Triple Level Sensor/Actuator
Product Description
The XB3UK sensor terminal
blocks reduce installation
time by terminating three-
wire devices such as
photoelectric and proximity
sensors in a single terminal
block. The XB3UK Series
accommodates a design
where the positive and
negative connections are
grouped so that only the
signal lines and one pair of
wires for the power supply
need to be wired between
the terminal box and the
control. The upper level
accommodates the markable
feed-through terminals for
the signal line. The two lower
terminal points can be
bridged. These are used for
the sensor power supply.
The positive and negative
potential can be fed into the
bridges with XB3UKF25. The
first sensor can also be
connected to this three-wire
feed-through block.
