Basic Information
The fixed official ordering part number is 5AC800.EXT3-03, featuring unified overall dimension, embedded installation hole layout and proprietary internal bus pin definition fully matching the reserved right expansion mounting position of all AP800 series panels. Differentiated from EXT3-02 variant, this model optimizes internal key layout and LED indicator configuration to adapt to multi-axis motion control and frequent shortcut operation scenarios of processing equipment. The keypad adopts exclusive internal bus connection to realize simultaneous low-voltage DC power supply and bidirectional digital signal transmission with host panel, supporting plug-and-play without extra driver installation or complicated parameter setup. Every connector terminal is fitted with locking anti-drop structure to avoid intermittent poor contact caused by long-time equipment vibration and accidental external pulling force on wiring harness.
The outer enclosure frame is made of corrosion-resistant anodized aluminum with anti-static and oil-proof surface treatment; integrated compression sealing design of front face provides reliable dust and splash protection for internal electronic components. Clear model marking, production batch code and unique serial number are permanently printed on the rear housing for full lifecycle traceability and standardized warehouse stock management. All PCB substrates, key switch assemblies and structural raw materials comply with RoHS hazardous substance restriction requirements and international industrial flame retardant criteria. Final outgoing inspection covers complete key function test, insulation withstand voltage detection, dimensional fitting check and host compatibility confirmation. Standard factory package only contains keypad main body; shielded connecting cables, mounting brackets and elastic sealing gaskets need separate procurement based on actual field installation demands. The product features full mechanical and electrical interchangeability with other EXT3 serial keypads within 5AC800 product platform.
Function and Positioning
Positioned as professional right-side extended operation terminal of B&R AP800 HMI system, the 5AC800.EXT3-03 cooperates with main touchscreen, left expansion keypads and extension covers to build complete industrial human-machine interaction system, applicable for original supporting assembly of newly manufactured automation equipment and direct replacement maintenance of damaged right expansion operation units on existing control cabinets.
In terms of core operation function, multiple programmable shortcut keys with embedded LED indicators support one-touch execution of equipment operating mode shift, fault alarm reset, display page switching and frequently-used parameter quick access; real-time status feedback from built-in LED lamps helps operators confirm triggered functions under dim production environment. Key stroke depth and pressing force follow industrial ergonomic design to reduce fatigue during long-shift continuous manual operation and improve on-site manipulation efficiency. Multi-layer filtering and shielding circuits are embedded inside internal PCB to restrain stray electromagnetic interference from nearby inverters, servo drives and high-power motors, effectively preventing unintended key mis-trigger and instruction signal distortion during data transmission to main control panel.
In terms of environmental protection and continuous running performance, fully sealed front panel blocks splashing cutting fluid, floating metal debris and workshop oil mist from penetrating into inner circuits, avoiding short-circuit damage caused by pollutant accumulation. Reinforced internal component fixation with shockproof bonding prevents internal parts displacement and solder joint detachment under long-term mechanical oscillation, enabling 24-hour non-stop continuous operation matching round-the-clock running mode of automated production and packaging lines. Modular split structure simplifies disassembly and assembly procedures for field equipment upgrade and routine overhaul.
Core Performance Parameters
For mechanical and keystroke performance, aluminum frame maintains stable dimensional accuracy against accidental collision and long-term micro-vibration without casing deformation or mounting hole displacement. Each key switch passes over one million pressing endurance testing to retain consistent rebound elasticity and stable conductive performance, free from jamming or intermittent connection failure after long-term frequent usage. Keycap function symbols adopt high abrasion-resistant printing technology to avoid fading after years of daily industrial operation; precise dimensional tolerance ensures seamless flush embedded installation on AP800 reserved panel cutout without secondary field trimming.
Regarding electrical performance, the keypad draws rated low-voltage DC power directly from host panel internal bus via matched dedicated cable. Built-in overvoltage, overcurrent, short-circuit and electrostatic surge protection circuit automatically cuts off power under abnormal electrical conditions to protect internal keypad circuit and connected mainboard from overload damage. Optimized EMC-oriented PCB wiring plus internal shielding layer design guarantees stable signal transmission within complex industrial electromagnetic field; internal wiring satisfies international insulation safety specification to eliminate electric leakage risk during installation and normal operation.
For environmental adaptability indicators, rated continuous working ambient temperature ranges from 0°C to +55°C; allowable storage temperature spans from -25°C to +70°C, applicable relative working humidity is 5% to 95% under non-condensing condition to adapt conventional control room and open production workshop climate. The product has passed formal high-low temperature alternating cycle test, damp heat aging test and random vibration certification to operate reliably in dusty, oily and temperature-fluctuating harsh field conditions. All plastic and composite structural materials meet international industrial flame retardant safety standards to promote overall application security.
