Is it possible to connect two Proximity Sensors in series ?
- The following points should be taken into account:
- Series wiring is only possible using sensors with wide voltage limits.
U sensor =U (supply) / n sensors
U sensor and U supply must remain within the sensor’s voltage limits.
- If only one sensor in the circuit is in the open state, it will be supplied at a voltage almost equal to the supply voltage.
- When in the closed state, a small voltage drop is present across each sensor. The resultant loss of voltage at the load will be the sum of the individual voltage drops and therefore, the load voltage should be selected accordingly.
