Performance highlights S125 (Submersible) linear inductive position sensor
The S125 sensor delivers highly accurate linear position feedback using non-contacting inductive technology, eliminating mechanical wear for longer service life. Its robust stainless steel body ensures exceptional performance in subsea and harsh environments up to 350 bar pressure.
Usage conditions
Ideal for underwater applications including ROVs and marine machinery, the S125 performs in temperature ranges of -4°C to +50°C and resists vibration, shock, and electromagnetic interference.
Possible applications
- Subsea robotics (e.g., ROVs)
- Offshore oil & gas installations
- Marine hydraulics and actuators
- Underwater inspection tools
- Scientific measurement equipment
Advantages of choosing this product
The S125 offers a space-efficient, rugged solution with configurable stroke lengths and signal outputs. It simplifies integration through axial or radial wet-mate connectors, supports spring-loaded push rod options, and operates maintenance-free due to its wear-free core technology.
Other important features
- EMC-compliant (EN 61000-6-2, EN 61000-6-3)
- Frequency response >10kHz (voltage), >300Hz (current)
- Shock resistance up to 40g
- Vibration rated at 10g
- Available with M8 or M12 rod-eye fittings
- Up to 3500m operating depth
