Specifications - Installation and Operating Instructions
Series CBAS Belt Alignment Switch
The Series CBAS is a rugged and reliable conveyor belt align-
ment switch. The compact die cast aluminum housing is de-
signed for easy installation. The switch cover allows for simple
access to wiring terminals and CAM adjustments. Belt alignment
switches are typically used in pairs with one switch on each side
of the conveyor belt mounted near the first and/or last pulley of a
conveyor. Each series CBAS is equipped with two micro switch-
es, allowing one actuation angle for small belt deviations and a
second actuation angle for extreme belt deviations. The actua-
tion angles are factory set at 20 degrees and 35 degrees, each
actuation angle can be easily adjusted in the field to fit any ap-
plication.
