Caterpillar 2668576 Speed Sensor Assembly

The Caterpillar 2668576 speed sensor is a Hall-effect device designed to monitor torque converter output speed on heavy machinery. It operates at a rated voltage of 14V with a supply current of 30mA. The sensor features a 3-pin DT06 plastic connector interface and an overall body length of 55.88 mm (2.2 in) with a lead wire length of 320 mm (12.6 in). Construction materials include alloy iron, alloy brass, gray iron, and carbon steel for durability in harsh mining and construction environments. This sensor group is engineered as a direct replacement for torque converter output speed detection on Caterpillar off-highway trucks including the 785C, 789C, 770G, 772G, and 773G series, as well as 994F and 994H wheel loaders. It is compatible with Caterpillar C9, C13, and C15 engine platforms including industrial variants CX31-C13I, TH31-E61, TH35-C13T, and TH35-C15T. The unit weighs approximately 0.1 kg.
