About OKW Enclosures
OKW Electronic Enclosure Solutions
OKW Gehäusesysteme GmbH, a 70+ year heritage German manufacturer headquartered near Frankfurt, is the global leader in standard and custom plastic electronic enclosures, extruded aluminum housings and operator interface components for OEM electronics. The company's UK subsidiary (OKW Enclosures Ltd, Fareham, Hampshire) serves European and North American markets; OKW Enclosures USA provides regional support and stock. OKW has established the design standard for off-the-shelf enclosures by combining modular plastic and aluminum geometries with custom-finishing services enabling rapid product development cycles.
The plastic enclosure range spans from micro (12×12×15 mm handheld units) through desktop instruments (360×240×160 mm), engineered in polycarbonate and polyamide to IP54–IP67 sealing grades depending on mounting configuration. Mounting variants include handheld recessed-grip cases, wall-mount backplate designs, flush-mount DIN-rail enclosures, desktop table-top units and instrument-panel rack-mount styles. Material selection (polycarbonate clarity, polyamide mechanical strength, UV-stabilized colors) accommodates diverse industrial, laboratory and consumer-equipment applications.
Extruded aluminum enclosures (100×100×40 mm to 282×170×50 mm) provide superior thermal management for power electronics, RF shielding enclosures (die-cast aluminum with conductive coatings for EMI/RFI suppression) and environmental durability in harsh industrial and marine settings. All aluminum options support stainless-steel hardware, powder-coat finishes and integrated cable grommets.
Custom-finishing services address the complete electronics housing ecosystem: silk-screen printing with logos, serial numbers and instructional graphics; membrane keyboards with integrated switches and backlighting; potentiometer knobs (molded plastic and anodized aluminum, 10–50 mm diameter); internal PCB standoffs, cable-entry grommets, battery compartments and internal shielding films for RFI/EMI mitigation. These complementary services reduce assembly time and allow designers to source a complete electromechanical housing solution from a single vendor.
ChatMRO simplifies OKW enclosure selection by letting you specify size envelope, mounting style, material requirement (plastic for light-duty electronics vs. aluminum for thermal/EMI management), sealing grade (IP rating) and any custom-finishing needs, and instantly matching available standard and semi-custom enclosure options with technical specifications, lead times and pricing — accelerating product design cycles and reducing tool-up costs.

Frequently asked questions
What's the difference between polycarbonate and polyamide enclosures, and when should I choose each?
Polycarbonate offers superior optical clarity, better UV stability (for sunlight-exposed applications) and higher impact resistance; polyamide provides better mechanical strength under sustained load, better chemical resistance and lower material cost. Choose polycarbonate for consumer electronics, test instruments or applications where optical clarity matters (display cutouts, LED indicators); choose polyamide for industrial control panels or harsh-chemical environments.
What does IP rating mean on an OKW enclosure, and how does mounting style affect sealing?
IP rating (Ingress Protection) quantifies dust and liquid resistance: IP54 allows small dust ingress and splash resistance; IP65 is dust-tight with low-pressure jet resistance; IP67 survives temporary submersion up to 1 meter. Mounting style affects sealing: desktop enclosures naturally achieve higher IP ratings than flush-mount or wall-mount designs due to fewer openings; specify your environmental exposure (dust, spray, submersion) to ensure the right combination of enclosure style and IP rating.
Does OKW offer custom internal PCB standoffs, cable-entry grommets and shielding components, or do I need to source those separately?
Yes — OKW's custom-finishing services include internal PCB standoff placement, cable-entry grommets (standard or sealed M20/M25 grommet kits), internal shielding films for EMI/RFI mitigation and battery compartment inserts. These integrated services reduce assembly labor and ensure compatibility; ordering the complete housing system from OKW rather than sourcing enclosure + components separately saves cost and accelerates time-to-market.
Can OKW enclosures be modified for sealed potentiometer knobs, push-buttons or indicator lights, and what's the lead time for custom configurations?
Yes — OKW offers integrated potentiometer knob mounts, sealed push-button cavities and LED indicator light cutouts as part of the custom-finishing process. Standard lead times for custom silk-screen, button cavities and knob integration are 4–6 weeks; larger design modifications or new tooling requests may require 8–12 weeks. Prototyping runs are available through OKW's engineering team for faster validation.
What EMI/RFI shielding options are available on OKW aluminum enclosures, and how effective are they?
OKW die-cast aluminum enclosures can be finished with conductive epoxy or nickel-plated shielding films achieving 60–80 dB EMI attenuation in the 1 MHz–1 GHz range (typical for consumer/industrial RF immunity). Internal shielding compartments separate analog and digital circuits, reducing crosstalk. Shielding effectiveness depends on seams, cable-entry quality and grounding continuity; consult OKW's application engineering for high-EMC environments (medical devices, RF instrumentation) requiring certified shielding levels.
