Quadrios 23C490 Ring Terminal, 0.5-1.5 mm², Red, 100 pcs

For electricians and technicians wiring control panels, automotive harnesses, or marine electrical systems, the Quadrios 23C490 ring terminal provides a reliable crimp connection for stranded copper wires from 0.5 to 1.5 mm² (22 to 16 AWG). The red PVC insulation sleeve is colour-coded for quick identification of the wire size range, and the tin-plated copper body resists corrosion in damp or high-vibration environments.

Key specifications

• Wire cross-section: 0.5 – 1.5 mm² (22 – 16 AWG)
• Ring hole diameter: 3.2 mm (M3 stud)
• Material: Tin-plated copper, PVC insulation
• Colour: Red
• Quantity per pack: 100 pieces
• Max. voltage: 600 V
• Operating temperature: -10 °C to +75 °C
• Connection method: Crimp
• Insulation: Fully insulated
• Total length: 19.5 mm

Why choose it

The pre-insulated design speeds up assembly: no need for separate heat-shrink tubing, and the funnel entry guides the wire into the barrel for a consistent crimp. The red colour instantly tells you it is for 0.5–1.5 mm² conductors, reducing mix-ups on the bench or in the field.

Ideal use cases

• Terminating control wiring inside industrial cabinets
• Grounding connections in automotive and marine applications
• Low-voltage DC circuits up to 600 V

Good to know

Use a ratchet crimping tool with a red die set for a gas-tight joint. The tin plating allows soldering if required, though crimping alone is sufficient for most installations.
