. Mutual interference |
To prevent mutual interference, be sure to space the two switches at a distance |
greater that shown in the table below. |
d=diameter a=gap a>=3d |
|
.In connecting the proximity switch with contact-type switch in series or in para- |
llel. The trouble will be the response time will get slow down and the proximity sw- |
itch may run out of order due to insufficient voltage. That's why we do not reco- |
mmend the way. |
.Loads with high current such as lamps, motors, etc, cause damage to the swi- |
tchingelement of a proximity switch. When making or breaking such a load which |
exceeds the capacity of the switches, be sure to use the proximity switch through |
a relay. |
.Surge protection |
It is recommended to insert a surge suppresser, as a varistor, into two sides of |
proximity switch to protect any large surge source. |
.Use of metallic conduit |
If a high voltage or power line runs near the proximity switch cable, be sure to |
wire the switch cable through a metallic conduit to prevent the switch from malfu- |
nction or damage. |
. Effect of cable length |
The operating characteristics of the proximity switches do not vary when a longer |
cable is used. However, taking intoaccount the voltage drop. |
.Connect power line action |
When power on the proximity switch, it will require 100ms to get stable. So., |
when power on , please to operate after 100ms, to move target toward or away |
the proximity switch after the time. |
|
,DC type connecting method of AND & OR |
|
|
,Correct operation directions for AC type |
.Connection to power source |
Be sure to connect the proximity switch to the power source through a load. Di- |
rect connection of the switch may cause damage to theinternal elements of the |
switch. |
|
.There will have a false motion. Whenever the load current is under 3mA. |
This is a normal phenomenon. This phenomenon can be avoid,
if another resistor |
is connected in parallel,to increase the load current over 3mA. The parallel |
resistance (R) and consumption power (w) can be calculated as following: |
