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.

Technical Parameter

Model No. PBS-03JN
Power source 24VDC(Allowable range 18 to 30VDC including ripple)
Current consumption 250mA or less(100mA or less when emission stops)
Except for I/O terminal current and rush current(500mA)
Light source 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 the scanning center position) and within scanning angle 180°
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)
Output response time 180msec or less(Scanning speed 1 rev./100msec)
280msec or less when 2 scan mode (except for 100msec, area switching time)
Input response time Input capture period : 1 scan time (100msec)
LEDs Power LED(Green) : Flickered when trouble
Output 1, 2 and 3 LED(Orange) : Lights up when obstacle is in area
Connection 1m flying leads cable
Ambient illuminance(note) Halogen/mercury lamp : 10,000lx or less, Fluorescent lamp : 6,000lx or less
Ambient temperature/humidity -10 to +50 degrees C, 85%RH or less(No condensation, no icing)
Vibration resistance 10 to 55Hz, double amplitude 1.5mm, 2 hour in each X, Y and Z directions
Impact resistance 490m/s2, 10 time in each X, Y and Z directions
Protective structure IP64(IEC standard)
Lifespan 5 years(motor life)
Materials Front case : Polycarbonate, rear case : ABS
Weight Approx. 500g

* Output 1 to 3 are OFF when malfunction output is OFF. 
Note) Strong light such as sun light may introduce a sensor malfunction.
