Hokuyo Area Configuration/PBS-03JN Scanning Rangefinder

Infra-red LED light source, distance measurement type obstacle detector. Fine settings available for each pattern, greatly improved than normal reflective photo sensors. Scanning angle: 180°, compact body with height of 60mm.
  • PBS-03JN
  • Hokuyo


-> It is 60% smaller than PB9 in volume. Scanning angle(Detection field) is increased to 180° and detection dead zone got smaller.
-> Operation principle: The detection field is scanned by LED (lambda = 880nm), objects coordinates are calculated, then obstacle presence in the setting area is detected..
-> Detection area is configurable by PC(RS-232C). For each area, it is possible to configure 3 outputs.
-> It is possible to switch the 15 detection areas configured by PC using external inputs.

Area setting Output 1 It is configurable from 0 to 10m in optical axis direction with 7 points.
Output 2,3 Linear or fan-shaped setting in optical axis direction,
Percentage setting is a ratio of output 1
2 scans mode It is configurable for each output of each area.
Hysteresis 10% of detection distance or less (it does not get less than 60mm)
Output Photo-coupler/NPN open-collector output(30VDC 50mA or less)
Output 1,2,3 : output OFF when obstacle is area, malfunction output : output ON when operating normally*
Inputs (1 to 4) Photo-coupler input (Common anode, each input current is 4mA or more), They control the current detection area.
Detection area setting It is switched by inputs (1 to 4)
Emission is stopped when all inputs(1 to 4) are ON
(OFF : H level input, ON : L level input)
