The SpaceSplice
™
Wire Connecting Solution is a series of high-
reliability connectors developed specifically for aerospace applications
like satellites, payloads, harnesses, thermistors, and multilayer
insulators, where space and weight saving can be a critical factor.
SpaceSplice one-way series use two wires as the standard solution.
The four-way series is a stackable wire-to-wire connector with
removable contacts, which can be beneficial in space applications
where more than four ways are needed.
Benefits
▪ Reduces cable installation time
and reduces total system cost
▪ Increases reliability by utilizing
standard crimping processes
▪ Compact format & designed
for commonly used wire diameters
▪ Low residual magnetism & no outgassing

▪ ESA/ESCC 3401/097 certified product
▪ High radiation and temperature resistance: PEEK material
▪ Using D*MA crimpable contacts technology
Markets/Applications
▪ Space equipment
▪ Satellites harnesses and payloads
▪ Launchers
▪ Military / Avionics

Problem/Solution
MDMA and MDMB are high-performance micro-miniature connectors
with removable crimp contacts for easy installation and rework. The
MDMA meets ESA qualifications for space applications, and MDMB is
for Space Engineering Models, avionics, military, medical, and industrial
applications. Certified by the European Space Agency and compatible
with MIL-83513, they are ideal for harnesses in satellites and harsh
environments, including board-to-board, board-to-cable, and cable-to-
cable applications. Their unique design is compatible with standard
Micro-D connectors, providing custom harness solutions.
Benefits
▪ Small form-factor connectors & low weight
▪ Flexibility to easily create custom cable
harness with application-specific lengths
▪ No soldering or heat-shrink tubing required
▪ Connectors not subject to outgassing
▪ Easy rework with removable crimp contacts
