Food-processing agricultural machines, such as seed cleaners, graders, sorters, vegetable washers, fruit processors, and silage harvesters, demand wiring systems that combine high performance, hygienic standards, and mechanical reliability. The wire harness is the backbone of these machines, connecting sensors, motors, actuators, lighting, user interfaces, and safety devices while ensuring seamless power and signal distribution in environments where moisture, dust, and food residues are constant challenges.
Materials & Components
OEM S.r.l. develops and produces harnesses specifically tailored for food-processing agricultural machines, using components selected for both electrical performance and compliance with hygiene and safety standards:
- Cables with food-grade compliant insulation, resistant to cleaning agents, high humidity, and thermal stress (PVC, XLPE, silicone, halogen-free).
- Connectors with IP67/IP69K protection levels, suitable for washdown environments and resistant to detergents and disinfectants.
- Protective elements such as corrugated conduits, smooth tubing, and heat-shrink sleeves designed for easy cleaning and resistance to bacterial build-up.
- Stainless steel or polymer mounting accessories ensuring corrosion resistance in wet environments.
- Specialized sensors and interfaces, including temperature probes, load cells, and control switches, integrated seamlessly into the harness design.
Manufacturing Procedures & Techniques
Our production process combines advanced automation with precise manual assembly to guarantee reliability in demanding environments:
- Automated cutting, stripping, and marking for precision and traceability.
- Crimping and sealing of terminals, verified through pull-force testing and cross-section micrographs.
- Overmolding and potting techniques to achieve hermetically sealed connections.
- Shielded cabling for signal lines to ensure electromagnetic compatibility in machines operating with multiple electronic subsystems.
- Customized ergonomic routing to enable easy installation, cleaning, and maintenance while minimizing downtime.
Harnesses for food-processing agricultural machines can be configured for:
- Motor and drive control circuits for washing, cutting, or processing units.
- Sensor integration (temperature, weight, pressure, optical sensors).
- Lighting and signaling systems inside machines or processing lines.
- Control panels and operator interfaces with waterproof connectors.
- Safety systems (emergency stop circuits, guards, interlocks).
