Product Description:

The 5AC901.FF01-02 front cover is manufactured by B & R Automation for the 5AC CNC Addon Modules series. Designed as an accessory for the company’s modular computer-numerical-control hardware, the cover blocks unused card openings so that sensitive circuitry remains isolated from airborne dust and incidental finger contact. When installed, it helps retain the original cooling air path inside the rack, an important factor for temperature-controlled operation of servo drives and logic boards. Tool-free mounting lets a technician remove the faceplate quickly during service without disturbing adjacent modules, minimizing downtime on automated production lines.

The enclosure’s physical profile is defined by a depth of 14 mm, a height of 264 mm, and a width of 82 mm; these dimensions match a single 5AC rack bay so the panel sits flush with neighboring modules. Its housing is molded from Plastic, a lightweight material that resists common industrial cleaning agents. The surface is finished in Dark Gray, reducing reflections and providing visual contrast to status LEDs on adjacent electronics. Together, these characteristics help the installed cover preserve ingress protection and maintain the electrical clearance required at the backplane.

Because the panel occupies exactly 1 slot, technicians can leave that position available for later expansion while still closing the rack opening. The part is classified as a Front Cover, meaning no active circuitry or ventilation grids are included. Its surface is Dyed rather than painted, so scratches do not reveal a lighter substrate during service.  These attributes complement the dimensional profile described above and complete the accessory’s protective role.
