NSR22-BM Belt Misalignment Switches

NSR22-BM Belt Misalignment Switch is a conveyor belt safety accessory designed to alarm and/or shut down conveyor systems in the event of a conveyor belt misalignment.It is designed to prevent damage to the belts and equipment due to the misalignment of the conveyor belt system.

NSR22-BM series of products do not require any maintenance. 

Materials used:

The body structure is covered with aluminum cast static paint that is resistant to corrosion.Shaft and Arm mechanisms are made of stainless steel.

Uses and Applications:

It is mounted on both sides of the conveyor belt to be attached to the chassis.If the belt begins to deviate, it makes contact with the roller arm causing it to spin. As more force is applied to the roller arm, it will rotate away from the normal position.

At a 15°, it will actuate the first alarm microswitch. The first microswitch will annunciate the alarm condition to the control system. If the belt continues to slip, the system is stopped by activating the second microswitch at a 30 ° position.

Safety Features:

The heavy-duty rugged design makes them suitable for most industrial applications.It can be used with only one contact mechanism without using alarm contact.

General Description:

The roller arm of the switch is placed about 15 cm away from the normal belt position.
