NCS Panel Mountable Receptacle (Screw)

Caution
Product Description
[Features]This is a screw-type panel-mount receptacle manufactured by Nanaboshi Electric Mfg. A metal connector with a wide variety of shell sizes. This connector is mounted on the panel and used to connect to the cable side.

● A connector that is used for mounting onto panels and connecting to the cable side.

·The mating counterparts follow. For combination, be sure to combine the male (pin) and female (socket) components.
Straight Plugs
Conduit Plugs
Angle Plugs
·To protect the insulator of products of 80A or more from the heat of the solder, the contact can be removed from the insulator.
·The flange for shell size 50 to 64 is a square model.
· Does not support key position changes.

General-purpose Large Metal Connector (NCS)
Features
● NCS series connectors are round metal connectors that have been used conventionally as general-purpose type connectors.● The structure is simple, robust, mechanically and electrically stable; some items have acquired the mark (Electrical Appliance and Material Safety Act compliant), so they can be used widely from power supply to signal transmission.
● There are 10 shell sizes, each of which offers a selection among panel mounting, cable mounting, and relay mounting, providing a wide variety of combinations to suit the application.
● Because these connectors are all connected by soldering, no dedicated tool is required for wiring.
● The structure is an original design and cannot be coupled with other companies' products.

NCS Connector Contact Arrangement Diagram


Connection Work Method
Note: If a contact for 80 A or 150 A is mounted, use the following procedure.
(1) Loosen the lock screws and remove the insulator from the connector body (turn counterclockwise)
(2) Loosen the clamp screws and remove the clamp saddle from the connector body
(1) Insert the contact wrench from the coupling side and remove the contact locking nut
Note: Avoid mistakes in the order or direction of parts.
(1) Insert the core wire with extra solder into the contact solder pot(2) Heat the contact and the core wire with a soldering iron (conductor cross-sectional area 0.75 ~ 3.5 mm2 (AWG18 ~ AWG12) 30 seconds or less, and conductor cross-sectional area 5.5 ~ 14 mm2 (AWG10 ~ AWG6) 60 seconds or less)
(3) Apply solder and fill the gap between the contact and the core wires
(1) Screw the insulator firmly to the connector body (contacts for 80 A and 150 A should be installed with a contact wrench beforehand)(2) Tighten the lock screws (tighten the connector body and insulator to the extent that they do not loosen when rotated by hand)
(3) Tighten the clamp screw and attach the clamp saddle to the plug body
