Product Description:

The BTM03.1-NA-TA-TA-VA-SA-HA-2EA-FW belongs to the BTM03 Machine Operator Panels series manufactured by Bosch Rexroth Indramat. This handheld panel is intended for CNC and general automation tasks where an operator must directly adjust feed rates, spindle speed, and axis position while remaining within a protective working envelope. By combining tactile keys, a handwheel, and integrated safety circuitry, the unit acts as the primary human-machine interface between machining centers or motion controllers and shop-floor personnel.

Safety and motion overrides are handled by several hardware elements. The emergency stop mechanism uses a Locking Emergency Off pushbutton that physically latches when pressed, and its circuit is routed through two redundant 2 N/C contacts so the control system detects any broken wire or contact failure. Rapid feed adjustments are handled through a rotary switch that provides 16 lock positions, allowing precise incremental scaling without accidental drift. Manual jog or fine positioning is executed with a handwheel that features a Locking Turning Knob, preventing unintended rotation when the knob is pulled out. Each handwheel step is converted to numerical input according to a linear scale of 0 to 100, giving predictable resolution for axis movement.

Local command entry is managed by a key module rated at IP65, so the front face resists dust and low-pressure water jets when the panel is mounted on machining equipment. Operators have direct access to 15 keys with LED backlighting, and the Short Stroke switch design shortens actuation travel for faster response and lower wear. Behind the membrane, the master board offers 16 inputs, 16 outputs for connection to bus couplers or proprietary control cables. A second rotary switch is provided for spindle override, allowing motion settings to be adjusted without reprogramming.
