Omron F3SJ Compatible Mounts

Notes for legacy replacements. This guide helps engineers swap the Omron F3SJ with DAIDISIKE DQC safety light curtains while preserving existing mounts. We cover mechanical fit, common brackets, and the adapter kits you'll need.

Important: Ensure the replacement meets all safety standards, including recalculating safety distance S = K×T + C. Mounting height and orientation affect field performance.

1) Legacy mount compatibility

While the Omron F3SJ mount profiles and bracket kits are not directly interchangeable with DAIDISIKE’s DQC series, you can use common adapter kits and brackets for smooth replacements. The following guide outlines compatible mounting systems and adjustments.

2) Mechanical fit & adjustments

When switching from Omron F3SJ to DAIDISIKE DQC, it's essential to address physical fitments such as mounting brackets, clearance adjustments, and protective height (PH). Below are recommended installation steps for compatibility:

Bracket & Adapter Kits

  • L-brackets: Compatible for DQC standard (30×30), quick installation in existing F3SJ mounts.
  • T-slot sliders: For rear mounting on DQC slim (30×17.5), check depth clearance.
  • Mid-support: For PH > 1000 mm, ensure added stability.

Mounting Alignment

  • Angle check: Ensure optimal tilt angles for optical alignment (±3° tolerance).
  • Mid-support addition: Add for high PH or heavy-duty environments.
  • Torque limits: Tighten all fixtures to prevent shifting during operation.

3) Accessories compatibility

If you’re reusing existing accessories (covers, cables, or alignment lasers) from the Omron F3SJ, ensure the following swaps for proper fitment:

Mounting accessories

  • L-bracket replacements for direct mounting on DQC
  • Mid-support adaptors to avoid vibration and misalignment

Sensor alignment tools

  • Laser pointer alignment for precise sensor setup
  • Target card compatibility for both F3SJ and DQC models

Protection covers

  • Omron F3SJ covers will not directly fit; opt for DQC-compatible protection covers
  • Oil-mist and welding spatter covers are available for DQC model protection

4) Final checks & commissioning

After physical installation and wiring, ensure all connections are secure, and validate the system with operational tests.

  • Verify mounting height and tilt; cross-check PH to avoid misalignment.
  • Recalculate safety distance S = K×T + C with real-time tests.
  • Ensure appropriate wiring from F3SJ to DQC; use the wiring cross-reference chart.
  • Commission system with test rods (10/30/40 mm) per application requirements.
