Wiring length to WB Sensor

[bcroe at juno.com]

The wires to the heater need to be heavy enough 
to avoid much voltage drop.  If the voltage at the 
sensor heater wires (Orange-Yellow) is 0.1 volt 
lower than the voltage at J1-J2, its time to look 
for heaver wires.  

The other 5 wires have currents below 1/100 amp,
so wire gauge is not important.  However wires in 
a very noisy (electriclly speaking) area could pick 
up some noise.  I have been using shielded wire 
for lengths over 10 feet, a bit conservative.  A really 
long cable might cause instability in the servo loop, 
but probably only with very high capacity cable and 
hundreds of feet .
