NSR12-PS Conveyor Belt Position Switch

NSR12-PS Position Limit Switches are designed to alarm and/or shut down a conveyor system in the event of belt drift and misalignment. They are mounted under the conveyor belt. In the event of belt drift, the roller will rotate and actuate microswitches at specified angles.

The product is suitable for reliable long term usage in most industrial applications. Enclosure is aluminum cast and other parts are made of CuZn39Pb3 (brass). NSR12-PS series products do not require any maintenance. It offers an economical solution to short distance conveyor belt and machinery safety applications.

With the single contact model, the system will stop when the switch arm rotates until 25°. With two contact model, the switch arm will actuate the alarm switch at 15° angle. Corrective action can be taken before further misalignment. If the belt drifts until the switch arm rotates until 25°, the second microswitch will be actuated and the system will stop. Contact structure can be customized.

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