Cable Lengths
Recommended maximum cable length for voltage-mode input
devices is 50 feet, due to possible signal degradation and electrical
noise immunity in typical industrial environments.
When using shielded cable wire, ground the foil shield and drain
wire only at one end of the cable. We recommend that you wrap the
foil shield and drain wire together, and connect them to a chassis
mounting bolt, grounding stud or chassis single-point grounding
point. Use heat shrink tubing to seal the exit point of the wires. At
the opposite end of the cable, tape exposed shield and drain wire
with electrical tape to insulate it from electrical contact.
