As I told earlier, this component is not a difficult to get one. I assume that, it is an infra-red type. It is very cheap and easily available. Unfortunately, I didn't uploaded a picture of it here, and I can't do it hereafter by this window. If it is an ultra-sound receiving one, your part might be right. Such sensors are no rare in the electronic spare part market. anyway, if you give me your email here by this window, I'll post the picture and other details by return mail.
