Product Description:

The 1911-2301-702D-6037D Floppy Disk Drive Unit is a compact panel mounted device designed for integration into CNC machines. It is specifically tailored for OKUMA OSP7000 systems. It offers dependable data transfer and storage functionality using established floppy drive interface standards and mounting configurations.

The 1911-2301-702D-6037D floppy disk drive unit is built to fit a standard 3.5" floppy bay. It measures approximately 102 mm wide, 25 mm high and 146 mm deep. Its front panel includes a single disk slot, a manual eject button and a flap that protects the insertion slot from debris. The side mount screw holes allow for secure and stable chassis installation. The drive uses a standard 4 pin Berg power connector. The pinout for the connector follows the conventional layout: Pin 1 supplies + 5 V, Pins 2 and 3 are ground and Pin 4 provides + 12 V. For data communication, the unit is equipped with a 34 pin IDC ribbon cable connector which connects to the host controller. This ensures direct compatibility with older control hardware. An integrated custom control PCB manages the drive operations. The onboard logic includes a configuration dial and a set of DIP switches or jumpers. These components allow technicians to manually set or adjust the operational parameters of the drive.

The 1911-2301-702D-6037D floppy disk drive unit supports 1.44 MB capacity using 3.5” 2 HD disks. It operates at a rotational speed of 300 RPM. Track density is rated at 135 tracks per inch and the sectoring scheme follows the standard 512 bytes per sector with 18 sectors per track. This format ensures compatibility with legacy systems requiring deterministic data structure. The onboard logic board maintains consistent read/write operations and reliable disk access during CNC machine operation.
