Gustav Klauke GmbH 47212 Electrical Terminals with Tin-Plated Copper and Polypropylene, 1.7 mm Diameter, Black, 1000 Pieces

The Gustav Klauke GmbH 47212 electrical terminals are designed for secure and reliable wire termination in various electrical installations. Manufactured with high-quality copper and finished with tin plating, these terminals offer enhanced durability and protection against corrosion. Each connector features an integrated polypropylene insulation collar in black, which provides additional safety and strain relief at the connection point. Supplied in a bulk pack of 1000 pieces, this product is well-suited for high-volume wiring tasks, maintenance work, and professional electrical engineering projects.

Advantages

The use of tin-plated copper ensures optimal electrical conductivity and long-term resistance to environmental factors, minimizing the risk of signal loss or connection failure. The polypropylene insulation collar facilitates safe handling, prevents accidental contact with bare conductors, and supports the wire insulation to protect against bending stress. Their standardized dimensions allow for consistent installation results, making them an efficient choice for structured wiring setups.

Suitable for

• Professional electrical installations and wiring
• Industrial control panel building
• Maintenance and repair of electrical equipment
• High-volume wiring tasks requiring reliable termination

When it may not be suitable

These terminals are not intended for use with wire diameters that fall outside their specified range, as an improper fit can lead to insecure contact or insulation failure. They are also unsuitable for high-temperature environments that exceed the thermal limits of the polypropylene collar.

Key specifications

• Material: Copper with tin plating
• Insulation material: Polypropylene (PP)
• Product colour: Black
• Diameter: 1.7 mm
• Stripping length: 1.8 cm
• Quantity per pack: 1000 pieces

How to use

To use the electrical terminals, first strip the wire insulation to the recommended length of 1.8 cm to ensure the conductor fits properly within the barrel without excess exposed copper. Insert the stripped stranded wire fully into the metal tube of the terminal until the wire strands reach the end of the barrel and the insulation collar rests against the wire jacket. Secure the connection using a suitable crimping tool designed for this terminal size, applying steady pressure to achieve a permanent mechanical and electrical bond.

What to consider before purchase

• Verify that the 1.7 mm diameter matches the gauge of the wires being used in your specific application
• Confirm that the black polypropylene insulation meets your color-coding or visual requirements
• Check that you have the appropriate crimping tool compatible with these terminals

Usage recommendations: Always use a calibrated crimping tool suitable for the specific terminal size to ensure a secure, gas-tight connection that prevents oxidation and loosening over time. Store the unused terminals in a dry place to protect the metal components from moisture and environmental degradation.
