DQE Safety Light Curtain Selector

Filter by Minimum Required Effective Aperture Height, Beam Pitch, and Sensing Range. The tool calculates a fit score and highlights the best-match model for quick decision-making.

DQE model rule: DQE{Beams}/{Pitch}-{EAH}, where EAH = (Beams − 1) × Pitch. By default, Total Height = EAH + 40 mm.

FAQ

1) What safety class does DAIDISIKE DQE meet?

DQE is a Type 4 ESPE. When integrated with a certified safety relay or safety PLC, it supports designs targeting PL e (EN ISO 13849-1) and SIL 3 architectures. Always validate the complete safety function during commissioning.

2) Why does DQE use wired synchronization and what does it improve?

DQE keeps emitter and receiver phase-locked via a sync cable, which suppresses crosstalk, stabilizes timing, and improves immunity to EMI, ambient light and vibration — conditions common on presses, welding cells, and inverter-driven machines. Shielded data/sync leads are standard.

3) Which beam spacing (K) should I choose?

Pick K by the smallest body part to detect: 10 mm (finger), 20 mm (palm), 40 mm (hand/arm), 80/200 mm (body/perimeter). DAIDISIKE DQE supports all five spacings to match your risk assessment and throughput needs.

4) How do I calculate Protective Height (H) and Total Height (L) for ordering?

Use H = (n − 1) × K. Total height follows the product rule L = P + H + J + 24 (P/J depend on K). Example: 32 beams at 20 mm → H = (32−1)×20 = 620 mm; if K=20 mm, L = H + 59 = 679 mm.Tip — Verify the guarded opening and mounting clearances before placing the order.

5) What is the standard detection range? Can DQE reach 6 m?

Factory standard is 0.3–3.5 m. For special projects, DAIDISIKE can engineer solutions within 6 m after application review (background reflections, mounting geometry, stopping time, ambient light).

6) How do I wire the OSSD outputs (NPN/PNP) and enable EDM?

DQE provides dual OSSD channels (A/B) with NPN or PNP selection and NO/NC logic options (A/B/C/D). Wire each OSSD to an independent, certified safety input and enable EDM in the safety relay/PLC to monitor external contactors. Never tie the channels together.

7) How do I determine the minimum safety distance to the hazard?

Apply ISO 13855: S = K × T + C. Here T = machine stopping time + DQE response (≤ 15 ms); select the approach speed K per the protected body part (typ. 1600–2000 mm/s). Confirm with a calibrated stop-time meter and document the result.

8) What makes DAIDISIKE DQE resilient to interference and vibration?

Narrow-band modulated IR, shielded sync/data cables, and a rigid 30×30 mm body deliver high immunity to ambient light (up to 10,000 lux), inverter noise and mechanical vibration/shock (10–55 Hz, 1.5 mm; 100 m/s²).

9) Does DQE support muting and blanking?

Yes. Configure muting/blanking in the safety controller/PLC. DQE’s dual OSSD and EDM keep channel integrity while allowing material flow through conveyors or pallet in-feed.

10) What diagnostics and protections are built into DQE?

Power-on and cyclic self-test, cross-monitoring, short-circuit, overload and reverse-polarity protection. Status LEDs indicate power, blockage and OSSD state; detected faults are latched to prevent unsafe restarts.

11) What are the environmental and mechanical ratings?

IP65 enclosure; operating −10…+40 °C, 35–85 %RH (non-condensing). M12 aviation connectors simplify installation and maintenance in oily, dusty environments.

12) How do I specify the correct DAIDISIKE DQE model when ordering?

Use: DQE | n | K | H | output group | logic. Example: DQE 32 | 20 | 620 | 1 | A → 32 beams, 20 mm spacing, H=620 mm, single output group, PNP-NO logic (standard range 0.3–3.5 m).
