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.
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 using DC or AC 2-wire type proximity sensor, the load must be connected, otherwise internal components may be
damaged. The load can be connected to either wire.

Mutual-interference & Influence by surrounding metals
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.
When sensors are mounted on metallic panel, it is required to protect the sensors from being affected by any metallic
object except target. Therefore, be sure to provide a minimum distance as below chart indicates.
