Ensuring Signal Integrity for Precision Farming

In digital agriculture, the precise transmission of sensor data is essential for GPS control systems and automated application systems. ALDERS supplies high-resolution encoders and Hall-effect sensors for this purpose; these operate without wear and are resistant to electromagnetic interference (EMI). These components guarantee noise-free, linear signal processing—indispensable for millimeter-accurate guidance or variable-rate control of seeds and fertilizer. Thanks to their robust design, this precision is fully maintained even amidst the heavy vibrations encountered when driving over uneven fields.

Hygienic Design and Protection Against Aggressive Media

Agricultural machinery requires intensive cleaning after use to prevent corrosion caused by organic residues and chemicals. To address this, we offer self-sealing screws, nuts, and specialized sealing boots from APM HEXSEAL. These components hermetically seal control panels and housing feed-throughs, meeting the IP69K protection rating. The high-performance elastomers used are resistant to acids, alkalis, and UV radiation, ensuring that the internal contacts of switches and pushbuttons remain permanently protected against corrosion—even with frequent use of high-pressure cleaners.

Ergonomic Human-Machine Interfaces (HMI) for Continuous Operation

Controlling complex machinery requires intuitive HMI systems that reduce physical and cognitive strain on the operator. ALDERS supplies customizable multifunction grips—such as the AG2006—and joysticks from OTTO Controls. These control elements enable the operation of numerous functions without the need for visual confirmation, thanks to clear haptic feedback. Acting as an extended workbench, we handle the entire pre-assembly process: this includes integrating specific thumbwheels and push-buttons, custom cable assembly, and protective potting of the electronics to shield them from vibration, thereby ensuring maximum reliability during demanding harvesting operations.

Durability under extreme mechanical stress

In agricultural machinery, standard components often fail due to material fatigue caused by constant vibration. ALDERS therefore relies on heavy-duty toggle and rocker switches from NKK Switches and OTTO Controls, which are rated for millions of switching cycles. Their reinforced mechanical design and high-quality contact alloys prevent arcing and material breakage. This ensures the machinery remains operational throughout its entire service life and significantly reduces the need for costly field repairs during critical harvest periods.
