【Cable Terminal Kits】: The set of 1640 crimp connectors includes 590 pre-insulated cable ferrules and 1050 uninsulated crimp terminals. Interface type: AC/DC. Operating frequency: low frequency. 【Uninsulated Butt Connectors】: Uninsulated electrical terminals of 5 types: 0.5mm² (400 pieces), 1.00mm² (200 pieces), 1.5mm² (200 pieces), 2.5mm² (150 pieces), 8mm length. 4.00mm² (100 pieces), 9mm length. 【Pre-Insulated Crimp Terminals】: Insulated wire ferrules with PVC heads in 5 types: red 0.5mm² (200 pieces), blue 1.00mm² (150 pieces), black 1.5mm² (100 pieces), yellow 2.5mm² (80 pieces), green 4.00mm² (60 pieces). 【Application】: Uninsulated crimp ferrules effectively prevent wire ends from becoming exposed or broken. Copper wire ferrules offer good electrical and thermal conductivity, providing reliable connections. These ferrules, designed with an insulating flare, facilitate wire insertion. 【Tin-Plated Copper】: These electrical end connectors are made of red copper, tin-plated to prevent oxidation and rust, making them more durable. Widely used for electrical projects, workshops, automotive electricians, machinery, cars, trucks, motorcycles, etc. 【How to Use】: Remove the wire core from the sleeve. The stripping length should be as long as the metal ferrule of the crimping tool. Place the entire core inside the ferrule of the wire end without exposing it, then crimp the crimping tool. Before doing so, please adjust the crimping tool according to the thickness of the wire core.
