Performance highlights S508 Submersible rotary sensor
The S508 is a high-resolution submersible rotary sensor engineered for harsh industrial, marine, vehicle, and offshore applications. It delivers precise angular feedback using Althen’s non-contact inductive technology. With excellent linearity (≤ ±0.25% FSO) and virtually infinite resolution, this sensor ensures reliable, repeatable measurements over long service life—even under extreme conditions.
Usage conditions
Encased in 316 stainless steel and sealed to both IP68 (10 Bar) and IP69K standards, the S508 is designed for rugged environments with full EMC protection. It operates reliably between -40°C to +125°C and is vibration and shock resistant (IEC 68-2-6 and 68-2-29).
Possible applications
- Hydraulic or submersible valve monitoring
- Offshore drilling equipment
- Steering and rudder angle detection (marine)
- Tilt or rotation measurement in mobile machinery
- Industrial robotics and automation arms
Advantages of choosing this rotary position sensor
The S508 offers cost-effective durability, outstanding stability across temperature ranges, and exceptional customization. Customers can specify the measurement range (up to 160°), signal output, and cable length. With compact dimensions and flexible mounting options, it integrates seamlessly into OEM systems and test benches.
