SICK Dx35 DR35-B15522 Laser Distance Sensor

The Applications for SICK Dx35 DR35-B15522

1.Pallet Shuttle Precision Stop
High-throughput warehouses rely on pallet shuttles that must brake at the same point every trip, regardless of dust, box color, or ambient glare. Mount the DR35-B15522 inline with a small reflective marker on the rack rail. Its time-of-flight measurement gives an absolute distance signal that isn’t fooled by packaging changes, so the shuttle decelerates smoothly and lands exactly on target. Fast response supports tight cycle times, while IO-Link lets maintenance teams nudge the stop window from the PLC after a rail swap or wheel wear. The result: fewer bumps, quieter operation, and consistent pallet positioning without constant mechanical readjustment.

2.Stretch-Wrapper Infeed Triggering
Packaging halls fight false trips from shiny film, dented pallets, and shifting loads. The DR35-B15522 solves this by sensing distance to a small control marker beside the conveyor rather than relying on the pallet’s surface. As each load passes, the sensor produces a crisp, repeatable trigger for wrap start, knife actuation, or clamp release. Millisecond-level updates keep timing tight when line speed changes. Push-pull outputs simplify wiring into existing I/O, and IO-Link allows quick parameter tweaks during product changeovers. Operators see fewer misfires and less film waste, while maintenance gains stable, teach-once behavior that survives glare, dust, and vibration.

3.AGV/AMR Docking & Charging Alignment
Autonomous carts often miss charging pins or tooling nests by a few millimeters when floors shift or bumpers deform. A DR35-B15522 aimed at a compact high-contrast target on the dock provides an absolute approach distance that ignores paint color and scuffs. The sensor’s “in-window” output becomes the final approach cue, while the controller reads distance over IO-Link for fine positioning. Because the optical target is inexpensive and rugged, every bay can be equipped without adding bulky hardware. Dock cycles become faster and more reliable, battery connections are cleaner, and robots spend more time moving product instead of hunting for alignment.

4.Conveyor Spacing, Presence & Print Verification
Mixed SKUs on belts confuse diffuse sensors that depend on color or gloss. By measuring distance to a narrow reference strip, the DR35-B15522 detects small changes as cartons enter the sensing zone, providing reliable presence and accurate gap measurement for printers, labelers, and sorters. The approach works across matte cartons, shiny pouches, and shrink-wrapped trays. With quick output timing, the PLC can place lot codes on the same panel every time, even as throughput climbs. If belt tension or product height changes, parameters are adjusted remotely via IO-Link—keeping marks legible, rejects low, and downstream devices synchronized without mechanical flags.
