connectors and accessories, supplied according to these 2 quality levels, are totally compatible, interchangeable, and
intermateable, as they are manufactured with the same piece parts (except the cables), in the same ESA qualified site.
