  • Responce time 180msec or less

  • Angular scanning range 217.8°

  • Range 200 to 3000mm

  • Power consum. 24Vdc @250mA

  • RS232 interface

  • Size 75 x 70 x 60mm

  • Weight 500g

The PBS-03JN is a popular alternative to laser range-finders in indoor environments. The sensor is popular due to its low cost, low power consumption and light weight design.

Applications include:

  • Automated Guided Vehicles
  • Robotics
  • Security
  • Automation


  • This was 60% smaller than PB9 about cubic volume. Scanning angle(Detection area) is increased to 180° and detectable dead zone is getting smaller.
  • Operation principle is that semicircular field is scanned by LED(lambda = 880nm) and the coordinates is calculated by measuring distance to object and its step angle and then it detects obstacle in 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.
Model Number 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 scanning center position) but within scanning angle 180°

Area Setting Output 1 It is free to set from 0 to 10m for optical axis direction with 7 points pointer.
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.
Hysteresis 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)

Output response time 180msec or less (Scanning speed 1 rev./100msec) 280msec or less when 2 scanning mode (but except for 100msec, area changeover time)
Input response time Input taking-in cycle : 1 scanning time (100msec)
Input Responce Time Input taking-in cycle : 1 scanning time (100msec) (1msec when choosing emission-stop by outer input

Power lamp (Green) : Flickered when trouble

Output 1, 2 and 3 lamp (Orange) : Lights up when detected in area

Connection method Lead wire 1m long
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 (Not condensing, not icing)
Vibration resistance 10 to 55Hz, double amplitude 1.5mm Each 2 hour in X, Y and Z directions
Impact resistance 490m/s2, Each 10 time in X, Y and Z directions
Impact resistance 196m/s2 Each 10 time in X, Y and Z directions
Protective structure IP64 (IEC standard)
