Power Load Requirements and Maximum Mounting Distances

Consider future needs when selecting cable size and power supply. The maximum distance between the X5000 transmitter and the power supply depends on the sensor configuration (sensing technology and one or two sensors), wire gauge, and the power supply voltage. The tables below outline the maximum transmitter mounting distances. First determine if the sensor(s) will be locally or remotely mounted. Then choose sensor type(s). The corresponding nominal maximum power and mounting distances by wire gauge are shown.
