Enhanced Life
Product Description
Renew’s RL7 series horizontal limit switches are designed for greater durability and resistance to harsh environments, up to 10 million operations of mechanical life, making them suitable for critical and heavy-duty roles where normal basic switches could not be used. The panel mount plunger switch features easy integration into control panels and equipment housings. Add a roller and it becomes panel mount roller plunger switch, which combines the robustness of a panel mount design with the smooth operation of a roller plunger. Two directions of the roller are available to meet different switch applications.

Application
Renew's horizontal limit switches play a vital role in ensuring the safety, accuracy and reliability of equipment in various fields. Not only do these switches effectively prevent equipment from exceeding its intended operating range, they also provide necessary feedback during various operations, thereby improving overall system performance and stability. The following are some areas of widespread application or potential application:
Elevators and lifting equipment
This limit switch is installed on the edge of the elevator door and is mainly used to detect whether the elevator door is completely closed or opened. This feature is crucial because it not only ensures the safety of passengers when entering and exiting the elevator, but also prevents the elevator from starting without the door being fully closed, thus avoiding potential accidents.
