The potentials of the XBUTT double-level terminal blocks are on two
levels to reduce space requirements by 50% over single-level
terminal blocks. The XBUTT Series can be bridged on both levels for
maximum flexibility. Marking can be provided at each termination point.
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 feedthrough block.
