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).
Frequently Asked Questions
Is the DQSA an area safety light curtain or a perimeter guarding system?
The DQSA is a perimeter-guarding light curtain that uses reflector mirrors to bend the beam around 2, 3 or 4 sides of a robot cell or work area. With 40 mm or 80 mm beam spacing it provides body/area presence detection rather than fine finger protection, making it ideal for fencing off the perimeter of large hazardous zones.
What detection range does the DQSA cover with reflectors?
Typical reach is single-side ≤ 40 m, dual-side (L-shape) ≤ 20 m, triple-side (U-shape) ≤ 15 m and quad-side (O-shape) ≤ 12 m, achieved with proper mirror alignment. Protection height follows H = (n − 1) × K, where n is the beam count and K is the 40 or 80 mm spacing, so you can build perimeters over 3 m tall.
How do I calculate the ISO 13855 safety distance for the DQSA?
Use S = K × T + C from ISO 13855, where K is the approach speed (1600 or 2000 mm/s), T is the total stopping time including the curtain's < 15 ms response, and C is the intrusion penalty based on resolution. With 40/80 mm spacing the DQSA detects body presence, so size C for whole-body access and verify the mounting distance on site.
Can the DQSA replace a Keyence, SICK or Omron perimeter scanner setup?
For fixed perimeter guarding it is a cost-effective alternative to multi-sided light curtains or laser scanners. It complies with IEC 61496-1/-2 and EN 61496-3:2019 TYPE 4 and EN 13849-1, offers dual NPN/PNP outputs, and integrates with a safety relay or safety PLC using EDM, matching the interfaces of common Keyence/SICK/Omron systems.
What ingress protection and ambient light immunity does the DQSA have?
The DQSA is rated IP65 with aluminum posts and reinforced ABS caps for harsh workshops, and offers ambient light immunity ≥ 10,000 Lux at incidence ≥ 5°. Its EMC design resists flicker, welding-arc light and stray reflections, and it operates from −10 to +50 °C, suiting presses, palletizers and welding cells.
