- Aluminium Casting Body - ATEX Certified for Dangerous Environment - 2NO / 2NC Contact Structure - CE, EAC Standards - 3 Years Replacement Warranty NSR55-BM-EX Belt Misalignment Switches are designed to alarm and/or shut down a conveyor system in the event of belt drift and misalignment in hazardous environments where explosions could occur. 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. Anti-static powder coated aluminium cast enclosure is resistant to corrosion. Shaft and arm mechanisms are made of stainless steel and all internal parts are metal cast. NSR55-BM-EX 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. NSR55-BM-EX is Ex-Proof (ATEX certified). With its protection against dust ingress, it is reliable in explosive athmosphere. All models conform to CE (European Union) and EAC (Eurasian Customs Union) standards. Microswitches used in these products are VDE approved
