IP69K A-942XS absolute encoder

A/942XS – SSI multiturn absolute encoder · Heavy Duty Ø42 mm · Solid shaft Ø10 mm · 13 bit + 12 bit · IP69K

He ELCIS A/942XS multi-turn absolute encoder It is a heavy-duty industrial encoder designed for applications where reliability, accuracy, and environmental resistance are critical factors. Its construction is entirely in AISI 316L (V4A) stainless steel and its high degree of protection IP68/IP69K They allow their use in environments where humidity, salinity, pressure washing or corrosive agents significantly reduce the lifespan of conventional encoders.

Thanks to its self-powered, magnetic, multi-turn absolute technology, the device maintains its position even after power outages, eliminating the need for batteries or mechanical gear systems. This technology allows for constant monitoring of the shaft's absolute position and the number of accumulated revolutions, reducing maintenance and increasing system availability.

The encoder incorporates an interface SSI with Preset function, exit RS422 and coding Gray, guaranteeing robust and reliable data transmission even in industrial environments with high levels of electrical noise. Its resolution of 13 bits per turn and 12-bit multiturn It provides accurate angular position measurement for automation, positioning, and motion control systems.

The combination of IP68/IP69K protection, stainless steel housing and high mechanical resistance makes the ELCIS A/942XS a particularly suitable solution for marine and naval applications, food machinery subjected to intensive washing, chemical installations, desalination plants, offshore equipment, port cranes, mobile machinery and systems installed outdoors permanently exposed to humidity, salt water, dust or aggressive chemicals.

Unlike standard IP65 or IP67 encoders, this IP69K absolute encoder is designed to withstand high-pressure, high-temperature water jet cleaning processes, offering superior protection against water and contaminant ingress. This feature is especially important in industries where hygiene, reliability, and operational continuity are essential requirements.

Thanks to its resistance to vibrations, mechanical shocks, corrosion, permanent humidity and aggressive environments, the ELCIS A/942XS constitutes a long life cycle solution for demanding industrial applications, where positioning accuracy and mechanical robustness must be maintained even under the most severe environmental conditions.
