In today’s industrial world, reliable communication is critical. When long distances, electrically noisy environments, and cost pressures meet, RS485 remains one of the most trusted solutions
Why RS485?
RS485 offers robust, differential signaling that ensures stable communication even in harsh electrical conditions. With cable lengths up to 1,200 meters, it is ideal for large-scale installations such as pumping stations, solar farms, or distributed automation systems. Thanks to its multi-drop capability, up to 32 devices can share a single bus, minimizing cabling and reducing hardware costs.
For customers, this means dependable data transmission, excellent price-performance, and easy integration with widely available PLCs.
At POSITAL, our strength lies in deep technical know-how and flexibility. Over the years, we have successfully integrated multiple protocols over RS485, ensuring smooth implementation in a wide range of customer applications. Thanks to our mass customization approach, we can deliver encoders with exactly the right specifications for each project. RS485 encoders are available in a broad variety of mechanical configurations — including cable or connector options, synchro clamping, and blind hollow shaft designs — allowing customers to select the perfect fit for their installation requirements.
Applications Across Industries
The adaptability of RS485 encoders makes them a strong fit for diverse industries:
Water & Wastewater: Reliable monitoring and control of gates, pumps, and actuators
