Zero pressure accumulation — product never contacts adjacent product under pressure. Ten models available.
When a zone is occupied, the upstream zone stops completely. Products never touch under pressure. Critical for fragile cartons, totes, and cases.

24VDC brushless MDR technology. Energy efficient, quiet, simple wiring. The modern ZPA standard.
