Typical Applications
Presses / shears / press brakes: 10–20 mm for hand protection with quick stop via relay/PLC.
Large fixtures, conveyors & robot cells: 40–80 mm for presence/perimeter detection with interlocked doors.
General machinery: pair with safety relay/PLC for stop, restart interlock and EDM monitoring.
Safety distance reference (ISO 13855): S = K × T + C, where T is total machine stopping time.
Frequently Asked Questions
What resolution should I choose on the DQV for finger, hand or body protection?
Choose by the smallest body part that can reach the hazard. Use 10 mm for finger protection at close-in assembly, 20 mm for palm/hand protection at packaging and access openings, and 40 or 80 mm for hand-arm or body presence and perimeter zones. The DQV offers 10/20/40/80 mm, so one series covers presses, conveyors and aisle guarding.
Is the DQV a Type 4 safety light curtain and can it reach PL e?
The DQV is built to the IEC 61496-1/-2 architecture with dual-channel safe outputs and self-diagnosis. The Performance Level (up to PL e / Cat. 4 under ISO 13849-1) is achieved by the complete safety function — the curtain and controller plus a certified safety relay or safety PLC with EDM feedback validated by the integrator.
Can the DQV replace an Omron F3SG-SR, SICK deTec or Keyence safety light curtain?
In many cases yes. The DQV matches common 10/20/40 mm resolutions, 0.3–3 m standard range and dual-channel safe outputs through its controller, so it fits the same safety loop. Confirm protective height, resolution and controller output type (relay or transistor) against the unit being replaced; see our Keyence/SICK alternatives buyer's guide.
How do I wire the DQV safe outputs to a PLC or safety relay with EDM?
The DQV delivers its safe outputs through external or inner W/N/S/P controllers as dual relay or dual transistor channels. Route the two channels into a dual-channel safety relay or safety PLC input, and run the EDM/feedback loop through forcibly-guided contacts so a welded contact is caught on restart. See our OSSD NPN/PNP wiring with EDM guide.
How do I calculate the minimum safety distance for the DQV?
Apply ISO 13855: S = K × T + C, where K = 2000 mm/s (hand-speed constant), T is the total machine stop time plus the curtain response (≤10 ms), and C is the intrusion factor from the resolution. The faster ≤10 ms response lets you mount closer to the hazard. Our ISO 13855 calculator computes the exact distance.
What ingress protection and response time does the DQV have?
The DQV is rated IP65 (dust-tight, water-jet resistant) with a stainless threaded M12/aviation connector head, a typical response time of ≤10 ms, and ambient-light immunity of ≥10,000 Lux with anti-flicker filtering against weld arc and ambient light — suitable for most indoor stamping, automation and packaging environments.
