  • Scanning angle(Detection area) is increased to 180°.
  • PBS-03JN works by scanning an LED of wavelength lambda = 880nm and the coordinates are calculated by measuring distance to object and its step angle. Obstacle is then detected in the setting area
  • Detection area can be set by PC(RS-232C).
  • Detection distance with 3 steps output for each area can be set.
  • Changeover for Max. 15 kinds of detection area set by PC can be made by outer bit input.

Hokuyo PBS-03JN Specifications

Infra-red LED
Detectable object and detection area
White paper with 300×300mm(Placed in parallel with sensor projection surface), 0.2 to 3m×2m(Origin point is scanning center position) but within scanning angle 180°
Area setting
Output 1
Output 2,3
Linear setting to progressive direction, fan-shaped setting to optical axis direction,
Percentage(%) setting against output 1 pointer
2 scanning mode

When each detecting area setting, it sets individually for each output.
10% or less of detection distance(it is not getting 60mm or less)

Output Photo-coupler/NPN open-collector output(30VDC 50mA or less)
Output 1,2,3 : output OFF when detecting within area, trouble output : output ON when normal operation*
Input(Input 1 to 4) Photo-coupler input(Anode common, each input current 4mA or more), This can changes setting detection area.
Detecting area setting It set the area No. by Input 1, 2, 3 and 4
It stops the emission by getting all Input 1, 2, 3 and 4 to ON(OFF : H level input, ON : L level input)
