Description

The RK 1/K/RN/Ex-1G JOLA limit switch is particularly suitable when the use of conventional limit switches is questionable due to harsh working conditions, e.g. in damp or dirty environments.

RK Ex limit switches shall be mounted through a through-hole located in the centre of the switch body.

Through this hole, the limit switch must be mounted on the horizontal metal shaft of the stacker device, allowing a rotation of max. +/- 180 °. The rotational movement of this shaft activates the switching process.

To prevent the limit switch from malfunctioning and the cable from breaking, you must leave enough cable length. Once the limit switch is set on the shaft, it must be fixed with a screw placed inside the switch body.

RK Ex limit switches are equipped with a micro-switch (change-over contact) as the electrical switching element, and this element is activated by an internal metal ball.

Limit switches are not suitable for use on rotating shafts
