- Angular scanning range 217.8°
- Range 200 to 3000mm
- Power consum. 24Vdc @250mA
- RS232 interface
- Size 75 x 70 x 60mm
- Weight 500g
Features
- 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.
