Replacing an installed magnetostrictive position or level sensor starts with its specification, not its brand. Send us the stroke, mounting, output, connector and pressure rating of the sensor you have; we match them to an SGM or SE part number from our datasheets and tell you what matches and what differs before you order.
Replacing an installed magnetostrictive position or level sensor starts with its specification, not its brand. SEGMENsensor matches the stroke, mounting, output, connector and pressure rating of the installed sensor to an SGM or SE part number from its datasheets, and states what matches and what differs before you order.
Values in the right-hand column are taken from the SGM / SE series datasheets. Parameters not listed there are not claimed; ask us and we will answer per series.

| Analog output | Signal type and direction (rising / falling) | 4–20 mA, 0–20 mA, 0–10 V; 0–5 V (SGM-PR20); 0.5–4.5 V / 0–5 V / 4–20 mA (SE-PR30); 16-bit D/A |
| Digital output | Interface and settings (SSI word length, Gray/binary, resolution; Modbus address) | RS485 Modbus RTU (all SGM series); SSI on SGM-PR10 / SGM-PE10, on request on SGM-PR20 / SGM-PF10, set in the ordering code (e.g. SS25G005F); Profinet on request (SGM-PR10 / PE10) |
| Non-linearity / repeatability | Values the application actually needs | <±0.01% FS (min ±50 µm) / <±0.001% FS (min ±5 µm) on SGM-PR10, PE10, PR20, PF10; repeatability ±0.005 mm on SGM-PF20, PR40, PR50, LS10, LK10 |
| Pressure rating | Cylinder operating and peak pressure | 35 MPa continuous, 70 MPa peak (SGM-PR10 rod); 35 MPa (SGM-PF10, SGM-PR40, SGM-PR50) |
| Mounting and connector | Thread, flange, connector type and pin assignment | SGM-PR10: M18×1.5 or custom-made; M16 connector (analog / RS485 6-pin, SSI 7-pin) or cable. Other series: see the series datasheet |
| Supply and temperature | Supply voltage, ambient and process temperature | 24 V DC ±20% standard, 12 V and 5 V ranges depending on output and model (SE-PR30: 12 or 24 V); -40 to +85 °C; SE-LX rod -40 to +250 ℃ in the high-temperature version |
| Protection and hazardous area | IP class; zone and Ex marking if used in a hazardous area | IP67 (SGM-PR10, PE10, PE20), IP68 (SGM-PR20, PF10, PF20, PR40, PR50, LS10); SE-PR30 intrinsically safe; SE-LX10/20/30 flameproof |
| Magnet or float | Ring magnet, slider or float type and size | Matched ring magnets, sliders and floats supplied per series |
| Samples | — | 1–5 pcs, 5–7 working days |
| Lead time | — | Samples 1–5 pcs in 5–7 days; production lead time confirmed with the quotation |
Pick the series by how the installed sensor is mounted, then check range, output and pressure on the series page.
A replacement is confirmed on paper and on a sample before production — never assumed from a headline specification.
