Wiring Diagram:
Explanation of technical terms:
Main features: Take high frequency oscillation type proximity sensor(front detector)as representative example to briefly explain general features of proximity switch.
Correct use, installation and cautions:
■ Cautions ◆DC switch should adopt insulation transformer and ensure stable voltage mains corrugation. ◆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. ◆Set the switch use distance within the rated distance to avoid the effects from temperature and voltage ◆Wiring while power-on is strictly prohibited. Connecting the wires strictly according to the wiring diagram and output return elementary diagram. ◆If there are any special requirements to the switch like water proof, oil proof, acid proof, base proof, high temperature proof or with any other specifications, the users are required to give clear indication when placing an order. We can produce accord -ing to the requirements of the use.
