| . 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: |
