- 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.
