TPR22-BM-EX Belt Misalignment Switches

TPR22-BM-EX BeltMisalignment Switch is a conveyor belt safety accessory designed to alarm and/or shut down conveyor systems in the event of a conveyor belt misalignment.

TPR22-BM-EX series of conveyor belt pull cord switch do not require maintenance.

Materials used:

The Body structure is made of BMC composite material. It is resistant to corrosion and explosive gas. Shaft mechanisms are made of stainless steel. The handle mechanism is cylindrical in structure and operates with two bearings.

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 35 ° 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.

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

Available modifications as per request:

-           The alarm contact structure can be added
