SZ196ZPA

Zero Pressure Accumulator Smart Zone® Medium Duty Conveyor

The SZ196ZPA applies Smart Zone® proprietary photoelectric sensing for zero pressure accumulation, replacing traditional sensor rollers with photo eyes to detect product presence without requiring a minimum load weight. This medium duty accumulator safely queues cartons, totes, and similar packages using zone singulation while eliminating back pressure, extending reliable accumulation to products that may not engage roller-based sensors effectively.

Its mechanical design aligns with typical medium duty conveyor specifications, supporting loads up to roughly 125 pounds per foot and leveraging a consistent roller platform compatible with modular system elements. The integration of photoelectric sensors simplifies installation and enhances detection precision across varied product types, making this configuration appropriate for distribution, fulfillment, and manufacturing facilities that handle mixed-weight goods.

Applications

  • Product buffering between processes
  • Merging and singulation of cartons or totes
  • Accumulation before sortation, labeling, or inspection
  • Controlled release into packaging or palletizing equipment
  • Staging product for shipping and order fulfillment

Industries

  • Distribution and fulfillment operations
  • Manufacturing and assembly lines
  • Packaging and material handling systems
  • Food and beverage processing
  • Automotive and industrial manufacturing
