Datasheets

Rectangular inductive proximity sensors for classified areas: from miniature housings of a few millimetres to VariKont 40 × 40 mm and 80 × 80 mm housings with rotatable head, for detecting cams, dampers, actuators and machine parts at distances up to 50 mm.

Key features

  • NAMUR versions (two-wire, EN 60947-5-6) for intrinsically safe circuits, protection levels up to Ga/Da
  • -3G-3D three/four-wire DC versions for zone 2/22 (Ex ec / Ex tc)
  • Sensing ranges from 1.5 to 50 mm, flush or non-flush mounting
  • SIL 2-capable versions
  • Cable, M12 connector, terminal compartment, Faston or stranded wires
