Product Description Size: 20pcs, 50pcs Main Specifications: 1. Operating Environment: Temperature -30°C ~ +70°C 2. Relative Humidity: ;85% Air pressure: 70-106kPa 3. Insulation resistance: Insulation resistance between any two terminals ≥ 1 × 10MΩ (normal temperature and humidity method) 4. Contact resistance: The contact resistance between the wiring board and the conductor is ≤5 mΩ 5. Dielectric strength: A DC voltage of 2000V (or 1400V) is applied between the metal wires of the connected module and the insulating shell (sleeve, leather), and the module will not be damaged within 1 minute or lead to a spark failure. Feature： 1.Material:: High quality ABS material | Fast, Safe, Reliable, After installation, vigorously tighten wire until it is locked, then cut the wire. 2.Easy Assembly:: Up to 3 connectable wires | Application: 0.5mm² to 1.5mm² wire diameter, Dimensions: Depth = 24mm Width = 23mm Height = 17mm (through connection). 3.Waterproof Design:These connectors are fully waterproof, resins, to protect against moisture and provide a firm connection. 4.PREMIUM BUILT:： Our electrical pigtail connectors are made of flame retardant nylon and their special silicone gel keeps the moisture away from the connection. The internal construction of brass elements ensures good conductivity and is tinned to prevent corrosion. 5.Application:: Widely used in lighting, power and automobile wiring, for motor, electrical control, power supply, household appliances, Lighting and mechanical wire connectors. 6.FAST, SIMPLE AND EASY TO USE:： Just press - no peeling or twisting. Simply insert the wires into the pigtail's electrical connector and crimp the blue cap with a crimping tool. This saves time and ensures a reliable and permanent connection.
