XR and XF - Limit switches

Screw limit swiches and Overtravel limit swiches - XR and XF

Benefits

The screw limit switches are designed to monitor the movement of an object via an input drive.
The overtravel limit switches for power circuit switching are specifically designed to ensure the safety of hoisting equipment.
They directly break the power supply to the hoist motor if the load being handled accidentally exceeds the operating limits of the equipment.

Applications

Position control of moving parts of hoisting or materials handling equipment (winches, travelling cranes, gantries, cranes, rotary excavators, etc.).
Liquid level control in pumping systems.
