Extended Temperature Version (ET)

Notes:
• Connect shield to ground at one end only!
• If Sensor mounting is grounded, leave cable shield disconnected
• If Sensor mounting is not grounded, connect cable shield to ground
The longer the cable, the more susceptible it is to noise and earth loops. We
recommended using cable with heavy gauge conductors and good RF/electrical shielding
(copper braid rather than drain and foil). A proper junction box close to the sensor is an
ideal location not only to extend the cable, but to also to configure the wiring for high or
low sensitivity range operation.
