Hi all
I have a number of brand new coax relays, brand Bernier type LMT/B/1023526/2
with N-type connectors. They are NO configured and makes when power, which
somewhere between 60 to 110V DC, is applied. The coil has a DC resistance of
4.5 kohm with the dimensions 50 x 25 mm outer measurements of bobbin (Sorry,
I'm metric). Can anybody give a rough figure of what size wire and number of
turns to make it a 12VDC relay? I don't have any relevant books for this
kind of calculations and I am probably  too rusty in the math anyway..
