Note. These connectors are of insert type. As the crimping type, the following connectors (Molex) are recommended.

For CNP1: 51241-0600 (connector), 56125-0118 (terminal)
For CNP2: 51240-0500 (connector), 56125-0118 (terminal)
For CNP3: 51241-0300 (connector), 56125-0118 (terminal)
Crimping tool: CNP57349-5300
<Connector applicable cable example>

Cable finish OD: to 3.8mm

(b) Termination of the cables

Solid wire: After the sheath has been stripped, the cable can be used as it is.

8 to 9mm

Sheath

Core

Twisted wire: Use the cable after stripping the sheath and twisting the core. At this time, take care to avoid

a short caused by the loose wires of the core and the adjacent pole. Do not solder the core as
it may cause a contact fault. Alternatively, a bar terminal may be used to put the wires
together.
