UBG-05LN

FDA approved
SOKUIKI sensor

UBG-05LN

Compact laser obstacle detection sensor with wide detection range (5m x 4m)
Wide detecting area(5m×4m)

Feature

  • Operating principle is that semicircular field is scanned by laser(λ=785nm) and the coordinates is calculated by measuring distance to object and its step angle and it detects obstacles in setting area.
  • Scanning angle(detecting area) is 180° and detecting area can be free to set with 0.1 to 5m(length) and 4m(width) and it can set detecting distance with 3 steps output per each area.
  • It can change the detecting area(31 kinds max.) that was set beforehand by outer bit input.
  • Power source is 24VDC and current consumption is 150mA or less.
