AT1 Series - unshielded (non-flush) proximity sensors


AT1 Series - 30 mm Round Metal unshielded (non-flush)


For applications requiring more sensing distance at a reasonable price. 2-wire models work with sinking or sourcing PLC input modules, have very low leakage current.
  • 15mm (std.) and 20mm (extd.) sensing distances
  • Differential Travel - 2% to 10% (std), 2% to 15% (extd)
  • Repeat Accuracy - 3-wire 2% (std), 2-wire 5% (std), 5% (extd)
  • Switch Frequency - 3-wire 200Hz (std), 2-wire 150Hz (std), 150Hz (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 (398kb)
