• DC 3-wire type
• DC 2-wire type
• AC 2-wire type
• Differential frequency
When installing several proximity sensor closely, it may cause malfunction due to mutual interference. Therefore, please use differential frequency for the application *Differential frequency type is only for 17 square.
• Connection of the power supply
When using DC 2-wire and AC 2-wire type, a load must be connected before applying power; otherwise, components can be damaged.
• In case of the load current is small
AC 2-wire type
It may cause return failure of load by residual voltage. If the load current is under 5mA, please make sure the residual voltage is less than the return voltage of the load by connecting a bleeder resistor in parallel with the load as shown in the diagram.
[ I:Action current of load, R:Bleeder resistance, P:Permissible power]
DC 2-wire type
Please make the current on proximity sensor smaller than the return current of load by connecting a bleeder resistor in parallel.
*W value of Bleeder resistor should be bigger for proper heat dissipation.
When several proximity sensors are mounted close to one another a malfunction of the may be caused due to mutual interference. Therefore, be sure to keep a minimum distance between the two sensors as below chart indicates.
