• Automotive / Medical / Industrial applications
Specification
• High performance Micro-miniature connectors meet
stringent tests for outgassing and residual magnetism and
are suitable for use in Space Engineering Model, Avionics,
Military, Medical and Industrial applications.
• Suitable for Board to Board, Board to Cable or Cable to
Cable applications.
• Twist Pin Contacts Technology.
• Sizes available: 9, 15, 21, 25, 31, 37 and 51 ways.
• Accepted wires size: Insulated wire AWG26 and AWG28.
• Distance between 2 adjacent contacts: 1.27mm (.050 inch).
• Distance between 2 contacts rows: 1.09mm (.043 inch).
Quality Level
• “Commercial Space Grade”).
• C&K Connector Specication CS FR022, for low cost products
manufactured:
- in the same ESA qualied site
- Through the same piece parts
- With lighter controls, documentation and traceability.
• The connectors are totally compatible, interchangeable
and intermateable with ESA quality level connectors ESCC
3401/029 (MDM connectors), 3401/41 (connector Savers),
3401/032 (accessories), 3401/077 (MDMA connectors),
3401/078 (contacts) and 3401/087 (backshells).
Process to use it
• Wire stripping.
• Cables soldering onto contacts.
• Wires cable installed by the end user.
Options
• Optional captive nuts or oat mounting.
Packaging
• Individual packaging.
• Each Micro-D connector is sold and delivered with a dust cap
in individual plastic bag.
• Each socket Micro-D connector is sold and delivered with
interfacial seal.
