It serves as original OEM matching part for new AP800 panel assembly and direct replacement spare component for maintenance renovation of existing in-service control panels across diversified automation sectors.
Basic Information
Fixed official ordering part number is defined as 5AC800.EXT3-02, with unified overall dimension, embedded installation hole layout and proprietary internal bus connector definition fully matching reserved right expansion slot of all AP800 series panel specifications. This EXT3 series variant features mixed layout of programmable LED function keys, backlit ring keys and auxiliary shortcut keys differing from conventional EXT2 standard keypads, adopting dedicated internal bus to realize simultaneous 24VDC power supply and bidirectional digital signal communication with host panel, supporting plug-and-play without extra driver setup or complicated system parameter configuration. Lock-type anti-drop connector terminals effectively eliminate intermittent poor contact caused by long-time equipment oscillation and accidental external pulling force on wiring.
Outer enclosure frame is constructed from high-density natural anodized aluminum with anti-static and oil-proof surface finishing; front operation overlay uses integrated compression sealing molding to realize consistent IP65 front protection performance. Permanent laser marking of full model code, production batch number and unique individual serial number is arranged on rear casing to realize full-lifecycle quality traceability and standardized warehouse inventory management. All internal PCB, key switch assemblies and structural raw materials comply with EU RoHS hazardous substance restriction rules and international industrial flame retardant material standards. Final outgoing inspection covers full-key conduction verification, insulation withstand voltage test, dimensional fitting calibration and host compatibility confirmation to guarantee qualified delivery. Standard factory package contains only keypad main unit; mounting gaskets, fixing hardware and customized connecting cables require separate independent procurement according to project installation layout. The product maintains complete mechanical and electrical interchangeability with other EXT3 serial expansion keypads within 5AC800 platform.
Function and Positioning
Positioned as specialized right-side extended manual input terminal for AP800 HMI control architecture, the 5AC800.EXT3-02 cooperates with main touchscreen, left expansion modules and other peripheral fittings to build complete on-site human-machine interaction system for equipment startup debugging, real-time production monitoring and emergency fault disposal, applicable both for original supporting assembly of newly-manufactured automation machinery and damaged keypad replacement upgrade of old control cabinets.
For core operation functions, abundant programmable shortcut keys with built-in multicolor LED indicators enable one-touch rapid execution of equipment operating mode switching, fault alarm reset, display page jump and frequently-used parameter quick recall; embedded LED lamps display real-time activation status to facilitate operator identification under low-light workshop surroundings. Optimized key travel depth and pressing resistance are designed following industrial ergonomics to lower continuous-operation fatigue and improve field manipulation efficiency. Multi-stage filtering and shielding circuits are embedded inside internal PCB layout to suppress stray electromagnetic interference generated by nearby inverters, servo drivers and high-power motors, avoiding unintended key mis-trigger and signal distortion during instruction transmission to main control panel.
In environmental adaptability performance, fully sealed front panel effectively blocks splashing cutting fluid, floating dust and oil mist from penetrating into inner electronic circuits to prevent component short-circuit damage induced by pollutant accumulation. Reinforced internal component bonding and fixed framework avoid internal part displacement and solder joint detachment under persistent mechanical oscillation, supporting 24-hour non-stop continuous operation matching round-the-clock running mode of automated production and packaging lines. Modular structural design simplifies field disassembly and assembly steps greatly to shorten maintenance downtime during on-site component replacement.
Core Performance Parameters
For mechanical and keystroke performance, aluminum frame retains stable dimensional precision against occasional physical collision and long-term micro-vibration without casing deformation or mounting hole offset. Every individual key switch passes over one million pressing endurance certification to keep consistent rebound elasticity and stable conductive performance, free from key jamming or intermittent connection failure after long-period frequent daily operation. Keycap surface function marking adopts high wear-resistant printing pigment to prevent gradual fading after years of industrial usage; strict dimensional tolerance control enables seamless flush embedded installation on AP800 reserved panel cutout without secondary on-site trimming.
Regarding electrical specifications, the keypad draws rated low voltage power directly from host panel internal bus through matched connecting cable; built-in overvoltage, overcurrent, short-circuit and electrostatic surge protection circuit automatically cuts off power supply under abnormal electrical conditions to protect inner circuit and connected panel mainboard from overload breakdown. Optimized EMC-oriented PCB routing plus internal shielding layer design ensures stable signal transmission within complex industrial electromagnetic field environment; internal wiring conforms to international insulation safety standard to eliminate electric leakage hidden risk during normal installation and operation. Max total power consumption of the whole keypad is controlled within rated limit to reduce host panel load.
For environmental adaptability indexes, rated continuous working ambient temperature ranges from 0°C to +50°C; permissible short-term storage and transportation temperature covers -25°C to +60°C, applicable relative working humidity maintains 5%~95% under non-condensing condition to adapt regular control room and open-air production workshop climate. The product has passed authoritative high-low temperature alternating cycling test, damp heat aging inspection and specified vibration certification to sustain reliable performance in dusty, oily and temperature-fluctuating harsh field conditions. All plastic and composite structural accessories satisfy international industrial flame retardant safety criteria to promote overall application security.
General Matching Accessories
Standard separately purchasable supporting accessories include dedicated shielded interconnection cable of various customized lengths, elastic anti-vibration sealing gaskets, metal fixing screws and replaceable slide-in key label strips; 5AC800.EXTX-03 serves as matched label template accessory specially designed for EXT3-02 and EXT3-03 to realize customized function marking for each shortcut key. Shielded connecting cable with multi-layer braided shielding guarantees steady power and signal transmission in high-interference industrial environment, with different cable lengths selectable based on actual wiring distance; elastic sealing gaskets fill assembly gaps to enhance overall dustproof and splashproof performance while absorbing operation vibration from equipment.
Daily maintenance auxiliary parts include anti-static cleaning brush and soft lint-free wiping cloth for periodic surface upkeep; it is advised to implement regular cleaning every two to three months according to on-site dust and oil concentration level, while corrosive chemical solvent, sharp hard scraping tools and high-pressure water washing are strictly forbidden to avoid damage of front sealing layer, key switches and outer anti-corrosion coating.
This keypad can be flexibly combined with full-range 5AC800 series left expansion keypads, extension cover plates and assorted connecting cables to realize diversified customized HMI layout schemes; all optional spare accessories follow unified B&R production standard with cross-model interchangeability. It is recommended to reserve proper quantity of complete 5AC800.EXT3-02 spare units and vulnerable fittings such as gaskets and cables on customer site to achieve rapid full-set replacement upon component breakdown and minimize production halt duration caused by HMI accessory failure.
