Product Highlights
  • Ultra-slim 17.2 mm front section fits tight guards and small fixtures; neat cable routing.
  • Self-diagnostics with short-/over-current protection and clear indicators simplify troubleshooting.
  • ≤15 ms typical response helps reduce ISO 13855 safety distance while maintaining productivity.
  • ≥10,000 Lux immunity with filtering to suppress flicker and stray light; stable in welding glare.
  • IP65 enclosure; standard M12/aviation connectors and brackets for quick mounting.
  • Meets the intent of IEC 61496-1/-2; integrate with a safety relay/PLC for higher PL/SIL architectures.

Values consolidated from the supplied DQZ manual pages; if any difference exists, the official datasheet and delivered certificates prevail.

Resolution & Application Guide
Resolution (K)Typical Application
10 / 14 mmFinger protection (assembly, fixtures)
20 / 25 / 30 mmPalm / hand protection, guarded access openings
40 / 80 mmArm/body presence, aisle and perimeter guarding

Protective height H = (n − 1) × K. Overall length L = P + H + J + 24 (12 mm allowance at each end). P/J depend on K; see the spec tabs below.

Typical Applications

  • Presses / shears / press brakes: 10–30 mm suit hand protection; fast response supports shorter S-distance.
  • Robot cells & assembly fixtures: finger/palm detection with interlocked safety loop; compact to retrofit.
  • Packaging / logistics: 40–80 mm for aisle, pallet zone and presence detection.
  • General machinery: integrate with a safety relay/PLC for stop, interlock and EDM monitoring.

Safety distance reference (ISO 13855): S = K × T + C, where T is machine stopping time.
