What wire sizes do these 3M Scotchlok IDC connectors fit?

These 3M Scotchlok IDC 558 connectors are designed to accommodate wires ranging from 22 to 16 AWG, suitable for both solid and stranded conductors. Ensure your wire gauge falls within this range for a secure and reliable connection in your automotive, marine, or low-voltage electrical projects.

Are these 3M Scotchlok connectors suitable for high-voltage applications in India?

These connectors are rated for 600V for building wire and 1000V for signs and fixtures. While robust for low-voltage applications, they are not intended for high-voltage mains electrical work. Always consult a qualified Indian electrician for mains power installations and use components certified for Indian electrical standards.

How do I use these 3M Scotchlok IDC connectors?

These connectors feature self-stripping insulation. Insert the stripped ends of two wires (22-16 AWG) into the connector slots. Use a proper crimping tool to press down the brass IDC (Insulation Displacement Connector) tab, which pierces the wire insulation to create an electrical connection and secure the wires.

What is the shelf life of these 3M Scotchlok connectors?

When stored in their original factory-sealed packaging, these 3M Scotchlok connectors have a shelf life of 5 years from the date of manufacture. Ensure they remain dry and protected from extreme temperatures to maintain their integrity.

Are these 3M Scotchlok connectors RoHS compliant?

Yes, these 3M Scotchlok IDC 558 connectors are RoHS Compliant, meaning they adhere to restrictions on hazardous substances, ensuring a safer product for industrial and occupational use.

Trust in 3M's engineering for secure, long-lasting connections that meet stringent UL, CSA, and RoHS standards.

Ideal for Automotive & Low-Voltage, Skip for Mains

These connectors are perfect for automotive, boat, RV, and low-voltage building wiring, signal systems, and fixtures. They are designed for wire gauges 22-16 AWG. However, they are rated for a maximum of 1000V and are not suitable for high-voltage mains electrical work or applications requiring specific Indian electrical codes not met by US certifications. For mains power, always consult a qualified Indian electrician and use locally certified components.

How to use

Strip approximately 1/4 inch (6mm) of insulation from the ends of the two wires (22-16 AWG) you intend to connect. Ensure the exposed copper is clean and free from damage. — Prepare Wires
Insert one wire end into one slot of the red 3M Scotchlok IDC connector and the second wire end into the other slot. Ensure the wires are fully seated within their respective channels. — Insert Wires
Using a suitable crimping tool (e.g., 3M's recommended crimpers), firmly press down the metal IDC tab within the connector. This action pierces the wire insulation, creating a secure electrical connection and locking the wires in place. — Crimp Connection
Gently tug on the wires to ensure they are securely held within the connector. Check that the IDC tab is fully depressed and the connection is stable for reliable electrical continuity. — Verify Connection
