Parallel connection of a 2-wire output sensor and/or mechanical switching devices is not advisable.

In fact, if one of the two sensors connected in parallel is in the "OFF" state, the second sensor will no longer be supplied with power. When the contact changes to the "ON" state, the sensor will not be available immediately because it is being powered up.

Operation may be acceptable if the sensors are activated alternately one after the other. Otherwise, they may be damaged.

This type of connection should therefore be avoided.
