Tổng quan

YOCL Điện SP Series Color-Coded Screw-On Wire Connectors join two or more electrical conductors using a twist-on connection. Each connector combines a Nylon 66 insulated housing with an internal galvanized spring-steel element.

The spring grips the prepared conductors as the connector is twisted into position. Five models use gray, blue, orange, yellow and red housings to distinguish sizes. SP connectors are suitable for general electrical wiring, building installations and electrical equipment within the specified -20°C to +100°C operating range.

Tính năng

Screw-on connection: Joins conductors by twisting the connector into position.
Nylon 66 insulation: Surrounds the internal connection with a molded insulating housing.
Galvanized spring steel: Provides the internal conductor-gripping element.
Color-coded models: SP1 gray, SP2 blue, SP3 orange, SP4 yellow and SP6 red.
No crimping required: Uses a twist-on connection method.
Model-specific conductor combinations: Listed minimum and maximum combinations use mm² × conductor count.

Hướng dẫn lựa chọn

Select the connector using the listed conductor cross-sections and quantities together with the model’s dimensions. For example, SP3’s listed maximum combination, 1.5 × 3 + 1 × 1, means three 1.5 mm² conductors plus one 1 mm² conductor.

Use the model-specific combinations when selecting a connector. Housing color identifies the model: gray for SP1, blue for SP2, orange for SP3, yellow for SP4 and red for SP6.
