 Product information
minibend™
minibend is a truly flexible coaxial cable assembly which is designed for use in low profile, internal, point-to-point interconnections
between RF modules within communications systems. minibend replaces .086 inch custom semi-rigid cables with standard flexible
cables, eliminating the need for predefined custom lengths and bend configurations. minibend provides you with a preassembled
and tested high performance, cost-effective alternative in a variety of standard lengths and connector configurations.

minibend R is designed for use in complex, congested environments where higher cable retention force is required. minibend R's
pull strength is more than 70 % greater than a standard minibend. When installed and bent at the minimum bend radius, minibend R
will tolerate multiple 90° rotations at the cable/connector junction. The «R» ruggedisation can be added to any minibend connec-
tor style. All materials used in minibend R assemblies meet or exceed NASA TML and CVCM requirements for use in spacecraft
applications.

Features and benefits

 microbend™
microbend assemblies provide you with a standard preassembled and tested high performance, cost-
effective truly flexible alternative to .047 inch custom semi-rigid cable assemblies, eliminating the need for
predefined custom lengths and bend configurations. microbend features include 35 % lower loss than
.047 inch semi-rigid cable, a minimum bend radius of 1.52 mm (0.060 inch) and triple shielding for high
isolation. microbend assemblies are available with a wide range of connector interfaces. All microbend
assemblies are available only in a ruggedised version.
microbend is designed for use in complex, congested environments where higher cable retention force is
required. When installed and bent at the minimum bend radius, microbend will tolerate multiple 90°
rotations at the cable/connector junction. All materials used in microbend assemblies meet or exceed
NASA TML and CVCM requirements for use in spacecraft applications and are available only in a
ruggedised version.
minibend assemblies are available in lengths from 63.5 mm (2.50 inch) to 304.8 mm (12.00 inch). The
respective item numbers are listed on page 35–37 of this product catalogue.
For connector combinations other than those mentioned in the following pages, see the standard assem-
bly selection matrix on page 6/7 of this product catalogue.

How many times can I bend the cable?

radii and smaller bend angles will allow more bend cycles.

What do you mean by a «truly flexible» cable?

path between the two connectors.

HUBER+SUHNER Astrolab's minibend connectors were desi-

gned to replace the traditional right angle box and sweep
connectors with a lower profile straight connector to allow for
point-to-point installations in systems where there is minimal free
space. This technology utilises the cable to perform the 90°
bend behind the connector. For any system where the minibend
is replacing right angle connectors, the length of the assembly
must be increased to include the additional cable length re-
quired to make the bend behind the connector.

The figures below show how long the minibend cable assem-
bly must be from reference plane to reference plane if it is to
replace a traditional right angle connector assembly.
