This product features: - IP67 - relay outputs - shock, vibration - cylindrical transmit / receive unit makes installation easier - an independent external controller has adjustable gain knobs - very good resistance to light, can reach 100,000Lux and is not dirt, dust and other effects - the transmitting unit and a receiving unit into two separate parts so that when you install more flexibility to adjust the angle of the famous Telco is a major commitment to the development and production of photoelectric sensors Danish companies. Telco's products can be widely used in the escalator. Telco product performance is very excellent, able to adapt to the environment in different places on Earth. Here, we have to explain this type of economy as photoelectric sensors. Describes the installation instructions and debugging methods of this product in detail.
