NSR66-PR Pull Cord Switches

NSR66-PR Pull Rope Switches are designed for shutting down a conveyor belt or machinery and assuring system safety. They are also referred as "Pull Rope Switches". They are mounted alongside the conveyor belt, with tensioned steel cords attached to the switch arm from either side or both sides. When the cord is pulled, switch arm will turn until the locking angle and system shuts down. The switch can be reset manually with resetting lever.

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 mechanism is made of stainless steel and all internal parts are metal cast. NSR66-PR series products do not require any maintenance.

In standard applications, cord length is 50 m to both sides. All models can be equipped with an alarm switch and signal light so alarming switch can be spotted from distance. Standard product's contact structure is 2NO+2NC. The switch body can be mounted vertically or horizontally.


All models designed according to relevant UL and CE standards.

We recommend tested and approved KBT Connection Equipment for installation.
