Hokuyo - UBG-05LN
Accuracy is greatly improved compare with PBS series.
With DC24V, this sensor can be broadly used for control system or equipment. Field pattern: 31.
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.
