Metal fitting for clamping
Note 1 : When ordering the SR30-10PE-6P or SR30-10PX-6P, order SR30-P cable clamps separately, because such
plugs have no cable clamps.
Note 2 : The inner diameter of solder pot for male contact is Ø0.8.
Note 3 : Cable clamping force, cable rotation force, and other aspects may differ depending on the cable construction.
We recommend that you verify the suitability of the cable assembly before use or production.

.
2. Pass the cable through the hood and
metal fitting for tightening in order. Cut
the cable end at an approximate length
as shown in the figure on the left.
3. Insert the block into the jig for termination
and terminate the cable by soldering.
4. Crimp the cable onto the metal fitting for
clamping (SR30-P) several times with
using the crimping tool (SR30-10PE-T),
in such a way that the outer diameter
becomes approximately Ø5.2.
5. After termination, tighten the metal
fitting for tightening into the threaded
section on the block (P shell, J shell) to
a torque of approximately 2 N•m (20
kg•cm), using a single-acting torque
wrench. When performing tightening on
the jack side, be sure to fix the wrench
application point on the J shell.
6. Secure the metal fitting for clamping by
tightening a set screw on either side of
the two bosses on the metal fitting for
clamping to a torque of approximately
0.1 N•m (1 kg•cm) in such a way that the
tip of the set screw slightly sinks.
7. Place the hood over the metal fitting for
tightening. The procedure has been
completed. Please be sure to apply a
small amount of thread adhesive to
prevent loosening.
