Power ON
The Sensor is ready to sense an object within 200 ms after turning the
power ON. If the load and Sensor are connected to different power
supplies, always turn ON the Sensor power first.
Cable
Use an external power cable of cross-section of 0.3 mm² or more for
the Amplifier, and the total length of the cable must be 30 m or less.
Connecting Sensor Heads
Connecting and Disconnecting Sensor Heads

<Removing Amplifier Units>
Slide one Unit away from the other and remove them one by one. (Do
not remove the connected Units together from the DIN rail.)
Note: 1. When the Amplifier Units are connected to each other, the
operable ambient temperature changes depending on the
number of connected Amplifier Units. Check
Specifications.
2. Before connecting or disconnecting the Units, always
switch power OFF.
