TPR55-BM Limit Switch – Conveyor Belt Alingment Switch

TPR55-BM Belt Misalignment Switches are designed to alarm and/or shut down a conveyor system in the event of belt drift and misalignment. They are mounted on both sides of the conveyor belt, with roller arm of the switch positioned 15 cm away from the belt. As the belt starts drifting into either side, it will first contact with the switch arm. Arm will roll without distrupting the belt. If belt continues to drift further the switch arm will rotate and actuate microswitches at specified angles.

The product is suitable for reliable long term usage in most industrial applications due to its durable design. Its BMC (durable composite) enclosure is corrosion and oxidation proof. Shaft and arm mechanisms are made of stainless steel and all internal parts are metal cast. TPR55-BM series products do not require any maintenance.

The switch arm actuates the alarm switch at 15° angle. If the belt continues to drift and the switch arm rotates until 18°, the second microswitch will be actuated and the system will stop. Can be customized with both switches working at the same angle.

All models conform to CE (European Union) and EAC (Eurasian Customs Union) standards. Microswitches used in these products are VDE approved.

What are the Usage Areas of Limit Switch?

Products known as the specific limit switch, lever belt slide switch or limit switch prevent the conveyor belt belt from misalignment. For this reason, damages that may occur in the system are prevented. Our limit switch products are used in heavy industry and may industrial areas. The limit switch is known as a necessary equipment in all enterprises where the conveyor belt system is used.
