中国香港采购需求：12v光电传感器，24v光电传感器，8cm感应距离光电传感器，背景抑制光电传感器，背景抑制传感器npn，直流光电传感器

We are currently seeking diffuse photoelectric sensors suitable for object detection within a distance range of 1 to 2 meters. These sensors should ideally feature background suppression to enhance detection accuracy. We are looking for units with either normally closed (NC) or normally open (NO) outputs, or alternatively, those that support RS485 communication protocols. Our projected order quantity is approximately 300 pieces, and the delivery location will be in Hong Kong. If you have compatible products available, please provide detailed specifications, pricing, and lead times at your earliest convenience. Your prompt response will be greatly appreciated as we aim to finalize this procurement soon.
