The PHOENIX CONTACT C-SCFFI 6/6,3X0,8 insulation sleeve is a critical component for ensuring secure and reliable electrical connections. Designed for 6.3 x 0.8 mm plugs, this sleeve provides full insulation and is characterized by its yellow color and robust construction. The hard-soldered crimping zone guarantees maximum conductor pull-out forces when used with compatible CRIMPFOX pliers, while the 'EASY ENTRY' system simplifies conductor insertion. Constructed from brass with a tin-plated coating and a PA insulating material, this sleeve is halogen-free and suitable for a wide range of industrial applications requiring durable and insulated connections. Its operating temperature range of -20°C to 105°C ensures reliable performance in demanding environments.
