The Applications

1. Forklift and Narrow-Aisle Lift Height Control

In modern warehouse automation, accurate fork height sensing is vital to prevent damage and ensure efficiency. The BKS09-ATBM0520 excels in this role by delivering precise lift height feedback through its absolute SSI interface. Its compact structure fits seamlessly into confined mast designs, while ±0.7 mm linearity and ≤ 0.15 mm repeatability guarantee reliable performance. With its flexible steel wire and strong aluminum housing, it endures continuous lifting motion and vibration, maintaining stable data output for precise pallet stacking and retrieval in high-density storage environments.

2. Vertical Positioning in Automated Storage and Retrieval Systems (AS/RS)

In tall AS/RS warehouse towers, the BKS09-ATBM0520 offers reliable vertical travel measurement for shuttles and lifts. Its 5 m measuring range and absolute position output provide accurate feedback from the first power-on—no homing move required. Designed for fast motion, the unit’s spring-driven wire and aluminum housing handle frequent cycles with minimal wear. This ensures smooth bin retrieval, consistent stopping points, and reduced downtime in automated logistics environments, where continuous operation demands dependable feedback devices.

3. Press and Stamping Stroke Monitoring

In metal forming and stamping presses, accurate stroke monitoring determines product quality and tooling consistency. The BKS09-ATBM0520 measures slide or ram displacement precisely, translating mechanical motion into high-resolution digital data. Its robust housing and resistance to high acceleration (≤ 20 m/s²) ensure stable readings under heavy vibration. The unit’s repeatability of ≤ 0.15 mm enables early detection of misalignment or wear, improving safety and reducing unplanned maintenance in demanding manufacturing environments.

4. Telescopic Boom and Outrigger Extension Feedback

Mobile cranes, lifting platforms, and construction booms require exact measurement of extension and stabilization lengths to maintain balance and load safety. The BKS09-ATBM0520 provides real-time positional data through its SSI output, tracking boom or outrigger movement with millimeter accuracy. Its durable, flexible steel wire withstands outdoor operation and repeated motion cycles, while the IP52 protection guards against dust and moisture. The result is improved load monitoring, enhanced operational safety, and reliable performance even in harsh on-site conditions.
