Official product documentation for SEGMENsensor inductive proximity sensors. SGI-GP, SGI-FM and SGC-GP cylindrical sensors with NPN/PNP output, flush and non-flush models. Additional series datasheets in preparation.
The SEGMENsensor proximity downloads page provides the inductive proximity sensor datasheet as a PDF for the SGI-GP, SGI-FM and SGC-GP families: 6.5 mm, M8, M12, M18 and M30 cylindrical sensors in flush and non-flush versions with NPN or PNP, NO or NC outputs. It lists sensing distances, outputs, supply voltages, connections, housing materials and ordering codes.
Standard 6.5 mm / M8 / M12 / M18 / M30 cylindrical inductive proximity sensors for metal detection in automation, conveyor, and machine tool applications. Shielded (flush) and unshielded (non-flush) mounting options. NPN/PNP normally-open and normally-closed outputs, plus DC 2-wire, AC and AC/DC versions; 4,060 checked part numbers.
Each table row also has a PDF button that creates a one-page datasheet for that part number.
SEGMENsensor also manufactures capacitive proximity sensors for non-metallic material detection, photoelectric sensors for long-range detection and color-mark sensing, and Hall effect sensors for magnetic field detection. English datasheets for these series are currently in preparation.
Datasheets in preparation. English-language datasheets for capacitive, photoelectric, Hall effect, and reed switch sensors are being finalized. Contact us at info@segmensensor.com to request a specification sheet for a specific model.

Inductive proximity sensors detect ferrous and non-ferrous metal targets without physical contact, delivering reliable switching in harsh industrial environments. The following applications are the most common scenarios documented in SEGMENsensor technical literature.
Conveyor and Assembly Line Object Detection: M18 and M30 inductive proximity sensors detect metal components on conveyor belts for part counting, jam detection, and positioning in automotive and electronics assembly. PNP output connects directly to PLC sourcing input modules for straightforward wiring.
Machine Tool End-of-Travel and Home Position: Flush-mount M12 sensors embedded in machine tool slides detect axis end-of-travel positions; housing material and protection rating for the coolant spray and metal chips common in CNC machining centres are selected per part number.
Welding Robot Position Feedback: SGI-WR weld-field immune inductive proximity sensors (immune to constant and alternating magnetic fields up to 150 mT) detect fixture clamp positions inside robotic welding cells. Weld-immune ratings prevent false triggering from high-current magnetic fields generated during MIG and resistance welding operations.
