The 1548-103 is a black binding post assembly designed for high-current electrical connections in laboratory and industrial applications. It features a brass body with nickel finish and polyamide insulators (top and bottom) to provide electrical isolation and durability. The assembly includes a red polyamide knob, flat and split washers, and steel nuts with nickel finish, all configured with a 1/4-28 UNF thread stud for secure panel mounting. The post is designed for panel cutout dimensions of 0.433 inches square with a panel thickness tolerance of 0.010 to 0.110 inches, and the stud includes a deep hole (0.138 × 0.236 inches) for enhanced mechanical retention. This binding post is commonly used in test equipment, power distribution panels, and high-current measurement setups where reliable, repeatable connections are essential.
