Typical Applications
Presses / shears / press brakes: 10–20 mm resolutions suit hand protection; fast response enables shorter safety distance.
Packaging / logistics: 40 mm for aisle 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.
Frequently Asked Questions
Is the DQB a Type 4 / PL e safety light curtain?
The DQB is designed to the IEC 61496-1/-2 Type 4 architecture, with self-monitoring, cross-monitoring and EDM. It is suitable for EN ISO 13849-1 PL e safety chains when integrated with a certified safety relay or safety PLC. The final PL/SIL of the complete safety function must be validated by the integrator per ISO 13855.
Which resolution should I pick for finger protection?
Choose the 10 mm resolution for finger protection at assembly fixtures and close-to-hazard stations. Use 20 mm for palm protection on packaging and access openings, and 40 mm for hand, arm or body presence in aisles and zone guarding. Protective height follows H = (n − 1) × K, where K is the resolution.
How do I wire the OSSD outputs with EDM, and does it support NPN and PNP?
The DQB provides dual-channel safety outputs (OSSD) selectable as NPN or PNP, NO/NC, with sink current up to 500 mA and short-circuit protection. Wire both OSSD channels into independent dual inputs on a certified safety relay or PLC and connect EDM (external device monitoring) feedback so the system verifies the contactors before each restart.
Can the DQB replace an Omron, Keyence or SICK safety light curtain?
In many cases yes. The DQB shares the common through-beam infrared design, Type 4 architecture, dual-channel NPN/PNP OSSD outputs, EDM and M12 connectors, so it fits similar brackets and safety-relay wiring. Match the resolution (10/20/40 mm), protective height and sensing range (0.3–3 m standard) to the unit being replaced and verify the safety distance per ISO 13855.
What is the response time, sensing range and ingress protection?
The DQB has a response time of ≤15 ms, a standard sensing range of 0.3–3 m (0.3–6 m optional), and an IP65 enclosure that is dust-tight and water-jet resistant. Ambient light immunity is ≥10,000 Lux at incidence ≥5°. The fast response helps achieve a shorter ISO 13855 safety distance S = K × T + C.
