 4) proximity switch load can be lights, digital relay coil or programmable logic controller PLC input module. 5) require special attention PLC digital input module receives three-wire proximity switches of the type selection. PLC digital input module can generally be divided into two categories: common inputs for the power 0V, the current outflow (Japanese model) from an input module, this time, be sure to use an NPN proximity switch; another common inputs Dongguan to the positive terminal of the power supply proximity switch, current flows into the input module that trap input (European model), retail point of Dongguan proximity switches, be sure to use PNP proximity switches. Do not choose the wrong. 6) Two-wire proximity switches limit the working conditions by, turned the switch itself must drop off when there are certain residual current flows, which should be considered when selecting. Three-wire proximity switches, although many of a line, but not troubled by the residual current unfavorable factors like proximity switch factory in Dongguan, work more reliably. 7) Some vendors will proximity switch "normally open" and "normally closed" signal at the same time leads to Dongguan proximity switch model, or add other features, such a case, press the product manual specific wiring. Classification proximity switch inductive proximity switch and capacitive proximity switches inductive proximity switch works: Inductive proximity switches are a kind of proximity switch output of the position sensor, inductive proximity switches by LC oscillator and high frequency amplification processing circuit composition, the use of metal objects can produce electromagnetic fields close to the oscillation sensor head when the internal objects produce a vortex. The eddy current reaction to the proximity switch, proximity switch oscillation damping ability to make inductive proximity switch internal circuit parameter changes, thereby recognizing the presence of metallic objects close, and then control the proximity switch on or off. This proximity switch can detect objects must be metal objects.
