Conveyor Belt Deviation Switches
Conveyor Belt Deviation Switches​The conveyor belt deviation switch has two levels of angle, generally used: the first angle is: 10, 12, 20. The second angle is: 30, 35, 45.

The conveyor belt deviation switch has two levels of angle, generally used: the first angle is: 10, 12, 20. The second angle is: 30, 35, 45.


Introduction

The deviation switch is a product used to detect the deviation of the conveyor belt of the belt conveyor. It is a safety protection device for the automatic warning and shutdown of the conveyor belt in the event of deviation.

Working principle

As belt misalignment, belt edge drives vertical roll of belt sway switch rotation and make it inclined, if incline more than first action angle, output one set signal, if incline more than second action angle, then output another set single, the two sets of signals represent alarm or stop. After normal running of conveyor, vertical roll of belt sway switch restore automatically.


Structure features

1. Aluminum alloy shell reaches high strength, lightweight, shell of belt sway switch can reach IP 67, it can be worked at extremes environment for long time.

2. Large capacity of electric shock, moves sensitive and reliable.


Usage and installations

Fix belt sway switches on frame, then weld on the conveyor machines, Axis of vertical roll with belt consist by 90°, distance between vertical roll and belt edge is 50 to 100 mm. Belt edge is at the position of 1/3 vertical roll of belt sway switch, and every 50 meters need install one couple of belt sway switches.


Connection cables

Belt sway switches are equipped four-core cable, and mark No.1, No.2 No.3 and No.4 cables. No.1 and No.2 are normal open contact, No.3 and No.4 are normal close contact, if two normal open and two normal close, please advise it before ordering.
