Models follow the format DQSA NN/K-H, e.g. DQSA04/40-120. Choose pedestal and mirror kits per cell layout.
Typical Applications
Robot cells / rotary tables: 3- or 4-side perimeter with pedestal posts and mirrors.
Packaging & logistics: long aisle single-side guarding up to 40 m.
Machinery periphery: presses, shears, palletizers; interlocked with safety relay/PLC.
Flexible retrofits: fast installation with pedestal kits; easy alignment via visible pointer.
Use ISO 13855 to calculate the safety distance S = K × T + C (T: machine stopping time).
