Product Highlights
  • Optical sync between emitter/receiver — fewer cables, quick commissioning.
  • Robust against interference: filtering and EMC design attenuate flicker, welding glare and ambient sources.
  • ≤15 ms response accelerates stop distance calculations (ISO 13855) while maintaining protection.
  • ≥10,000 Lux immunity; status LEDs for power/blocked states ease troubleshooting.
  • Slim 25×23 mm body; M12 / aviation connectors available.
  • Meets IEC 61496-1/-2 concepts when combined with a certified safety relay/PLC.

Values consolidated from provided MK manual shots; in case of discrepancy, shipped datasheet and certificates prevail.

Resolution & Application Guide
Resolution (K)Typical Application
10 mm / 14 mmFinger protection (assembly, fixtures, close-to-hazard stations)
20 mmPalm protection (packaging, access openings)
40 mmHand/arm or body presence (aisles, zone guarding)

Protective height H = (n − 1) × K. Overall length L = P + H + J + 20 (10 mm allowance at each end). P/J depend on resolution; see spec tabs.

Use distance option code A (0.3–3 m) or B (0.3–6 m) when ordering. Keep the model format MK-K-NN-H.

Typical Applications

  • Presses / shears / press brakes: 10–20 mm resolutions suit hand protection; fast response enables shorter safety distance.
  • Assembly fixtures & robot periphery: finger/palm detection with interlocked safety loop; easy maintenance.
  • Packaging / logistics: 40 mm and above 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.
