The S125 is a high-pressure version of the S115 linear position sensor designed for underwater marine and offshore applications. It features a larger electronics housing and wet-mate high-pressure connector, allowing continuous submersion up to 3500 m (350 bar / 5000 psi).

The sensor provides a linear output proportional to displacement and is calibrated to a measurement range from 0–5 mm to 0–800 mm, with full EMC protection included.

A rugged 316 stainless steel body and push rod ensure durability and environmental resistance.

Installation options include 316 stainless steel M8 rod eye bearings and body clamps, with free or captive push rod configurations available.

Environmental sealing is rated to IP68 at 350 bar, making it suitable for demanding subsea applications.
