NSR66-BM Belt Misalignment Switch

NSR66-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 3 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 heavy-duty design. Anti-static powder coated aluminium cast enclosure is resistant to corrosion and oxidation. Shaft mechanisms are made of stainless steel and all internal parts are metal cast. NSR66-BM series products do not require any maintenance.

Standard product's contact structure is 2NO+2NC. The switch arm will actuate the alarm switch at 15° angle. Corrective action can be taken before further misalignment. If the belt drifts further and the switch arm rotates until 25°, the second microswitch will be actuated and the system will stop. Can be customized with both switches working at the same angle.


All models designed according to relevant UL and CE standards.
