Smart door contact

Paid on delivery
We are willing to create a smart hatch contact to detect the opening of the hatch of a milling machine. Regular magnetic door contacts are not suitable because the operator could fail it using a piece of magnet. The device we would like to produce should work only with the pre assigned activator piece. We think it could be done by using PCF7936AS transponder chip and its receiver PCF7936. There has to be an RS-485 interface to communicate with the device. That interface should provide the hatch/contact position (open or close) information and also be used to program the contact to assign an activator. You could find some information about the transponder chip at [login to view URL] : [login to view URL]
