Perimeter Access Guarding Device

Long range, multi-beam presence sensing device for guarding robot centers and large machines.  Ideally suited to detect the torsos of personnel entering a hazardous area.

  • 1 to 6 beams available
  • Protective Heights from 231 mm to 1731 mm (9.12 to 68.17 in.)
  • Operating range of 70 m (229 ft.)
  • Compact size — 46 x 55 mm (1.81 x 2.17 in.)
  • Simple “two-box” design — no separate control box required
  • Individual Beam Indicators
  • LED status indicators and numeric displays
  • Explosion Proof enclosure available


Installation and alignment is simplified with Individual Beam Indicators, which glow red when the beam is out of alignment or blocked. The separate Scan Codes allow the installer to select unique scan frequencies that eliminate cross-talk with adjacent PA4600 systems. Diagnostics are greatly enhanced with the LED status indicators and numeric displays.


The cost effective Perimeter Access Guarding Device PA4600 provides guarding of robot centers and large automated machinery. The corner mirrors direct the infrared beams to four sides of a machine.
