The Siemens 6FX2001-2GF00, also known as the SINUMERIK Handheld Terminal HT 2, is a robust and ergonomic device designed for manual operation, setup, and diagnostics of machine tools and production systems. It features a precise handwheel with 100 detents per revolution, enabling fine adjustments of machine axes. Safety is paramount with an integrated EMERGENCY STOP button and two 3-stage enabling buttons. The terminal also includes two keyswitches for selecting operating modes or access levels, and two configurable LEDs for status indication. It connects to the control system via a durable 5-meter spiral cable, typically interfacing with Siemens connection boxes such as the 6FX2007-1AD03 or 6FX2007-1AD13.
