Working principle:
• By comparing the light intensity on two sensing PN detectors to determine whether the object is far or near.
• Distance is set by mechanically adjust the base line distance between the emitter lens and the receiver lens
Features:
• Two-pixel photo ASIC specially designed for BGS sensor
• Sensing distance: 35~500mm
• Less sensitive to target color
• Ignores reflective backgrounds
• Sensitivity adjustable
• Small black/white Difference: ≤10%
