A substantial increase in independent photoelectric sensor photoelectric sensor mounted side by side installation and cabling work applicability sensor unit design theme can be carried out separately, in order to save time and into force. Ruoyin sensor theme damaged and must be replaced, or because of changes in specifications and must replace the different types of sensors, sensor theme simply replace it. High durability of metal-adjusted head high durability and long life metal head Unlike conventional resin head as easily be damaged or broken. Two sensors mounted side by side alternating frequency PZ2-41 (P), PZ2-42 (P), and PZ2-61 (P) can operate in alternate frequencies, so you can put two sensors installed in a very close distance. PRO features a newly developed improved stability detection PRO features: the horizontal component of the optical axis of the system transmitter PZ2-61 waves emitted through the rear polarizer level only, while the receiver will only accept vertically through the rear vertical polarizer components. PZ2 Series Photoelectric Sensors in automation and sensing applications impeccable performance. Float float material automotive and metal industry ring material floating its detection (PZ2-61). Wheels for wheel detection (PZ2-61) automobile and metal industry through the wheel. Wheel detect tire tire automotive and metal industry presence detection (PZ2-61). Detection box to confirm whether the detection box parts boxes of food packaging industry
