２．Crimping procedure
（１） Stripping the cable
The stripping specification and the cable cut dimensions after crimping are shown below.
Cable cut dimensions (GT21B-2426/1.6-2.9SCF + S type housing)
GT21T-1S-HU (GT21-1S-HU(*))
Cable cut dimensions (GT21B-2426/1.6-2.9PCF + P type housing)
GT21N-1PP-HU(*)
Note) The dimensions of the stripping specification are recommended values. In order to satisfy
the quality of crimping, please verify the crimp quality standard.

（２）Crimping
①Use our company’s applicator for crimping
②Inspection before cimping
・Before crimping, verify if any foreign matter is on the crimper and the anvil. If so, clear
it away.
・When setting up the terminal, verify there is no interference between the terminal and
the terminal plate (Picture1). (In case of interference, the terminal cannot be set up
correctly.)
・Verify the crimping data of the appropriate cable and, measure the C/H as shown on the
cross-section below.
When crimping, set the stripped coaxial cable by making the contact with the wire barrel and the
dielectric of the cable, as shown in the Picture1.

Appearance after crimping
The appearance after crimping is shown in Picture2. The dielectric of the cable may be deformed
but it doesn’t affect the product’s function.

The shield braid may be trapped between the edges of the shield barrel but it does not affect the
quality of the product unless it exceeds the area of the shield barrel.

（４）Recommended inspection
①Appearance
Should be free from flaws, deformations, plating separation etc.
②Withstand voltage
Should be free from short circuit or insulation breakage when 600V AC is applied for one
second.
2mA leak current should be regarded as insulation breakage.
③Conduction
The inner conductor and outer conductor should be conductive.
４．Instructions
（１）Do not touch the terminal contacts or inside of the barrel.
（２）Do not put any object on a terminal. Do not drop terminals. Otherwise, terminals may be
deformed or become dirty. Handle terminals carefully.
（３）Do not pull terminals forcedly when they are entangled. Disentangle carefully to avoid
deforming them.
（４）Be careful not to deform terminals when touching them.
（５）Do not store terminals in a dusty place.
（６）Do not apply intense shocks to terminals.
（７）Do not put wire harnesses on the floor.
（８）Connectors are easily affected by shocks. Do not throw or swing them.
（９）Do not handle parts in such a manner as the connector is deformed or flawed or terminals
are deformed.
