SEGMENsensor manufactures M8, M12, M18, M30 cylindrical and square inductive proximity sensors — NPN/PNP, shielded/unshielded, weld-immune variants. IP67 standard, custom output and housing, OEM from 10 pcs.
An inductive proximity sensor detects metallic objects without physical contact, using an oscillating electromagnetic field. When a conductive target enters the sensing range, eddy currents dampen the oscillator — triggering the output. SEGMENsensor manufactures the SE2 series: cylindrical M8/M12/M18/M30 and square housing sensors in NPN/PNP, NO/NC, 2-wire/3-wire configurations. Standard sensing distances from 1 mm (M8) to 25 mm (M30). IP67 rated, CE and RoHS certified. Suitable for general automation, automotive welding, semiconductor handling, and all-metal detection in harsh environments. OEM custom from 10 pcs, 2–3 week lead time.
Full range from M8 compact to M30 long-range. All sizes available in NPN or PNP, Normally Open or Normally Closed, shielded or unshielded flush-mount.
SE2 series standard specifications. All models available in NPN or PNP, NO or NC. Long-range (LR), high-temp (HT), and all-metal (AM) variants on request.

Match the right SE2 variant to your operating environment. Three protection tiers — standard, high-temperature, and all-metal detection.
Three stages: field generation → target detection → output switching. Entirely solid-state, no moving parts, rated for 100+ million operations.
From semiconductor automation to automotive welding — SEGMENsensor proximity sensors are specified for the harshest industrial environments.
SEGMENsensor is a direct factory — not a trading company. Our Shenzhen manufacturing facility produces inductive proximity sensors in M8, M12, M18, M30, and square housing formats. We supply OEM equipment builders, integrators, and distributors in 30+ countries, with full CE and RoHS documentation and optional private-label packaging.
Every size available in NPN-NO, NPN-NC, PNP-NO, PNP-NC. 2-wire AC/DC variants also available. No tooling required to switch output type.
Standard 2 m PVC cable or M12 4-pin plug. Custom cable length (0.5 m–10 m), PUR/PTFE insulation, straight or right-angle M12 connector available from 10 pcs.
CE Declaration of Conformity per EN 60947-5-2 included with every shipment. RoHS 3 compliance certificate available. ISO 9001:2015 factory audit report on request.
Standard SE2 configurations ship in 2–3 weeks from 10 pcs. Private-label OEM packaging (custom box, label) requires 50 pcs, 4–6 weeks. Sample 1–2 pcs accepted.
Identical EN 60947-5-2 compliance and IP67 rating — at 40–60% lower landed cost, with direct factory support and sub-3-week lead times.
