Product Description:
The 5A2001.05 floppy disk drive is produced by B & R Automation as part of the 5A2 Floppy Disk Drives series. This external storage device transfers application files and diagnostic logs in industrial automation cells that still rely on floppy-based data exchange. Mounted directly on a control panel, the drive allows program loading from the plant floor, and its black front panel blends with typical HMI layouts found in legacy cabinets. Because it is an external drive rather than a board-level storage device, access to the disk slot remains available from the front of the cabinet.
The drive accepts double-sided diskettes with a formatted capacity of 1.44 MB, giving enough space for application files and multiple parameter sets. It uses the familiar 3.5 in form factor, so the unit works with commonly available media used in older control systems. A Centronics cable interface carries the data signals, while a separate 25-pin DSUB connector handles power and control lines. Separating the data path from the power and control connection helps keep wiring straightforward in older automation layouts. Electrical demand stays low at only 2.9 W, which helps limit heat rise inside sealed enclosures and allows the drive to share existing 24 V supply rails. Front-side cutouts of 68 + 0.7 mm in height and 138 + 1 mm in width guide panel fabrication so the bezel sits flush once secured.
The housing measures 144 mm across, stands 72 mm high, and extends 163 mm deep, giving clear boundaries when arranging dense operator stations. A maximum cable reach of 1.8 m lets the drive be positioned a short distance from the controller without signal degradation, which helps keep internal harness routing orderly. The depth should also be considered when space behind the panel is limited by wiring ducts or neighboring modules. Installation screws lock into the control-panel frame, and the stated mounting style allows direct panel installation without additional brackets. The black front panel also keeps the visible face consistent with other dark cabinet-mounted interfaces.
