Substrate Thickness and Edge Geometry Tolerances
Knuffi Edge Protection Profile Type O is engineered to interface directly with thin structural edges, sheet metal fabrications, and flat rigid panels. The integrated channel slot is dimensioned specifically to engage substrate thicknesses ranging from 1 mm to 2 mm (0.039 in to 0.079 in). With an insertion depth of 10 mm (0.39 in), the profile provides a secure friction fit over the perimeter of exposed metalwork without requiring pre-drilling or separate mechanical fasteners.
Due to the flexible nature of its molded polyurethane body, Type O conforms efficiently to diverse structural shapes. It is fully compatible with straight linear runs, curved panels, radiused corners, and contoured edge transitions commonly found on industrial equipment.
| Interface Parameter | Specification / Operational Limit |
|---|---|
| Compatible Edge Thickness | 1.0 mm to 2.0 mm (0.039 in to 0.079 in) |
| Slot Insertion Depth | 10 mm (0.39 in) |
| Overall Profile Dimensions | 20 mm (W) x 20 mm (H) (0.79 in x 0.79 in) |
| Linear Weight | Approx. 0.27 kg/m (0.6 lbs per 1-metre unit) |
| Standard Supply Formats | 1-metre pre-cut sections, 5-metre continuous rolls |
| Thermal Operating Range | -40 °C to +100 °C (-40 °F to +212 °F) |
Industrial Machinery and Plant Equipment Interfaces
Knuffi Type O profile bumpers are designed for integration across logistics facilities, production cells, and automated machinery lines. Standard substrate interfaces include:
- Sheet Metal Guarding: Protects personnel from contact with raw edges on machine enclosures, safety doors, and electrical cabinet entries.
- Structural Steel Flanges: Shields thin metal flanges, structural trim, and thin-gauge channel edges.
- Chassis Panels: Provides impact-absorbing edge borders on mobile automation, AGVs, carts, and industrial transport chassis.
- Perforated Cable Trays: Prevents wire insulation abrasion and personnel lacerations along the exposed sidewalls of routing trays.
Dimensional Limits and Incompatible Configurations
Type O must be matched strictly to edge thicknesses within the 1 mm to 2 mm operating window. Forcing the profile over substrates thicker than 2 mm will lead to over-stretching, permanent structural deformation, or splitting of the polyurethane slot. For non-linear installations requiring custom segments, the profile is field-trimmable to exact dimensions using a standard utility knife.
Environmental and Regulatory Conformance
The profile maintains physical stability in operating environments ranging from -40 °C to +100 °C (-40 °F to +212 °F). Its 100% CFC-free, silicone-free polyurethane formulation with co-extruded UV-stabilized and moisture-resistant film ensures compatibility with outdoor installations and washdown environments utilizing mild industrial detergents. Fire behavior complies with DIN 4102 B2 and UL 94 HB, while safety marking layouts align with ASR A1.3 and ISO 7010 visual awareness standards.
