The CM1A-R-12V is a compact, high-capacity automotive relay designed for robust load switching. This sealed, plug-in type relay operates with a nominal coil voltage of 12V DC and features a 1 Form A contact configuration with an internal resistor. It is capable of switching a normally open load of 35A at 14V DC. Its small size, measuring 20mm x 15mm x 22mm, and use of the international standard ISO terminal arrangement make it highly versatile. Common applications include controlling fan motors, heaters, headlamps, air compressors, and defoggers in automotive systems.
