AK1 Series - shielded (flush) proximity sensors


AK1 Series - 18 mm Round Metal Shielded (flush)


Great all-around proximity sensors at dynamite prices. 2-wire models work with sinking or sourcing PLC input modules, have very low leakage current.
  • 5mm (std) and 8mm (extd) sensing distances
  • Differential Travel - 2% to 10% (std), 2% to 15% (extd)
  • Repeat Accuracy - 2% (std), 5% (extd)
  • Switch Frequency - 600Hz (std), 300Hz (extd)
  • Time delay to availability (tv) - 3-wire 100ms, 2-wire 50ms
  • LED status indicators are visible 360 around the cylinder
  • 10-30 VDC powered - Complete overload protection
  • IEC IP67 protection rating
  • Metal housing
  • Sink/ source 2-wire or NPN and PNP 3-wire models; Normally open output
  • Axial cable, or M12 quick-disconnect models
  • Data Sheet (389kb)
