Anti-side switch is used to detect deviation can be fixed belt conveyor stringers at the top or bottom, usually installed at both ends of the belt away from the head or tail pulley from 0.3 to 2 m of the place. 
 Belt deviation, the deviation from the force arm movements, alarm touch micro switch. If you continue to deviate to stop contact, touch another set of contacts, it will protect the conveyor downtime. 
 ? Universal design allows installation of free anti-bias switch mounted on the top or bottom of the conveyor stringers 
 ? Rugged cast aluminum housing, protection standards NEMA4, special circumstances optional special surface treatment 
 ? Integral cover Easy wiring and adjustment

 Deviation switches were installed in the belt conveyor head and tail both sides of the rack unit. Switch roller axis deviation in the normal state (no deviation), the axis orthogonal roll and tape the edge line (vertical), the distance between about 80-120mm. When the tape should be partial load and shift, when the swing axis roll angle ≥ 30 °, the internal micro switch operation, early warning signal or control circuits cut off the belt conveyor downtime. When troubleshooting, the deviation switch has returned to normal.
