The Mitutoyo 12AAA807 RS-232C cable is used to transfer data between the Mitutoyo LH-600D linear height gauge and a computer. The cable measures 80" (2m) in length, and has two nine-hole DB9 female-to-DB9 female connectors. The Mitutoyo RS-232C cable is an accessory for use with the Mitutoyo LH-600D linear height gauge, which is a high-performance 2D measurement system.

Height gauges, sometimes referred to as gages, are precision measuring instruments that travel on a vertical column (also called the beam) to measure and/or mark the vertical distance from the base of an object in fine units. The vertical position of the gauge and its attached pointer are changed by turning a calibrated screw, or one or more feed wheels. Recorded rotations are read from a scale, a dial, counters, and/or an electronic display. A screw clamp holds the pointer to the gauge. The pointer is typically sharpened to act as a scriber, and can be used to mark a position on a workpiece by scratching its surface. On compatible units, the scriber may be replaced by an electronic touch-signal probe. Height gauges are typically used in manufacturing, machining, and mechanical engineering.

Mitutoyo manufactures precision measuring tools, metrology equipment, and related systems. The company, founded in Tokyo in 1934, formed Mitutoyo America Corporation in 1963 with headquarters in Aurora, IL.
