Series & parallel connection

When the proximity switch is connected in parallel (NPN,PNP type can not be mixed use),Proximity switch any action can drive load.The quantity of the proxim switch depends on the sum of leakage current.As long as the action does not affect the load, proximity switch can be more connections.

When the proximity switch is connected in series (NPN, PNP can be mixed use ), Only when all of the action at the same time, the proximity switch ca drived the load.The quantity of proximity switches depens on the sum of saturation voltage.As long as the action does not affect the power and voltage, proximi switch can be more Connections.  Proximity switch response frequency is the initial reset accumulation of each proximity switch.

matters need attentions

Cautions when connected or disconnected with the power supply

When connecting the proximity switch with the counter and the programmable controller ,there isn't any problem because of built-in initialized reset circui please avoid the conditions mentioned below

The detection object lies around the detection distance of the proximity switch;For DC voltage type and DC switch switch type,when power supply is turned on (turned off),time constant rises(drops)greatly;there is self-excitation and noise when the AC switch type proximity switch is power-on(off)

Capacitor,light load

The proximity switch can't have the capacitor or light that has larger jumping current as the load directly connected to be connected through a relay or series connected with a current-limiting resistance.The peak cuttent set by current-limiting resistance ris within the load current of proximity switch;Make sure to connect through load.
