At present, in the foreign industrial developed countries the Safety Sensors industry is generally at a more advanced level, the world's large enterprises are mainly concentrated in the Europe and Japan. Meanwhile, foreign companies have more mature equipment, strong R & D capability, the technical level is in a leading position. But foreign companies? manufacturing cost is relatively high, compared with china?s companies, the manufacturing cost is disadvantage.
