Omron installation components form the backbone of panel assembly across automation, HVAC, and machinery control. They include DIN-rail mounting hardware, junction boxes, wiring ducts, and auxiliary fittings that ensure stable mechanical fixation, correct protection class, and easy maintenance access. For procurement engineers, this category directly affects reliability, safety approvals, and installation time — three factors that define lifetime cost more than the component price itself.
Omron mounting systems are based on EN 60715 rail geometry, supporting both miniature and industrial modules.
Typical dimensions: 35 × 7.5 mm and 35 × 15 mm profiles, with steel (zinc-plated) or aluminum material options.
In multi-device enclosures, Omron rails maintain alignment under continuous thermal cycling (–25…+70 °C) — a frequent weak point in cheaper rails that deform around screw holes.
Omron junction boxes protect wiring nodes from dust and moisture according to IEC 60529 (IP 54 – IP 66).
Materials include ABS, polycarbonate, or stainless steel 304, chosen by environment:
Environment | Preferred Material | Reason |
| Indoor control cabinet | ABS | Light, cost-effective |
| Outdoor / UV exposure | Polycarbonate | UV-stable, impact resistant |
| Hygienic / chemical areas | Stainless 304 | High temperature & detergent tolerance |
All variants are CE/EAC certified and support wall, base-plate, or rail mounting.
Cable entries: M16–M32 glands or soft-membrane seals; grounding stud integrated on metallic housings.
The brand’s wiring ducts, trunkings, and accessories are manufactured from halogen-free PVC or PA 66, compliant with UL 94 V-0 flammability.
Slot width options (4–8 mm) suit both fine-strand and solid conductors.
Color coding in standard grey (control) and blue (24 V DC) aids circuit identification.
Features worth noting:
Fasteners, terminal markers, and grounding kits complete the installation lineup.
Screws and spacers use zinc-nickel plating (≥ 120 h salt-spray) to resist corrosion in humid factories.
Standardized thread sizes (M3/M4) simplify tooling.
Omron also provides identification strips and labels matching 5.5 mm duct slots — compatible with universal thermal printers.
Parameter | Plastic (ABS/PC) | Metal (Steel/Al) |
| Weight | Low | High |
| Rigidity | Moderate | Excellent |
| EMC Shielding | Limited | Full |
| Corrosion Resistance | Excellent indoors | Requires coating |
| Temperature Range | –25…+70 °C | –40…+120 °C |
Plastic dominates in indoor automation panels; metal remains essential for high-EMI or mechanical-stress zones. In mixed environments, engineers often specify aluminum rails with plastic boxes — achieving light weight while keeping thermal stability.

Frequent mistakes:
Omron installation accessories interconnect seamlessly with Omron relays, power supplies, PLC modules, and with third-party devices from Eaton, Schneider Electric, Phoenix Contact, and Weidmüller.
All rails and ducts follow EN 60715 and EN 61326 EMC guidelines, ensuring predictable fit and low noise coupling between signal and power wiring.
When upgrading legacy panels, Omron’s ducts can replace older European formats without modifying mounting hole centers — a small but crucial benefit during retrofits.
Compact ABS housings (IP 65) with captive screws and PE studs. Suitable for terminal and sensor junctions. Internal DIN rail included by default.
Precision-rolled 35 mm profiles, galvanized or anodized, compatible with miniature contactors and relay sockets. High torsional rigidity up to 800 N mm.
Halogen-free PVC ducts, slot pitch 5 mm, cover with locking ridge. Designed for automated cutting machines — reduces waste and improves repeatability.
Screw, nut, and spacer sets for multi-tier assemblies. Nickel-plated finish extends service life in humid zones.
