I'm dealing with a automotive machine which use D4SL-N2HFG-DN for detect whether the door of machine is fully close.

I have few question regarding this device:

1) Regarding the door open / closed detection at terminal: 11--12, 21--22, 31--32
Is it we can connect any 3 of the terminal to PLC so that we can detect whether the door is closed? (Please refer to Operation.JPG)

2) What is the usage of E1(+)----E2(-) terminal. Is it affected by terminal: 41--42, 61--62? (Please refer to internal circuit.JPG)
