Product Outline Drawing And Dimensions

Plug: SR30-10PE-6P(74)

Dimensional drawing (representative image)
(Note 1) When ordering the SR30-10PE-6P or SR30-10PX-6P, order SR30-P cable clamps separately, because such plugs do not include cable clamps.
(Note 2) The inner diameter of the solder pot for the male contacts is ø0.8 mm.
(Note 3) Cable clamping, cable rotation, and other forces may vary with the cable construction. Make sure that your cable is suitable for use with these connectors before usage and production.

Receptacle (nut-fastening method): SR30-10R-6S(71)

(Note 1) When ordering the SR30-10JE-6S, order SR30-P cable clamps separately, because such plugs do not include cable clamps.
(Note 2) The inner diameter of the solder pot for the female contacts is ø0.9 mm.
(Note 3) Cable clamping, cable rotation, and other forces may vary with the cable construction. Make sure that your cable is suitable for use with these connectors before usage and production.
Receptacle DIP Post Configuration Dimensions

- 1. The diagram shows the view from the mating surface side of the receptacle.
- 2. A machining tolerance of ±0.05 for DIP post configuration dimensions is recommended.
Reference Termination Procedure (Plug and Jack Side)

Reference Termination Procedure (Plug and Jack Side)
1. Please use the cables with a finished outer diameter of between ø4.2 and 4.8 mm and a nominal conductor cross-section of 0.3 mm2.
2. Pass the cable through the hood and metal fitting for tightening in that order. Cut the cable end at an approximate length as shown in the diagram.
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 using the crimping tool (SR30-10PE-T), in such a way that the outer diameter becomes approximately ø5.2 mm.
5. After termination, tighten the metal fitting for tightening onto 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 2 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 to complete the procedure.
(Be sure to apply a small amount of thread adhesive or similar to prevent loosening.)
