Select sensors for warehouse and logistics automation by process point, not by product catalogue: define each detection point (pallet presence at transfer, carton counting on a sorting lane, stacker-crane positioning, rack-location verification), characterize the target (wood/plastic pallet, cardboard, reflective stretch-wrap, transparent packaging), the speed and the mounting conditions, then match each point to a detection technology. KJT Sensors covers these points with photoelectric, ToF, laser distance and vision product families.
Design by process point. A warehouse detection problem is a set of distinct points — transfer, sorting lane, positioning, verification — each with its own target, speed and reliability requirement. One sensor type rarely serves all of them.
The target surface decides the technology. Cardboard, wood, plastic, reflective stretch-wrap and transparent film behave differently; reflective wrap and clear packaging are the two most common causes of unreliable detection on logistics lines.
Positioning is a measurement task, not a detection task. Stacker-crane and shuttle positioning requires a distance sensor with stated repeatability and update rate — a presence switch is the wrong tool.
Validate with real loads at real speed. Stretch-wrap, damaged pallets and mixed cartons must appear in the acceptance test, at full line speed.
