Product Description:
The 5A5001.19 is a rotating magnetic hard disk manufactured by B&R Automation for the 5A5 Hard Disks series. Designed for industrial PCs and programmable controllers, the drive provides persistent mass storage for system software, recipe data, and event logs within automated production lines. Its role is to supply deterministic local data access without dependence on external networks in environments where controller uptime is critical. It occupies a standard 2.5-inch bay, allowing easy integration into compact control cabinets. This form factor also suits control systems where available installation space is limited.
Formatted capacity stands at 40 GB, distributed across 78,140,100 user sectors with 512 bytes each. An 8 MB cache buffers read and write bursts before the data is committed to the platters, and the ATA-6 parallel interface supports host transfers up to 100 MB/s. Internally, media throughput peaks at 45 MB/s as magnetic encoding passes beneath the heads spinning at the nominal speed. Average access latency is 12.5 ms, while mechanical positioning ranges from a minimum seek of 1 ms to a worst-case seek of 22 ms. These timings indicate how quickly a controller task can recall scattered files or log entries during normal operation.
The spindle stabilizes at 5,400 rpm ±1%, and the drive reaches ready status in 3 s from power-on, supporting quick machine restarts after service. Continuous operation is specified up to 5,000 m altitude, so ventilated enclosures on high platforms remain within the drive’s operating range. A SMART health monitor provides predictive failure flags, and the fixed adapter mounting minimizes displacement under vibration. These features support reliable storage behavior in automated equipment that depends on local data retention and steady startup performance.
