What is Photoelectric switch?
A proximity sensor is a sensorable to detect the presence of nearby objects without any physical contact.
A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the fieldor return signal. The object being sensed is often referred to as the proximity sensor's target.

How to use our photoelectric switch?
What's the caution terms of our promixity switch?
(1) Should we use insulation transformer when using the DC switch?
Answer: Dc switch should adopt insulation transformer and ensure stable voltage mains corrugation.
(2) How to do when electric power line passes through the surrounding of switch lead-wire?
Answer: If any electric power line or dynamic line passes through the surrounding of switch lead-wire, in order to prevent the switch from damage or error action ,cover the metal bushing on the switch lead-wire and ground it to the earth.
(3) Why should we set the switch use distance?
Answer: Set the switch use distance within the rated distance to avoid the effects from temperature and voltage.
(4) What should we pay attention to when wiring?
Answer: Wiring while power-on is strictly prohibited. connecting the wires strictly according to the wiring diagram and output return elementary diagram.
