The CSDA1DA is a 3-pinout style Digital Current Detector with open collector output and sinking output. It is made up of PET polyester housing. The MICRO SWITCH CS series digital current sensor provides a logic level output that changes from approximately Vcc to 0.4V when the sensed current exceeds the operate point. Each digital sensor will operate on AC/DC current but the output will turn off at every zero crossing when sensing AC current.
