SGM-PF10 is a magnetostrictive position sensor with a flat disc head for hydraulic cylinders where there is little room behind the end cap. It is rated 35 MPa continuous (70 MPa peak), measures 25–8000 mm, is sealed to IP68 and outputs analog, SSI or RS485.
The flat structure design is suitable for U-shaped and other limited-space hydraulic cylinders. Measuring range 25-8000mm, Analog/SSI/RS485 output, 35MPa(continuous) 70MPa(peak). Part number prefix SGM stands for the SEGMENsensor magnetostrictive range; the full ordering code is explained below and in the datasheet.
