XXX Series

CS Series Anti-vandal Switch

Example Use Case

Example Use Case for the CS4M22R Capacitive Switch

Example Use Case:

• Desired Outcome:

o On State: Green LED Illuminated

o Off State: Red LED Illuminated

• Schematic:

• Wire power (5-24VDC @ 1A) to pin 6 and ground to pin 1

• Connect NPN pin 5 of CS4M22R to an input pin of a pull-down integrated circuit (IC). This will allow the desired

LED to be illuminated during the ON or OFF states

o If pin 5 is outputting voltage, then we will have the green LED illuminated to show a running state

o If pin 5 is not outputting voltage, then we will have the red LED illuminated to show a stopped state

• Connect red LED pin 4 of CS4M22R to an output pin of a desired IC that is also connected to NPN pin 5

• Connect green LED pin 3 of CS4M22R to an output pin of a desired IC that is also connected to NPN pin 5

• Send a high signal from the IC to the red LED when the green LED is active and pulling low. This will prevent the

red from illuminating

• Send a high signal from the IC to the green LED when the red LED is active and pulling low. This will prevent the

green LED from illuminating

• If power pin 6 and ground pin 1 have been wired to the switch each LED can be grounded for constant

illumination if desired. This illumination will ignore the state change of the switch

• Remember to use any needed resistors to avoid damaging components
