Instructions on how to use the sensors properly
Particular at tention must be paid not to exceed the working limits list.Do not exceed specification.
1. Reed switch type connection polarities must be respected.
2. Connect the brown wire series load to the positive (+) and the blue to the negative (-) of power source.
2-1. If these are inverted the sensor remains switched,the load connected and the LED turned off; however this would not damage the circuit.
 
1.

Solide state and reed three-wire type connection polarities must be respected.Ex.as illustrated below.

2. The black wire have to connect to the "Load".If the sensor perhaps be damaged.
1. The external protect element is required.If sensor is used with inductive load.Ex.relayˇBsolenoid valve.
2. The load inductive as illustrated below : DC use diodeˇF AC use R-C circuitˇC
 
  * Keep out the strong magenticˇBmetal and high frequency field to get rid of interference. *
