Industrial Sk 18RAD-18277 Relay Contact Assembly

18RAD-18277 is a red nylon-insulated, fully enclosed female quick-disconnect contact from the Sta-Kon (Thomas & Betts / ABB) line, sized for 22–18 AWG copper conductors. The brass contact body is tin-plated, while the insulating portion is nylon (PA), delivering a crimped, fully insulated connection. The receptacle accepts a 0.187-inch (4.75 mm) wide, 0.020-inch (0.51 mm) thick tab and has an overall length of 0.89 inches (22.6 mm). This UL E66716-listed, RoHS3-compliant terminal is designed for tool-free connections to matching male tabs on terminal blocks or boards, enabling quick, removable connections in wiring harnesses and panel assemblies that use Sta-Kon 187-series interfaces. The red insulation aids identification and helps prevent unintended contact, while the durable copper/tin-plated contact and nylon body support reliable performance in industrial wiring applications requiring standardized, removable copper-to-tab connections.
